SUMMARY:Tedori-Callinan Lecture: "Resist Fatigue by De-concentrating Stress"
DESCRIPTION:Most materials suffer from a disease: fatigue. Symptoms include degradation of properties and growth of cracks under cyclic stretch. These materials are unfit for applications involving prolonged and cyclic loads. A crack grows in a material because the crack tip concentrates stress. Recently\, we have been developing fatigue-resistant materials by de-concentrating stress\, through mechanisms at either microstructural or molecular scale. This talk describes the mechanics and implementations in materials.

SUMMARY:CIS Seminar:"David V.S. Goliath: the Art of Leaderboarding in the Era of Extreme-Scale Neural Models"
DESCRIPTION:Scale appears to be the winning recipe in today’s leaderboards. And yet\, extreme-scale neural models are still brittle to make errors that are often nonsensical and even counterintuitive. In this talk\, I will argue for the importance of knowledge\, especially commonsense knowledge\, and demonstrate how smaller models developed in academia can still have an edge over larger industry-scale models\, if powered with knowledge. \nFirst\, I will introduce “symbolic knowledge distillation”\, a new framework to distill larger neural language models into smaller commonsense models\, which leads to a machine-authored KB that wins\, for the first time\, over a human-authored KB in all criteria: scale\, accuracy\, and diversity. Next\, I will introduce a new conceptual framework for language-based commonsense moral reasoning\, and discuss how we can teach neural language models about complex social norms and human values\, so that the machine can reason that “helping a friend” is generally a good thing to do\, but “helping a friend spread fake news” is not. Finally\, I will discuss an approach to multimodal script knowledge\, which leads to new SOTA performances on a dozen leaderboards that require grounded\, temporal\, and causal commonsense reasoning.

SUMMARY:CBE Seminar: "The Refinery of Today\, Tomorrow and the Future: A Separations Perspective"
DESCRIPTION:Abstract \nThe hydrocarbon processing industry is in the midst of a major shift in feedstocks\, structure\, and products. Aggressive carbon abatement targets and intrinsic efficiency advantages from electric vehicles strongly undercut the advantages of fossil fuels\, which are the majority product of this industry. However\, the immense value of the existing hydrocarbon infrastructure suggests that fossil feedstocks\, processing\, and products will be the dominant form for quite some time. Existing fossil-based plants with compatible equipment (e.g.\, hydrocrackers) will begin the externality-induced transition over to bio- and e-refinery formats to leverage this valuable existing infrastructure and logistical connections. Advanced separations play a role in this transition in several ways. First\, advanced separations can partner with existing separation units (e.g.\, distillation) to extend the time in which fossil-based processing remains competitive under modern externalities (e.g.\, CO2). \nMoreover\, energy- and capital-efficient separation technologies can mitigate the decrease in returns of energy invested in fossil-based refining\, due to greenhouse gas emission mandates. While bio- and e-refineries are often thought of as a greenfield for advanced separations technologies (thus bypassing the problem of working\, amortized capital in existing plants)\, in fact\, the adaptation of existing fossil-based refineries to renewable feedstocks suggests that the “hybrid” separation system paradigm is likely to be the standard for years to come. Nevertheless\, these “green refineries” introduce many new separations challenges that are likely to be poorly addressed by conventional technologies. Finally\, decades-old regulatory definitions of fuels will continue to promote distillation-centric refinery designs – flexibility in not only these regulations\, but also in end use will pave the way for low energy\, low carbon separation techniques. In this talk\, comments on the future of the refining industry and the role of separations systems in the future will be discussed\, in addition to specific research challenges facing membrane and adsorption technologies.

SUMMARY:MEAM Seminar: "Computational Mechanics for Landing on Mars"
DESCRIPTION:Current technology for decelerating a spacecraft from the high speed of atmospheric entry to the final stages of landing on Mars is based on low-density supersonic decelerators such as low mass and high packaging efficiency parachute systems. To enable future exploration missions featuring sophisticated robots and safely land heavier spacecraft on Mars\, larger than before high-speed parachutes and inflatable drag devices are needed. The design\, development\, and maturing of such devices for future use at Mars require guidance from predictive simulations based on a high-fidelity\, multi-disciplinary computational model for parachute inflation dynamics (PID) and drag prediction. The development of such a model is a formidable challenge. It must account for shocks\, turbulence\, and porous flow boundary conditions; the complexity of the behaviour of fabric material; massive contact between very thin surfaces; and highly nonlinear fluid-structure interactions in the presence of topological changes. The computational model must also be able to predict various instabilities of a parachute such as flutter and pulsation\, the influence on its performance of several design factors including material and geometric porosities\, and material failure. This lecture will discuss an ongoing effort at Stanford University\, in collaboration with NASA Ames and the Jet Propulsion Laboratory\, for the development of such a computational model and some associated computational innovations. These include: a multi-scale approach for modeling the dynamics of woven fabrics based on the concept of a locally attached microstructure and mechanics-informed machine learning; a discrete-event-free\, spurious-oscillation-free\, and total variation diminishing embedded boundary method for multi-material problems; a subgrid scale modeling approach for the treatment of porous wall boundary conditions; and an energy-conserving approach for the discretization of transmission conditions at the interface between fluid and structural representations of disparate spatial dimensions. The lecture will also report on validation results for the simulation of the supersonic inflation dynamics of: the parachute that landed Curiosity on Mars\, on August 6\, 2012; and those used in NASA’s 2018 ASPIRE tests to help decide which parachute design to use on the recent Mars 2020 mission that landed Perseverance on Mars\, on February 18\, 2021.

SUMMARY:ESE Fall Colloquium Seminar - "Distributed Estimation Under Privacy and Communication Constraints"
DESCRIPTION:Distributed estimation is a central task in modern data science\, where datasets are often generated from distributed sources or are too large to be stored on a centralized machine\, and communication is subject to bandwidth and privacy limitations. In this talk\, we will consider the problem of estimating high-dimensional distributions and their parameters from distributed samples under communication and differential privacy constraints. We will develop novel encoding and estimation mechanisms that simultaneously achieve optimal privacy and communication efficiency in various canonical settings\, including both probabilistic and so called “distribution-free” models. We will investigate both global (worst-case) as well as local complexity of these tasks\, where the latter captures the hardness of estimating a specific instance of the problem. We will complement our achievability results with information-theoretic lower bounds that describe how Fisher information from statistical samples scales with privacy and communication constraints. We will conclude by discussing how our theoretical results can be used to improve the experimental performance of federated learning algorithms.

SUMMARY:Fall 2021 GRASP SFI: “Diversity and Inequality in Social Networks”
DESCRIPTION:Abstract: Online social networks often mirror inequality in real-world networks\, from historical prejudice\, economic or social factors. Such disparities are often picked up and amplified by algorithms that leverage social data for the purpose of providing recommendations\, diffusing information\, or forming groups. In this talk\, I discuss an overview of my research involving explanations for algorithmic bias in social networks\, briefly describing my work in information diffusion\, grouping\, and general definitions of inequality. Using network models that reproduce inequality seen in online networks\, we’ll characterize the relationship between pre-existing bias and algorithms in creating inequality\, discussing different algorithmic solutions for mitigating bias. \n*This is a HYBRID Event with in-person attendance to watch the Zoom stream in Levine 307 and Virtual attendance via Zoom here…

SUMMARY:CBE Seminar: "Spatial and Dynamical Control in Metabolic Engineering Using Organelle Engineering and Optogenetics"
DESCRIPTION:Abstract \nMetabolic engineering aims to rewire cellular metabolism\, typically of microorganisms\, to produce fuels\, chemicals\, pharmaceuticals\, and other valuable products from renewable resources. However\, it is often challenging to achieve the titers\, yields\, and productivities required for commercial viability. Spatial and dynamical control of engineered metabolic pathways can greatly improve their efficiency to address this obstacle. We have developed strategies to enhance the flux and specificity of metabolic pathways by spatially compartmentalizing them in yeast mitochondria and synthetic organelles. This helps increase the local concentrations of enzymes and intermediate metabolites\, prevent metabolic bottlenecks\, and reduce metabolite loss to competing pathways. In addition\, I will present a new strategy to dynamically control metabolic pathways using optogenetics. There are many advantages of using light to control metabolic pathways\, including its orthogonality\, tunability\, and the ease with which it can be applied or removed instantly in any schedule to continuously manipulate metabolism throughout fermentations. I will present several optogenetic circuits we have built to control microbial growth and production with light\, the impact they have on chemical production\, and the strategies we have developed to overcome the limited light penetration of fermentations operating at high cell density in lab scale bioreactors. Finally\, I will provide a perspective on how these technologies may come together to prescribe a new paradigm for spatial and dynamical control in metabolic engineering to improve microbial chemical production.

SUMMARY:MSE Seminar: "Topological Physics: from Photons to Electrons"
DESCRIPTION:There are many intriguing physical phenomena that are associated with topological features — global properties that are not discernible locally. The best-known examples are quantum Hall effects in electronic systems\, where insensitivity to local properties manifests itself as conductance through edge states which are insensitive to defects and disorder. In this talk\, Dr. Hafezi will first discuss how similar physics can be explored with photons; specifically\, how various topological models can be simulated in various photonics systems\, from ring resonators to photonic crystals. He then will discuss that the integration of strong optical nonlinearity can lead to unique bosonic phenomena\, such as topological frequency combs\, topological source of quantum light and chiral quantum optics. These results may enable the development of classical and quantum optical devices with built-in protection for next-generation optoelectronic and quantum technologies. In the end\, Dr. Hafezi will cover the topological interplay between photonic and electronic systems. Specifically\, he investigates how light can create and manipulate topological states of electrons.

SUMMARY:BE Seminar: "Phage and Robotics-Assisted Biomolecular Evolution" (Emma Chory)
DESCRIPTION:This seminar will be held live and broadcast on zoom – check email for link or contact ksas@seas.upenn.edu. \nEvolution occurs when selective pressures from the environment shape inherited variation over time. Within the laboratory\, evolution is commonly used to engineer proteins and RNA\, but experimental constraints have limited our ability to reproducibly and reliably explore key factors such as population diversity\, the timing of environmental changes\, and chance. We developed a high-throughput system for the analytical exploration of molecular evolution using phage-based mutagenesis to evolve many distinct classes of biomolecules simultaneously. In this talk\, I will describe the development of our open-source python:robot integration platform which enables us to adjust the stringency of selection in response to real-time evolving activity measurements and to dissect the historical\, environmental\, and random factors governing biomolecular evolution. Finally\, I will talk about our many on-going projects which utilize this system to evolve previously intractable biomolecules using novel small-molecule substrates to target the undruggable proteome.

SUMMARY:GRASP on Robotics: "The Importance of Pneumatic Actuation in Adaptive Robotic Devices"
DESCRIPTION:Abstract: Soft pneumatic actuators have become a popular implement in modern robotic systems due to their intrinsic mechanical compliance\, which affords researchers levels of robustness and adaptability that can be difficult to achieve in rigid-body\, motor-driven devices. However\, with the physical advantages of these versatile actuators come significant challenges in sensing\, feedback control\, and sustainable\, portable powering that can limit their feasibility in real-world applications. This talk will highlight the engineering challenges of pneumatic actuation within the context of ongoing robotics research efforts in the ARM Lab\, including the development of a soft\, EMG-controlled robotic knee exoskeleton. The implications of new pneumatic actuation approaches on the future of smart\, wearable human augmentation systems will also be discussed.

SUMMARY:PICS Colloquium: "Kinetic theory for superparameterization of sea ice dynamics"
DESCRIPTION:Arctic sea ice comprises of many ice floes whose dynamics is driven by oceanic/atmospheric currents and floe-floe interaction. Models of the effective sea ice dynamics  at large scales typically employ hydrodynamic equations of motion\, such as mass and momentum conservation\, with complex constitutive laws attempting to capture the rheology of sea ice as a continuum. Although hydrodynamic sea ice models have enjoyed some successes\, they have well-documented limitations in capturing phenomena such as fracture and lead formation\, which are direct manifestation of the granular nature of sea ice. \nIn this talk\, we describe a framework that generalizes hydrodynamic models for sea ice using a mesoscopic (kinetic) description that systematically couples macro-scale PDEs with small-scale particle methods. This framework employs a time-dependent probability distribution over floe position and velocity\, evolving according to the Boltzmann equation. The mass density and momentum (computed by integrating over the velocity coordinate) evolve according to the same macro-scale hydrodynamic equations used in previous models. However\, rather than requiring an effective rheology\, kinetic models of the collisions between co-located ice particles determine the small-scale evolution of the conditional density and influence the macro-scale dynamics. To simulate this system efficiently\, we construct a two-tiered numerical method that employs finite element methods to solve the macro-scale PDEs and a particle method to evolve the conditional density over the velocity coordinate. We illustrate the framework with idealized numerical experiments demonstrating that it can naturally reproduce phenomena such as ice breakup under a divergent flow.

SUMMARY:CBE PhD Dissertation Defense | “Process Development and Modeling for the Advancement of Direct Air Capture Technologies"
DESCRIPTION:Abstract: \n“As the catastrophic effects of climate change are felt throughout our global society\, we must take immediate action. A portfolio of climate solutions must include both deep and robust decarbonization\, and systems to remove carbon dioxide directly from the atmosphere. One promising suite of carbon removal technologies is Direct Air Capture (DAC). DAC refers to engineered systems that pull CO2 from air\, capturing it in a near-pure form. The captured CO2 can be stored geologically (resulting in a reduction of atmospheric CO2 concentrations)\, or otherwise utilized. This Dissertation focuses on development and deployment of DAC technologies first by exploring the current DAC landscape\, then by proposing a novel DAC process using earth-abundant minerals. \n\nThe current landscape of DAC includes two main approaches: solid sorbent and liquid solvent. Each DAC approach has advantages and challenges\, including energy usage\, specialty chemical demand\, and land area requirements. Here\, each approach is outlined\, and suggestions are provided to accelerate industrial deployment. Additionally\, the effect of different dedicated energy infrastructure to power solvent-based DAC is evaluated\, including both fossil and renewable energy resources and quantifying the effect of energy-related emissions on the amount of carbon net removed from air. A technoeconomic tool is also presented which allows for a high-level cost estimate of DAC based on available information. The tool can be utilized by investors to evaluate key aspects of DAC technologies and determine which innovations result in significant cost reductions. \n\nAn ambient oxide looping process is proposed as a novel approach to DAC. The process uses earth-abundant minerals (limestone\, magnesite) to produce reactive oxides (calcium oxide\, magnesium oxide) that react with the CO2 in air. Investigation into the economics of the process indicates it could be less expensive per ton of CO2 removed than other DAC technologies. To understand the process viability\, a series of experiments characterize industrially available calcium and magnesium oxide and hydroxide feedstocks. These experiments probe the physical properties of these materials and different aspects of engineering optimization\, including material depth and rate enhancement as a function of both relative humidity and direct water addition to the system. “

SUMMARY:MEAM Seminar: “Robotics Goes Soft: Challenges and Achievements\, for New Robotics Scenarios”
DESCRIPTION:Largely inspired by the observation of the role of soft tissues in living organisms\, the use of soft materials for building robots is recognized as one of the current challenges for pushing the boundaries of robotics technologies and building robotic systems for service tasks in natural environments. The study of living organisms sheds light on principles that can be fruitfully adopted to develop additional robot abilities or to facilitate more efficient accomplishment of tasks\, because living organisms exploit soft tissues and compliant structures to move effectively in complex natural environments. \nWidely growing worldwide\, soft robotics has produced already interesting achievements in terms of technologies for actuation\, sensing\, control\, and many more. In addition to allowing more applications for robots\, soft robotics technologies are enabling robot abilities that were not possible before\, like morphing\, stiffening\, growing\, self-healing\, evolving. They open up new scenarios for robotics that brings towards more life-like robots\, effectively and efficiently adaptable to their environments and tasks.

SUMMARY:Fall 2021 GRASP SFI: “Physics-inspired learning for discontinuous contact dynamics”
DESCRIPTION:*This will be a HYBRID Event with in-person attendance in Levine 307 and Virtual attendance via Zoom here… \nFrictional contact is the core underlying behavior of robot locomotion and manipulation\, and its nearly-discontinuous dynamics make planning and control challenging even when an accurate model of the robot is available. In this talk\, I will first present empirical evidence that learning an accurate model in the first place can be confounded by contact\, as modern deep learning approaches are not designed to capture this non-smoothness. Second\, I will discuss ContactNets\, our approach which circumvents this conflict via a smooth\, implicit encoding of discontinuity as signed distance functions and contact-frame Jacobians.

SUMMARY:ESE Fall Colloquium Seminar  - "Transforming Ideas to Reality: Emerging Nanotechnologies from the “Lab” to the “Fab”"
DESCRIPTION:Emerging nanotechnologies promise to enable a wide-range of next-generation applications – from energy-efficient computing to personalized healthcare. Yet many emerging nanotechnologies face substantial inherent imperfections and variations that have rendered making working systems – and therefore the next-generation applications they promise to enable – infeasible. In this talk\, I will describe how by computing advances across the entire stack – from nanomaterial synthesis to new processing techniques\, circuit design methodologies\, architectures\, and novel systems – these challenges can be overcome to realize the first large-scale and complex electronic systems leveraging beyond-silicon emerging nanotechnologies. As a case-study\, I will describe the journey of transforming carbon nanotubes from an interesting scientific nanomaterial in academic labs into the foundation for realizing novel systems and applications that can impact our daily lives\, such as the first beyond-silicon microprocessor for energy-efficient computing and novel diagnostic tools for rapid and accurate disease diagnostics. I will conclude by describing how these emerging nanotechnologies are currently being transferred from the “lab” to multiple commercial “fabs”\, promising a new and exciting age for electronics and the systems and applications they can enable.

SUMMARY:MSE Grace Hopper Lecture: "Optics on the Nanoscale: Conquering Absorption with Nonlinear Optics"
DESCRIPTION:Optical nanostructures enable molding the flow of light on the subwavelength scale rendering possible the realization of compact\, cost-effective\, flat and highly efficient optical components for imaging\, spectroscopy\, sensing\, and communications. From the fundamental science viewpoint\, light-matter interactions at the nanoscale reveal themselves in new and often unexpected ways. In fact\, the usual linear and nonlinear macroscopic theories that describe the behavior of the electromagnetic field merit revision. From the applications viewpoint\, miniaturized\, tunable and reconfigurable functionalities implemented on a chip are of paramount importance. Here\, we reassess dielectric materials such as chalcogenides as promising candidates for science and applications in wavelength ranges once thought to be hostile to the propagation of light. We show that\, in fact\, these materials constitute new\, excellent contenders for developing new\, multi-functional nanophotonic devices due to their high linear refractive indices\, strong nonlinear response\, and fast switching speeds. To date\, applications of these glasses have been limited to wavelength ranges where absorption meticulously avoided\, for example\, above 500nm for As2S3: high absorption at visible and ultraviolet wavelengths manifests itself through the large imaginary parts of the dielectric constants. However\, we demonstrate that\, as counterintuitive as it may appear\, highly nonlinear\, properly nanostructured chalcogenide glass\, transparent in the mid- and near-infrared\, can also be used to generate third harmonic frequencies in the visible and ultraviolet part of the spectrum\, despite the presence of strong material absorption in this range. Such third-harmonic generation can be tuned and further enhanced using stacked metasurfaces and various mechanisms of local field enhancement\, including Mie and quasi-bound states in continuum resonances.

SUMMARY:BE Seminar: "Systems-level Analyses of the Human Gut Microbiome" (Ilana Lauren Brito)
DESCRIPTION:This seminar will be held live and broadcast on zoom – check your email for the link or contact ksas@seas.upenn.edu. \nA major question regarding the human gut microbiota is: by what mechanisms do our most intimately associated organisms affect human health? In this talk\, I will present several systems-level approaches that we have developed to address this fundamental question. My lab has pioneered methods that leverage protein-protein interactions to implicate bacterial proteins in human pathways linked to disease\, revealing for the first time a network of interactions that affect diseases such as colorectal cancer\, inflammatory bowel disease\, type 2 diabetes and obesity that can be mined for novel therapeutics and therapeutic targets. I will present novel methods that that enable deeper insight into the transcriptome of organisms within our guts and their spatial localization. Finally\, I will shift to the problem of the spread of antibiotic resistance\, in which the gut microbiota are implicated. Pathogens become multi-drug resistance by acquiring resistance traits carried by the gut microbiota. Studying this process in microbiomes is inherently difficult using current methods. I will present several methods that enable tracking of genes within the microbiome and computational tools that predict the network of gene transfer between bacteria. Overall\, these systems-level tools provide deep insight into the knobs we can turn to engineer outcomes within the microbiome that can improve human health.

SUMMARY:GRASP on Robotics: "Planning on Graphs of Convex Sets"
DESCRIPTION:*This will be a HYBRID Event with in-person attendance in Wu & Chen Auditorium and Virtual attendance via Zoom Webinar here.  \nMotivated by the challenging problems in planning and control through contact\, our group has been working to connect more deeply the motion planning formulations we often use in robotics with a different lineage of algorithms and results in combinatorial optimization. What we’ve found surprised me: I feel that we’ve been formulating our mixed-integer motion planning problems incorrectly\, and that there are better formulations that can lead to dramatically faster solve times and tighter convex relaxations. I’d like to tell you that story\, through the lens of optimization-based collision-free motion planning. This is joint work with Tobia Marcucci\, Jack Umenberger\, and Pablo Parrilo. I’ll also briefly describe a few other ongoing projects in robotic manipulation\, and promise to show some robot videos.

SUMMARY:PICS Colloquium: "A model for external aerodynamics based on building-block flows"
DESCRIPTION:Abstract: A wall model for large-eddy simulation is proposed by devising the flow as a collection of building blocks\, whose information enables the prediction of the stress as the wall.  The core assumption of the model is that simple canonical flows (such as turbulent channel flows\, boundary layers\, pipes\, ducts\, speed bumps\, etc) contain the essential flow physics to devise accurate models. Three types of building block units are used to train the model\, namely\, turbulent channel flows\, turbulent ducts\, and turbulent boundary layers with separation.  The approach is implemented using two interconnected artificial neural networks: a classifier\, which identifies the contribution of each building block in the flow; and a predictor\, which estimates the wall stress via non-linear combinations of building-block units. The output of the model is accompanied by the confidence in the prediction. The latter aids the detection of areas where the model underperforms\, such as flow regions that are not representative of the building blocks used to train the model. The model is validated in a realistic aircraft geometry from NASA Juncture Flow Experiment\, which is representative of external aerodynamic applications with trailing-edge separation.

SUMMARY:CBE PhD Dissertation Defense | “3D-stiffness Microenvironment Leads to Nuclear Envelope Rupture\, DNA Damage\, and Genome Variation”
DESCRIPTION:Abstract: \n“Solid tumor cells grow in a stiff microenvironment with dense extracellular matrix (ECM) and condensed packing of adjacent cells. Tumor cells are capable of migrating through constricted pores formed by ECM or surrounded by other cells\, and the nuclear envelope can break with repair factor mislocalization\, further leading to DNA damage and genetic changes\, or even accumulated to be genomic variations. Cell division\, likewise\, is confined by a stiff niche of adjacent cells and extracellular matrix\, and such confinement has been reported to cause chromosome mis-segregation. The chromosome-loss live cell reporter system was developed to prove that cells undergoing specific types of chromosome missegregation can survive and maintain heritability\, resulting in permanent genomic variations. Mitotic cells under in vitro confinement and in vivo conditions exhibit more abnormal division and more fluorescence-null reporter-negative cells\, for both cancer and normal types. Confinement and SAC inhibition both lead to chromosome mis-segregation but do not superimpose\, and Topoisomerase IIa plays an essential role in cells to survive after confined mitosis. Myosin II was found to lead to increased nuclear envelope rupture and\, therefore\, more DNA damage\, while it protects mitotic cell rounding within 3D confined environments\, since the increase of reporter-negative cells was observed after Myosin II knockdown. “

SUMMARY:MEAM Seminar: "Designing Robotic Systems with Collective Embodied Intelligence"
DESCRIPTION:Natural swarms exhibit sophisticated colony-level behaviors with remarkable scalability and error tolerance. Their evolutionary success stems from more than just intelligent individuals\, it hinges on their morphology\, their physical interactions\, and the way they shape and leverage their environment. Mound-building termites\, for instance\, are believed to use their own body as a template for construction; the resulting dirt mound serves\, among other things\, to regulate volatile pheromone cues which in turn guide further construction and colony growth. Throughout this talk I will argue how we can leverage the same principles to achieve greater performance in robot collectives\, by paying attention to the interplay between control and hardware\, as well as direct- and environmentally-mediated coordination between robots. I will exemplify the strength and challenges of this approach through cell-inspired\, soft\, single- and multi-robot systems for exploration; micro-scale robots for bio-medical applications; termite-inspired multi-robot systems for construction- and excavation; and bio-hybrid systems for agricultural monitoring.

SUMMARY:ESE Grace Hopper Lecture  - "A Communications Perspective on Digital Privacy"
DESCRIPTION:Many of the activities in cyberspace\, from social networking to the use of mobile apps\, leave digital footprints compromising the users’ privacy.  As digital tracking technologies become more sophisticated and pervasive\, there is a need to understand and quantify the users’ privacy risk\, that is\, what is the likelihood that users in cyberspace can be uniquely identified from their activities? \nIn this talk\, we focus on de-anonymization attacks\, where publicly and privately available information about users\, represented as connectivity graphs\, are leveraged to compromise user identities. We model the de-anonymization attack as a graph matching  problem in which  we have two correlated stochastic graphs the first of which has labeled vertices\, whereas the second one is unlabeled. The goal is to recover the labels of the second graph by using the correlation structure. We explore how graph matching can be posed as a communications problem\, and tools from information theory\, communication theory and probability can be used to derive theoretical guarantees and algorithms for graph matching\, thereby providing a framework for quantifying the privacy risk of users in the cyberspace.
