SUMMARY:MEAM Seminar: "Breaking Bones In situ: Multiscale Bioinspired Functional Materials"
DESCRIPTION:In structural materials engineering\, we often aim to create materials that are simultaneously strong\, tough and lightweight- a combination classically considered mutually exclusive. Biogenic composite materials such as bone exhibit a combination of these properties exceeding that of their constituents\, a feat generally credited to their hierarchal structure\, down to the nanoscale. In this talk\, we will demonstrate the use of micro and nanoscales site-specific microstructural characterization and mechanical experiments to probe the strength\, deformation\, and fracture behavior of human bone. We will demonstrate an in situ SEM/nanoindentor methodology\, that enables 3-point bending fracture experiments with observation and measurement of crack growth and toughening behavior at nano and micrometer scales. We will discuss the crack (1 initiation and growth mediated underlying fibril microstructure (~50 nm) in bone and place it in the context of hierarchical toughening up to the macro/organ level (500+ um) fracture. We will use generalized lessons learned about biogenic materials to discuss additive manufacturing of metals. We will explore how we can leverage of the unique processing conditions and tunability of nanoparticle functionalized feedstock in metal additive manufacturing to control microstructure\, as well as expand the library of currently “printable” materials for potential applications ranging from biomedical to thermal.

SUMMARY:ESE Seminar: "Integrated Nonlinear and Quantum Photonic Devices"
DESCRIPTION:Recent advances in nanofabrication technology have allowed for the realization of ultra-low loss nanophotonic waveguides and is opening up exciting opportunities for next-generation nonlinear photonic circuits with higher integration density\, advanced functionalities\, and ultralow energy consumption. Those features are critical for advancing photonic technologies in both classical and quantum domains. \nIn this talk\, I will discuss silicon-based and thin-film lithium niobate (LN)-based photonic devices\, which leverage the combination of Kerr and second-order nonlinearities\, along with electro-optic (EO) and piezoelectric effects to achieve highly efficient and controllable light-matter interactions with optical\, electrical\, or mechanical waves at extremely compact footprints. I will talk about the first mode-locked Kerr frequency combs and ultrafast spectroscopic device in the mid-infrared regime\, based on silicon microresonators. Furthermore\, I will discuss a novel class of silicon-nitride-based optical parametric oscillators and its experimental realization for building a true quantum random number generator and a spatially multiplexed nanophotonic spin glasses system for coherent photonic computing. Thirdly\, I will talk about the emerging LN optoelectronic platform and show the developments of several novel EO devices and circuits for optical non-reciprocity\, femtosecond pulse lasers\, frequency-shifters\, and electro-optic frequency combs. Combination of multiple nonlinearities of LN also enables ultrabroadband optical spectral generation from ultraviolet to mid-infrared. Lastly\, I will discuss the potential of nonlinear photonic platform for scaling up and accelerating classical and quantum technologies in single-photon sources and manipulation\, photonic computing\, communication networks\, and information processing.

SUMMARY:CIS & ESE Seminar: "Wireless Systems that See the Invisible with Machine Learning: Through-Wall Vision\, Emotion Recognition\, and Health Monitoring"
DESCRIPTION:Today\, there is a huge interest in sensing technologies that can sense people and monitor their health. Yet\, existing solutions require people to wear different sensors and devices on their bodies. In contrast\, my research uses wireless signals to sense people without any physical contact. Wireless signals\, which have been traditionally used for data communication\, have great potential as a sensing modality. Specifically\, wireless signals propagate in space\, traverse walls and obstacles\, reflect off human bodies\, and get modulated by our movements\, respiration\, and even heartbeats. In this talk\, I will demonstrate how we use custom machine learning to extract semantics from wireless signals despite their complex interactions with people and the environment. In particular\, I will introduce how we develop wireless systems to detect humans through walls\, track their movements\, and recognize their actions\, enabling a form of x-ray vision. I will also show how such systems can capture people’s physiological signals\, monitor sleep stages\, and recognize emotions without putting any sensors on their bodies. Finally\, I will touch on how these new sensing technologies can help address unmet needs and reduce overhead in healthcare.

SUMMARY:CIS Seminar: "Communication Complexity\, Quantum Computing and Optimization: New Connections and Insights"
DESCRIPTION:How much information flows through a system? This fundamental question is at the heart of communication complexity. Techniques from this field have turned out to be immensely powerful and fairly universal tools to understand the power of different kinds of algorithms.\n\nIn this talk\, I will describe new methods that I have developed to analyze communication which offer fresh insights into quantum computing and optimization. Using these techniques\, I will answer a question of Aaronson and Ambainis regarding the maximal advantage that quantum algorithms can have over classical algorithms in the “blackbox” model\, and another conjecture due to Rothvoss about optimal linear programs for approximately solving the matching problem.\n\nLooking forward\, I also propose new directions to explore further connections among these areas with the intention of answering key questions regarding quantum speedups and more powerful optimization approaches\, such as semidefinite programming.

SUMMARY:CBE Seminar: "Systems Biology of Glycosylation: Examples from Cancer Biology\, Inflammatory Disease and SARS-CoV-2 Infection"
DESCRIPTION:Abstract \nGlycosylation is a common and complex post-translational modification that is orchestrated in all mammalian cells. Glycan structures thus formed either absolutely control or fine-tune various biological processes. These include the half-life of biologics in circulation\, the rates of leukocyte-endothelial cell adhesion interaction during inflammation\, tumorigenesis and the kinetics of cancer metastasis. The pattern of glycans formed on individual cells during normal health and disease depends on a family of ~350 genes that are together called the “glycogenes.” The enzymes produced by these glycogenes either add saccharides\, clip-off terminal sugar units\, or participate in the metabolic synthesis of building blocks required for glycosylation reactions. My presentation will describe novel molecular tools and complementary computational strategies to advance the study of glycosylation from a systems perspective. These represent key enabling technologies that provide new insight into the progress of diverse human diseases: cancer biology\, human inflammatory disease\, and viral infection mediated by SARS-CoV-2. The emerging knowledge suggests potential diagnostic strategies and therapeutic avenues to combat these ailments.

SUMMARY:Spring 2021 GRASP SFI: “Optimizing Orthoses: Challenges in predicting human performance”
DESCRIPTION:Abstract: Innovations in hardware and control have created a new class of orthoses or exoskeletons to augment and assist human movement. These designs enable forces and torques to be applied to nearly any segment of the body. However\, predicting how an individual will adapt their movement in response to external assistance remains incredibly challenging. These predictions are challenging for unimpaired individuals\, let alone for individuals after neurologic injury\, such as in cerebral palsy or stroke. Even for a “simple” case such as single degree-of-freedom ankle foot orthoses\, we often fail to predict how a given device will alter or improve an individual’s movement. In this seminar\, we will discuss these challenges as well as new methods that may assist in optimizing orthoses after neurologic injury. In particular\, I will discuss how machine learning can help us to learn from past prescriptions\, while also using musculoskeletal modeling\, muscle synergy analysis\, and ultrasound imaging to quantify neuromuscular adaptations and inform orthotic design. \nClick here to join the Zoom meeting

SUMMARY:ODEI Spotlight: Cultivating Equity-Focused Institutional Change in University STEM Departments
DESCRIPTION:Discipline-based education research has made great strides in understanding how to foster more equitable and effective teaching in science\, technology\, engineering\, and mathematics (STEM). However\, there still has yet to be widespread adoption of reforms in university STEM departments. Our project seeks to understand how departments can implement sustainable\, large-scale changes to undergraduate education. While these changes take many forms\, they are grounded in six core principles\, including upholding a commitment to equity\, inclusion\, and justice. We facilitate Departmental Action Teams (DATs)\, teams of faculty\, students\, and staff within a single STEM department working on some issue related to undergraduate education. During this talk\, I will present an overview of the DAT model and the principles which guide our work. I will then present some empirical research discussing how to meaningfully develop student-staff-faculty partnerships while implementing departmental changes. Finally\, I will discuss the multifaceted nature of complex equity-focused changes. \nAt 3:00 pm on Thursday\, April 1\, there will be an opportunity for grad students and post docs to join a discussion with Dr Quan. The discussion will use the same zoom link as the lecture. \nFull zoom link: https://upenn.zoom.us/j/96987577706?pwd=aEZDL3pKQkNYWXRnT2V1czE3alZxUT09 \nMeeting ID: 969 8757 7706 \nPasscode: 968501 \nPlease contact us\, penn.dip@gmail.com with any questions.

SUMMARY:MSE Seminar: "Reaction-Diffusion Driven Pattern Formation in Thermosetting Polymers"
DESCRIPTION:Reaction-diffusion processes are versatile\, yet underexplored methods for manufacturing that provide unique opportunities to control the spatial properties of materials\, achieving order through broken symmetry. The mathematical formalism and derivation of equations coupling reaction and diffusion were presented in the seminal paper by Alan Turing [Phil. Trans. R. Soc. Lond. B 237\, 37\,1952]\, which describes how random fluctuations can drive the emergence of pattern and structure from initial uniformity. Inspired by reaction-diffusion systems in nature\, this talk will describe a new processing strategy predicated on the exploitation of an advancing polymerization front sustained through coupled reaction and thermal diffusion. The system uses the exothermic release of energy to provide a positive feedback to the reaction. In turn\, this stimulates further exothermic energy release and a self-propagating reaction “front” that rapidly moves through the material – a process called frontal polymerization. We recently reported the frontal ring-opening metathesis polymerization (FROMP) of dicyclopentadiene (DCPD) that exhibits the high energy density\, high reactivity\, relatively long pot life\, and low viscosity required for the synthesis of high-performance thermosetting polymers and composites [Robertson et al.\, Nature\, 557 (2018)]. This talk will describe several novel methods to control thermal transport in this system\, giving rise to symmetry breaking events that enable complex\, emergent pattern formation and control over growth\, topology\, and shape.

SUMMARY:ESE Seminar: "Engineering (Useful) Quantum Systems"
DESCRIPTION:Quantum technologies have the potential to revolutionize sensing\, communication\, and computation. To realize this potential\, it will be necessary to scale the size and complexity of engineered quantum systems by several orders of magnitude\, without sacrificing coherence or fidelity. \nTrapped ion qubits provide unparalleled coherence and are a leading platform for current small-scale quantum technology demonstrations. Optical addressing of individual ions with low crosstalk enables high-fidelity single and multi-qubit gates\, and ions trapped in the same potential naturally allow for all-to-all connectivity. However\, free-space control and routing of these optical control fields presents a scaling challenge. I will focus on technology requirements for a deployable trapped-ion quantum sensor and introduce an integrated photonics platform for parallel laser delivery which will increase stability\, reduce size\, and allow us to increase the number of sensors measured in parallel without sacrificing fidelity. \nFinally\, I will present a path towards a modular trapped-ion quantum processor with active integrated photonics for control within each module\, and high fidelity physical and optical links between modules.

SUMMARY:BE Seminar: "Deciphering the Dynamics of the Unconscious Brain Under General Anesthesia" (Emery Brown\, MIT)
DESCRIPTION:This event will be held virtually on zoom – check email or contact ksas@seas.upenn.edu. \nGeneral anesthesia is a drug induced state that is critical for safely and humanely allowing a patient to undergo surgery or an invasive diagnostic procedure. During the last 10 years the study of the neuroscience of anesthetic drugs has been an active area of research. In this lecture we show how anesthetics create altered states of arousal by creating oscillation that impede how the various parts of the brain communicate. These oscillations\, which are readily visible on the electroencephalogram (EEG)\, change systematically with anesthetic dose\, anesthetic class and patient age. We will show how the EEG oscillations can be used to monitor the brain states of patients receiving general anesthesia\, manage anesthetic delivery and learn about fundamental brain physiology.

SUMMARY:CIS Seminar: "Expanding the Reach of Fuzzing"
DESCRIPTION:Software bugs are pervasive in modern software. As software is integrated into increasingly many aspects of our lives\, these bugs have increasingly severe consequences\, both from a security (e.g. Cloudbleed\, Heartbleed\, Shellshock) and cost standpoint. Fuzzing refers to a set of techniques that automatically find bug-triggering inputs by sending many random-looking inputs to the program under test. In this talk\, I will discuss how\, by identifying core under-generalized components of modern fuzzing algorithms\, and building algorithms that generalize or tune these components\, I have expanded the application domains of fuzzing. First\, by building a general feedback-directed fuzzing algorithm\, I enabled fuzzing to consistently find performance and resource consumption errors. Second\, by developing techniques to maintain structure during mutation\, I brought fuzzing exploration to “deeper” program states. Third\, by decoupling the user-facing abstraction of random input generators from their sampling distributions\, I built faster validity fuzzing and even tackled program synthesis. Finally\, I will discuss the key research problems that must be tackled to make fuzzing readily-available and useful to all developers.

SUMMARY:MEAM Seminar: "Lubrication and Tribology Trends and Challenges in Passenger Electric Vehicles"
DESCRIPTION:It is becoming more difficult and expensive to continue developing internal combustion engine (ICE) powered vehicles to meet the increasingly tight emissions goals addressing global climate change. Over the last few years\, automobile manufacturers have been turning their attention toward electrification as the most practical and cost-effective way of providing personal transportation options that will meet future emission standards. Multiple sources are now predicting that over the next few decades\, electric vehicles (EVs) will represent the fastest growing segment of passenger vehicle production. \nThe engine lubricants used in conventional ICE-powered personal vehicles represent one of the largest segments in the global lubricant market. It has become increasingly evident that the trend toward vehicle electrification will transform this market. However\, EVs still require the use of lubricants and other fluids to function properly. It is likely that fluids specifically developed for EVs will play an even bigger part in enabling future EV technology than their earlier counterparts did during the development of ICE-powered vehicles. \nThis presentation will examine the trends in passenger EVs from the perspective of the unique lubrication\, tribology and thermal management challenges they pose. It will also provide some insights gained from examining the layout and parts of three commercial EVs. While EV drivelines are mechanically simpler than their ICE vehicle counterparts\, they expose the lubricant to a broader range of operating conditions. Also\, the range anxiety concern expressed by consumers places an even bigger focus on friction reduction compared to ICE vehicles. Thermal management of different EV components has emerged as another technical challenge. Current fluids are not truly optimized to meet the competing requirements and there is room for future development of both the cooling systems and the fluids used in them. \nWe have now seen the first round of mass-produced EVs enter the market. Each manufacturer has developed their individual platforms and it is not clear if we have yet reached the most optimized vehicle architecture. Currently there are very few standards or even test methods to characterize the various fluids used in EVs. This will no doubt change over the next few years. We can also expect to uncover some unanticipated lubrication and tribology challenges that will require innovation and practical solutions from both vehicle manufacturers and lubricant suppliers.

SUMMARY:PICS Colloquium: "Molecular Engineering of Ice Responsive Materials: Decoding Heterogeneous Ice Nucleation"
DESCRIPTION:Abstract: The presence of particles such as dust and pollen affect cloud microphysics significantly through their effect on the state of water. These particles can hinder or accelerate the liquid-to-solid transition of water\, and also affect the ice polymorph formed in the clouds. This indirectly cloud reflectivity\, cloud lifetime\, and precipitation rates. While a predominant phenomenon\, the understanding of the surface factors that affect ice nucleation is minimal. In our research\, we use molecular simulations to illuminate the pathways through which surface properties influence ice nucleation. Experiments cannot probe the length and time scales relevant to nucleation. While molecular simulations\, in principle\, can probe the length and time scales of nucleation\, in practice nucleation is challenging to sample. Nucleation is often associated with large free energy barriers and thus\, is difficult to sample in straightforward simulations. Advanced sampling techniques and other creative approaches are needed. In this talk\, I will discuss the insights we have obtained on heterogeneous ice nucleation through studies of three surfaces – silver iodide\, kaolinite and mica. I will also highlight the synergistic combination of experiments and simulations in understanding heterogeneous ice nucleation. I will introduce a recently developed method in our group facilitate computational studies of heterogeneous nucleation. I will conclude by providing a perspective on the broader implications of our studies on interfacial phenomena and surface design.

SUMMARY:ESE Thesis Defense: "Accelerated Risk Assessment and Domain Adaptation for Autonomous Vehicles"
DESCRIPTION:Autonomous vehicles (AVs) are already driving on public roads around the US; however\, their rate of deployment far outpaces quality assurance and regulatory efforts. Consequently\, even the most elementary tasks\, such as automated lanekeeping\, have not been certified for safety\, and operations are constrained to narrow domains. First\, due to the limitations of worst-case analysis techniques\, we hypothesize that new methods must be developed to quantify and bound the risk of AVs. Counterintuitively\, the better the performance of the AV under consideration\, the harder it is to accurately estimate its risk as failures become rare and difficult to sample. This thesis presents a new estimation procedure and framework which can efficiently evaluate AV risk even in the rare event regime; we demonstrate the approach’s performance on a variety of AV software stacks. Second\, given a framework for AV evaluation\, we turn to a related question: how can AV software be efficiently adapted for new or expanded operating regimes? We hypothesize that stochastic search techniques can improve the naive trial-and-error approach commonly used today. One of the most challenging aspects of this task is that proficient driving requires making tradeoffs between performance and safety. Moreover\, for novel scenarios or operational domains there may be little data which can be used to understand the behavior of other drivers. To study these challenges we create a low-cost scale platform\, simulator\, benchmarks\, and baseline solutions. Using this testbed\, we develop a new population-based self play method for creating dynamic actors and detail both offline and online procedures for adapting AV components to these conditions. Taken as a whole\, this work represents a rigorous approach to the evaluation and improvement of AV software.
