SUMMARY:CIS Seminar: "Towards a New Synthesis of Reasoning and Learning"
DESCRIPTION:This talk discusses the role of logical reasoning in statistical machine learning. While their unification has been a long-standing and crucial open problem\, automated reasoning and machine learning are still disparate fields within artificial intelligence. I will describe recent progress towards their synthesis in three facets.\nI start with a very practical question: how can we enforce logical constraints on the output of deep neural networks to incorporate symbolic knowledge? Second\, I explain how circuits developed for tractable logical reasoning can be turned into statistical models. When brought to bear on a variety of machine learning tasks\, including discrete density estimation and simple image classification\, these probabilistic and logistic circuits yield state-of-the-art results. In a third facet\, I argue for high-level representations of uncertainty\, such as probabilistic programs\, probabilistic databases\, and statistical relational models. These pose unique challenges for inference that can only be overcome by high-level reasoning about their first-order structure to exploit symmetry and exchangeability.

SUMMARY:MEAM Seminar: "Integrating Manufacturing and Topological Optimization for the Design of Architected Materials and Components"
DESCRIPTION:Topology optimization has long been touted as a powerful tool capable of discovering innovative solutions to engineering design problems. It has been used to design ‘structures’ characterized at a range of length scales\, from tens of microns (material architectures) to decameters (structures)\, for performance properties governed by a range of physics. Despite its tremendous potential as a design tool\, topology optimized solutions are typically suboptimal when considering real-world operating conditions\, design objectives\, and manufacturing processes\, and thus may require significant post-processing and re-design which is both detrimental and time consuming. This talk will review the topology optimization methodology and discuss our efforts at overcoming these shortcomings\, with a particular emphasis on providing the design engineer geometric control to enable design for manufacturability. Several design examples will be presented including architected materials\, components and devices that are fabricated through additive manufacturing\, machining or 3D weaving\, and optimized for mechanical\, fluidic\, and/or thermal properties.

SUMMARY:BE Grace Hopper Lecture: Powering tumor cell migration through heterogeneous microenvironments
DESCRIPTION:To move through tissues\, cancer cells must navigate a complex\, heterogeneous network of fibers in the extracellular matrix.  This network of fibers also provides chemical\, structural and mechanical cues to the resident cells.  In this talk\, I will describe my lab’s efforts to understand the forces driving cell movements in the tumor microenvironment.  Combining tissue engineering approaches\, mouse models\, and patient samples\, we create and validate in vitro systems to understand how cells navigate the tumor stroma environment. Microfabrication and native biomaterials are used to build mimics of the paths created and taken by cells during metastasis. Using these platforms\, we have described a role for a balance between cellular energetics\, cell and matrix stiffness\, and confinement in determining migration behavior. Moreover\, we have extended this work into investigating the role of the mechanical microenvironment in tumor angiogenesis to show that mechanics guides vessel growth and integrity. I will discuss the mechanical influences at play during tumor progression and the underlying biological mechanisms driving angiogenesis and metastatic cell migration as a function of the ECM with an eye towards potential therapeutic avenues.

SUMMARY:CIS Seminar: "Making Parallelism Pervasive with the Swarm Architecture"
DESCRIPTION:Abstract: \nParallelism is critical to achieve high performance in modern computer systems. Unfortunately\, most programs scale poorly beyond a few cores\, and those that scale well often require heroic implementation efforts. This is because current architectures squander most of the parallelism available in applications and are too hard to program. \nI will present Swarm\, a new architecture that exploits far more parallelism than conventional multicores and is almost as easy to program as a sequential thread. Swarm programs consist of tiny tasks\, as small as tens of instructions each. Synchronization is implicit: the programmer specifies a total or partial order on tasks. This eliminates the correctness pitfalls of explicit synchronization (e.g. deadlock and data races). Swarm hardware uncovers parallelism by speculatively running tasks out of order\, even thousands of tasks ahead of the earliest active task. Its speculation mechanisms build on decades of prior work\, but Swarm is the first to scale to hundreds of cores due to its new programming model\, distributed structures\, and distributed protocols. Swarm also incorporates new techniques to reduce data movement\, harness nested parallelism\, and combine speculative and non-speculative parallelism. \nSwarm achieves efficient near-linear scaling to hundreds of cores on challenging irregular applications. These span a broad set of domains\, including graph analytics\, machine learning\, databases\, simulation\, and more. Swarm even accelerates applications that are often deemed sequential. It outperforms state-of-the-art software-only parallel algorithms by one to two orders of magnitude\, and sequential implementations by up to 600x at 256 cores.

SUMMARY:MEAM Seminar: "Additive Manufacturing and Architected Materials"
DESCRIPTION:Material properties are governed by the chemical composition and spatial arrangement of constituent elements. Over the past decade\, the field of architected materials has sought to design\, fabricate\, and demonstrate materials with performance that is fundamentally controlled by geometry at multiple length-scales rather than chemical composition alone. There have been many advancements ranging from the maturation of additive manufacturing technologies which can be used to realize these materials\, to inverse design methods such as topology optimization\, and even includes unique new material feedstocks which make up the structures. This presentation will touch on all aspects of the architected materials realization process as well as evaluate performance of some of those materials. Specifically\, we have demonstrated designer properties of these architected materials in polymers\, metals\, ceramics and combinations thereof. In addition to novel properties such as ultra-stiff lightweight materials\, negative stiffness\, and negative thermal expansion\, I will present multifunctional architected materials with energy storage capability and architectures that respond to external fields. Many of these architected materials derived from advanced design and optimization methods which we have been developing and were fabricated with custom additive manufacturing techniques. These include projection microstereolithography (PµSL)\, direct ink writing (DIW)\, electrophoretic deposition (EPD)\, volumetric additive manufacturing (VAM)\, computed axial lithography (CAL)\, and diode-based additive manufacturing (DiAM) to name a few. New materials including graphene aerogel\, carbon fiber composites\, and printed glass will also be touched upon.

SUMMARY:CIS Seminar: "Towards Human-Level Recognition via Contextual\, Dynamic\, and Predictive Representations"
DESCRIPTION:Abstract:\n\nExisting state-of-the-art computer vision models usually specialize in single domains or tasks\, while human-level recognition can be contextual for diverse scales and tasks. This specialization isolates different vision tasks and hinders deployment of robust and effective vision systems.  In this talk\, I will discuss contextural image representations for different scales and tasks through the lens of pixel-level prediction. These connections\, built by the study of dilated convolutions and deep layer aggregation\, can interpret convolutional network behaviors and lead to model frameworks applicable to a wide range of tasks. Beyond contextual\, I will argue that image representation should also be dynamic and predictive. I will illustrate the case with input-dependent dynamic networks\, which lead to new insights into the relationship of zero-shot/few-shot learning and network pruning\, and with semantic predictive control\, which utilizes prediction for better driving policy learning. To conclude\, I will discuss the on-going system and algorithm investigations which couple representation learning and real-world interaction to build intelligent agents that can continuously learn from and interact with the world.

SUMMARY:ESE Seminar: "Safety and Robustness Guarantees with Learning in the Loop"
DESCRIPTION:In this talk\, we present recent progress towards developing learning-based control strategies for the design of safe and robust autonomous systems. Our approach is to recognize that machine learning algorithms produce inherently uncertain estimates or predictions\, and that this uncertainty must be explicitly quantified (e.g.\, using non-asymptotic guarantees of contemporary high-dimensional statistics) and accounted for (e.g.\, using robust control/optimization) when designing safety critical systems. We focus on the safety constrained optimal control of unknown systems\, and show that by integrating modern tools from high-dimensional statistics and robust control\, we can provide\, to the best of our knowledge\, the first end-to-end finite data robustness\, safety\, and performance guarantees for learning and control. We further show how this approach can be incorporated into an adaptive polynomial-time algorithm with non-asymptotic convergence rate (regret bound) guarantees. As a whole\, these results provide a rigorous and contemporary perspective on safe reinforcement learning as applied to continuous control. We conclude with our vision for a general theory of safe learning and control\, with the ultimate goal being the design of robust and high performing data-driven autonomous systems.

SUMMARY:CIS Seminar: "Improving Security at an Internet Scale: A Data-Driven Approach"
DESCRIPTION:The state of security across the Internet is poor\, and it has been so for years. Meanwhile\, attacks have become ever more frequent and consequential. How do we actually make meaningful progress? To do so\, we must move beyond the folklore that heavily influences Internet security practices today\, and establish 1) empirical grounding on how and why security problems manifest the way they do across the Internet\, and 2) data-driven methods for improving security at an Internet scale. \n  \nIn this talk\, I will describe my evidence-based and holistic approach to security\, illustrated by my work on improving how we remedy security problems (vulnerabilities\, misconfigurations\, and compromise incidents) for Internet systems. Using a variety of empirical methods\, including Internet-wide network measurements\, user studies\, machine learning\, and code analysis\, my research systematically identifies how security is managed for Internet systems\, factors that contribute to continued vulnerability\, and barriers that prohibit the effective remediation of security concerns. Informed by insights from this work\, I develop methods and systems for more effective remediation at an Internet scale.

SUMMARY:BE Seminar Series: Heterogeneous\, Multi-Scale and Patient-Speci C Pharmacodynamic Systems Models for Cancer with Clinical Applications
DESCRIPTION:Abstract: Systems models of key signaling pathways in cancer have been extensively used to understand and explore the mechanisms of action of drugs and growth factors on cancer cell signaling. In general\, such models predict the effect of mechanical or chemical stimuli (for e.g. drug dosage) in terms of activity of one or more key downstream proteins such as ERK or AKT which are important regulators of cell fate decisions. Although such models are greatly useful and have helped uncover important emergent properties of signaling networks such as ultrasensitivity\, bistability and oscillations\, they miss many key features that would make them useful in a clinical setting. \n1) The predictions of activity of proteins such as ERK or AKT cannot be directly translated into a clinically useful cell fate parameter such as cell kill rate. \n2) They don’t work as well when there are multiple biological processes operating under different time and length scales such as receptor based signaling (4-6 hours) and cell cycle (24-48 hours). \n3) They cannot incorporate important cellular physics like mechanics of the cell membrane\, ECM and the cytoskeleton. \n4) The parameter space of such models often exhibits sloppy/stiff character which affect the accuracy of predictions and the robustness of these models.  Such analysis are often not done which casts doubt on validity of the predictions. \nHere we have developed a multiscale and multiparadigm framework for systems and pharmacodynamic models that helps us address some of the above shortcomings. This framework was used to successfully integrate a single-cell systems model of ErbB receptor mediated Ras-MAPK and PI3K/AKT pathway with tumor suppressor p53 mediated DNA damage response and cell cycle pathway. The integrated model was used in a clinical setting using gene/protein expression data and drug dosage/schedule information from actual patients of prostate adenocarcinoma. Special mathematical techniques were used to develop algorithms that can integrate models of disparate time scales and time resolutions (continuous vs. discrete time).

SUMMARY:BE Seminar Series: Synchronization is Robust in a Computational Model of Neuronal Network Dynamics and Injury
DESCRIPTION:At the macroscale\, synchronization between brain regions is believed to be important for memory and attention. Injury\, including mild traumatic brain injury\, can both increase and decrease synchronization as measured by functional MRI\, but these changes are not well understood and are unknown at a smaller spatial scale. Here\, we examined how injury affects the synchronization between two clusters of neurons. We used a computational network model consisting of excitatory and inhibitory neurons\, derived from Izhikevich integrate-and-fire neurons. We connected two clusters of neurons with different intrinsic firing rates. In this architecture\, two distinct clusters of neurons were directionally connected from one upstream cluster to one downstream cluster. The network remodeled according to the rules of spike-timing-dependent plasticity (STDP)\, resulting in highly synchronized activity between the clusters. We characterized structural subtypes within the network and subsequently explored the functional effects of damaging the network by removing neurons based on their subtype membership.

DESCRIPTION:Though rooted in pure mathematics\, algebraic topology has recently enabled novel analysis techniques for biological data. Specifically\, the method called persistent homology which employs ideas from topology to characterize the voids in a complex network. In this talk\, I will briefly introduce persistent homology and give an overview of how we have recently applied this tool to answer questions in neuroscience and semantic learning. Finally\, I will provide additional examples of topology in biology and suggest how current research in pure algebraic topology may soon aid in our understanding of complex systems.

SUMMARY:ESE Seminar: "Control of Light and Heat for New Energy Applications"
DESCRIPTION:Light carries energy and heat\, and plays a key role in many energy-conversion processes. The capabilities\nto tailor electromagnetic energy transfer at the nanoscale represent important opportunities for novel\nenergy applications. In this talk I will present two sets of studies integrating experiments and theory. In\nthe first part\, I will discuss how to use near field electromagnetic energy transfer for energy conversion\nand photonic refrigeration. I will begin by showing an experiment achieving a 40-fold enhancement of\nthermophotovoltaic conversion rates\, by reducing the distance between a thermal emitter and a\nphotovoltaic cell to the nanoscale. This lays the foundation for exploring near-field thermophotovoltaics\nfor waste heat recovery. I will then show a demonstration of active photonic refrigeration through control\nof the chemical potential of photons. This points to a fundamentally new\, promising way for solid state\nrefrigeration by combining nanoscale photonics and optoelectronics.\nIn the second part\, I will discuss how to turn the cold outer space to a thermodynamic resource for passive\ncooling and energy efficiency. I will introduce our first demonstration of passive radiative cooling to\nbelow the ambient air temperature under direct sunlight. Next I will show an experiment achieving\npassive cooling to 42 ˚C below the ambient temperature\, pointing to new regimes of applications such as\nfood preservation in remote areas. I will also show results of lowering the temperature of a solar absorber\nby 13 ˚C while maintaining the sunlight absorption\, pointing to significant efficiency improvement for\nsolar cells. Finally\, I will give an overview of my future research directions.

SUMMARY:CIS Seminar: "Computer Security for Emerging Technologies"
DESCRIPTION:As our world becomes more computerized\, security and privacy takes on a prominent role in allowing us to enjoy the benefits of new technologies without the risks. Addressing the new challenges that come with this role requires a change in how we approach and solve problems in computer security. My vision is that we must view computer security as a whole-system property ranging from the physical-layer right up to applications and end-users. In line with this vision\, my approach to computer security involves formulating the right security problem to work on\, addressing design-level issues by constructing strong defenses at the appropriate layer of abstraction\, and challenging common assumptions to understand realistic threats. In this talk\, I will give several examples of my approach and vision\, focusing on emerging technologies that span the digital-to-physical interface. I will cover technical results at various level of abstraction\, including analysis techniques that found exploitable design-level vulnerabilities in closed-source smart home platforms\, a new design for trigger-action platforms that provides strong integrity guarantees\, and an analysis of how realistic attacks on machine learning can occur in the physical world. Finally\, I will share my vision of the future of security and privacy research in an increasingly connected world.

SUMMARY:MEAM Seminar: "Force\, Shape\, and Motion in Collective Cell Migration"
DESCRIPTION:Cells migrate collectively to form tissues\, to heal wounds\, and\, in cancer\, to metastasize. During these biological processes\, the collective migration exhibits a transition from a solid-like state\, wherein cell positions remain fixed\, to a fluid-like state\, wherein cells flow freely and rearrange their positions with their neighbors. Recent mechanics-based models and experiments have demonstrated that this transition can be predicted by average cell shape\, with cells having more elongated shapes and greater perimeters more easily sliding past their neighbors. At each cell-cell interface\, it has been proposed that active actomyosin contraction generated within the cell cortex acts as an effective surface tension tending to reduce each cell’s perimeter. Cell-cell adhesions have the opposite effect\, tending to reduce the surface tension\, thereby increasing the perimeter. It is unclear how cells regulate these competing factors in a confluent monolayer. This presentation will describe our investigation of the factors affecting cell surface tension and cell perimeter\, and the corresponding effects on collective migration. Our experiments use monolayers of Madin-Darby Canine Kidney cells and quantify cell forces\, shapes\, and motion. With this experimental data\, we test the theoretical predictions relating cell shape and motion.

SUMMARY:CIS Seminar: "Machine Learning: Why Do Simple Algorithms Work So Well?"
DESCRIPTION:While state-of-the-art machine learning models are deep\, large-scale\, sequential and highly nonconvex\, the backbone of modern learning algorithms are simple algorithms such as stochastic gradient descent\, or Q-learning (in the case of reinforcement learning tasks). A basic question endures—why do simple algorithms work so well even in these challenging settings?\n\nThis talk focuses on two fundamental problems: (1) in nonconvex optimization\, can gradient descent escape saddle points efficiently? (2) in reinforcement learning\, is Q-learning sample efficient? We will provide the first line of provably positive answers to both questions. In particular\, we will show that simple modifications to these classical algorithms guarantee significantly better properties\, which explains the underlying mechanisms behind their favorable performance in practice.

SUMMARY:CIS Seminar: " Natural language to structured knowledge representations"
DESCRIPTION:Computing machinery such as smartphones are ubiquitous\, and so will be smart home appliances\, self-driving cars and robots in the near future. Enabling these machines with natural language understanding abilities opens up potential opportunities for the broader society to benefit from\, e.g.\, in accessing the world’s knowledge\, or in controlling complex machines with little effort.\n\nIn this talk\, we will focus on accessing knowledge stored in knowledge-bases and text documents in a colloquial manner. We will do so by processing language into programs that perform reasoning. The main questions we will explore are 1) which inductive biases on neural architectures are well suited for processing language to programs? 2) what is the role of linguistic structure? and 3) can we build models which produce answers without generating an explicit program?

SUMMARY:CIS Seminar: "Security for All: Modeling Structural Inequities to Design More Secure Systems"
DESCRIPTION:Users often fall for phishing emails\, reuse simple passwords\, and fail to effectively utilize “provably” secure systems. These behaviors expose users to significant harm and frustrate industry practitioners and security researchers alike. As consequences of security breaches become ever more grave\, it is important to study why humans behave seemingly irrationally. In this talk\, I will illustrate how modeling the effects of structural inequities — variance in skill\, socioeconomic status\, as well as culture and gender identity — can both explain apparent irrationality in users’ security behavior and offer tangible improvements in industry systems. Modeling and mitigating security inequities requires a combination of techniques from economic\, data scientific\, and social science methodologies to develop new tools for systematically understanding and mitigating insecure behavior. \nThrough novel experimental methodology\, I empirically show strong evidence of bounded rationality in security behavior: Users make mathematically modelable tradeoffs between the protection offered by security behaviors and the costs of practicing those behaviors\, which even in a highly usable system may outweigh the benefits\, especially for less resourced users. These findings emphasize the need for industry systems that balance structural inequities and accommodate behavioral variance between users rather than one-size-fits-all security solutions. More broadly\, my techniques for modeling and accounting for inequities have offered key insights in growing technical areas beyond security\, including algorithmic fairness.

SUMMARY:MEAM Seminar: "Nanoparticle Heating for Therapeutics\, Regenerative Medicine and Diagnostics"
DESCRIPTION:Gold and iron oxide nanoparticles have unique and tunable properties that allow transduction of optical (light)\, or radiofrequency (RF) electromagnetic fields to affect heating of biomaterials at multiple scales. This talk will explore the underlying physics and relative advantages of each form of nanoparticle heating for therapeutic treatment of cancer or other disease by heating (i.e. magnetic hypothermia or photothermal cancer therapy). In addition\, this same heating helps improve regenerative medicine by “nanowarming” vitrified (i.e. cryopreserved) biomaterials back to a transplantable state through rapid and uniform warming that avoids crystallization and cracking. This nanoparticle warming addresses an important technology bottleneck for both large systems (i.e. tissues and organs) and smaller systems (i.e. embryos and oocytes). In summary\, this talk demonstrates the growing opportunites for nanoparticle heating in biomedical applications.

SUMMARY:PICS Seminar: "Coupled Multiphysics Models of Cardiac Hemodynamics: From Fundamental Insights to Clinical Translation"
DESCRIPTION:  \n\n\nAbstract: The mammalian heart has been sculpted by millions of years of evolution into a flow pump par excellence. During the typical lifetime of a human\, the heart will beat over three billion times and pump enough blood to fill over 60 Olympic-sized swimming pools. Each of these billions of cardiac cycles is itself a manifestation of a complex and elegant interplay between several distinct physical domains including electrophysiology and mechanics of the cardiac muscles\, hemodynamics\, and flow-induced movement of the cardiac valves. Another multiphysics interaction that is key to hemostasis involves hemodynamics and blood biochemistry. The clotting cascade\, which is a natural response to injury\, is initiated by a sequence of biochemical reactions that are strongly modulated by the local flow conditions. In this regard\, how the chambers and valves of a healthy heart manage to avoid thrombosis\, remains an open question. The presence of heart conditions such as myocadial infarction (MI)\, cardiomyopathies\, valve anomalies and atrial fibrillations\, disturb the hemostatic balance and can lead to thrombosis with devastating sequalae such as stroke and MI. Computational models for thrombogenesis in the cardiac system have the potential to provide useful insights into this important phenomenon. In the current talk\, I will describe high-fidelity chemo-fluidic modeling of thrombogenesis in the left heart and demonstrate how fundamental insights from these studies are translated into clinically relevant metrics. Application of these models to thrombogenesis in transcatheter aortic valves will also be described.

SUMMARY:ESE Seminar: "Confluence of Electromagnetics\, Circuits and Systems Enables The Third Wireless Revolution"
DESCRIPTION:Integrated circuits have fueled several revolutions that have deeply impacted modern society\, including the computing revolution\, the internet and the first two wireless revolutions. We are at the dawn of the third wireless revolution\, which I call the Wireless Mobile Reality revolution. Over the next fifteen years\, new wireless paradigms spanning from radio frequencies to millimeter-waves and terahertz will change the way in which we interact with the real world\, through applications such as mobile virtual and augmented reality\, vision quality imaging\, gesture recognition and bio- and materials-sensing. \nHowever\, at the same time\, integrated circuits are starting to run out of steam – technology scaling is no longer yielding better transistors that are faster and lower power. Therefore\, circuit design needs to be refreshed with new tools and techniques that draw inspiration from the layers below (electromagnetics and device physics) and the layers above (communication systems and networking). \nIn this talk\, I will describe research along these lines from the CoSMIC lab at Columbia University. I will start by describing a new approach to breaking Lorentz reciprocity to engineer high-performance non-reciprocal components\, such as gyrators\, isolators and circulators. I will then talk about how these integrated non-reciprocal circulators enable practical integrated full-duplex wireless radios. Finally\, I will talk about the FlexICoN project at Columbia which is taking a holistic and cross-layer view of full-duplex networks from the physical layer to the networking layer. I will also briefly touch upon other work from CoSMIC lab in the same vein related to high-power\, high-efficiency millimeter-wave radios\, MIMO radios\, opto-electronic LIDARs and city-scale wireless testbeds.
