SUMMARY:ESE Seminar: "Ultra-Low-Power Neural Interfaces: from Monitoring to Diagnosis and Therapy"
DESCRIPTION:Implantable and wearable medical devices are increasingly being developed as alternative therapies for intractable diseases. In particular\, undertreated neurological disorders such as epilepsy\, migraine\, and Alzheimer’s disease are of major public health concern around the world\, driving the need to explore such new approaches. Despite significant advances in neural interface systems\, the small number of recording channels in existing technology remains a barrier to their therapeutic potential. This is mainly due to the fact that simultaneous recording from a large number of electrodes imposes stringent energy and area constraints on the integrated circuits that interface with these electrodes. In this talk\, I will first discuss an efficient compressive sensing framework for multichannel cortical implants. Next\, I will present the design of our sub-microwatt per channel closed-loop seizure control device and both its in-vivo and offline performance. I will then discuss our latest work on the integration of machine learning algorithms for on-chip classification of neural data. Finally\, I will give examples of how these results may be used towards designing new devices\, to enhance the lives of millions of people suffering from disabling neurological conditions in future.

SUMMARY:CIS Seminar: "Towards Embodied Visual Intelligence"
DESCRIPTION:What would it mean for a machine to see the world? Computer vision has recently made great progress on problems such as finding categories of objects and scenes\, and poses of people in images. However\, studying such tasks in isolated disembodied contexts\, divorced from the physical source of their images\, is insufficient to build intelligent visual agents. My research focuses on remarrying vision to action\, by asking: how might vision benefit from the ability to act in the world\, and vice versa? Could embodied visual agents teach themselves through interaction and experimentation? Are there actions they might perform to improve their visual perception? How might they construct visual plans to achieve long-term action goals? In my talk\, I will set up the context for these questions\, and cover some strands of my work addressing them\, proposing approaches for self-supervised learning through proprioception\, visual prediction for decomposing complex control tasks\, and active perception. Finally\, I will discuss my long-term vision and directions that I hope to work on in the next several years

SUMMARY:CIS Seminar: "Language as a Scaffold for Grounded Intelligence:
DESCRIPTION:Abstract:\n\nNatural language can be used to construct rich\, compositional descriptions of the world\, highlighting for example entities (nouns)\, events (verbs)\, and the interactions between them (simple sentences). In this talk\, I show how compositional structure around verbs and nouns can be repurposed to build computer vision systems that scale to recognize hundreds of thousands of visual concepts in images. I introduce the task of situation recognition\, where the goal is to map an image to a language-inspired structured representation of the main activity it depicts. The problem is challenging because it requires recognition systems to identify not only what entities are present\, but also how they are participating within an event (e.g. not only that there are scissors but they are they are being used to cut). I also describe new deep learning models that better capture compositionality in situation recognition and leverage the close connection to language ‘to know what we don’t know’ and cheaply mine new training data. Although these methods work well\, I show that they have a tendency to amplify underlying societal biases in the training data (including over predicting stereotypical activities based on gender)\, and introduce a new dual decomposition method that significantly reduces this amplification without sacrificing classification accuracy. Finally\, I propose new directions for expanding what visual recognition systems can see and ways to minimize the encoding of negative social biases in our learned models.

SUMMARY:ESE Seminar: "Software\, Architecture\, and VLSI Co-Design for Efficient Task-Based Parallel Runtimes"
DESCRIPTION:Fast-paced changes across the computing stack are creating opportunities for innovation by bridging software\, architecture\, and VLSI. Cross-cutting research is challenging\, but it can expose key insights that would otherwise be hidden by abstractions. In this talk\, I will demonstrate a cross-stack approach to improve the efficiency of task-based parallel runtimes\, which are important because they underpin the parallelization of state-of-the-art graph analytics and machine learning frameworks. Shifting the focus downward\, I will discuss a cross-stack approach that addresses key circuit-level challenges in integrated voltage regulation. To finish the talk\, I will discuss my future plans to apply a cross-stack research approach to expand beyond the perceived limits of intelligence on the edge and also to decrease the challenges of complex ASIC design with hardware design techniques based on Lego-like tiling.

SUMMARY:BE Seminar: "Microfluidics and Immuno-Materials for Organs-on-a-Chip"
DESCRIPTION:This presentation will describe microfluidic technologies to conveniently produce life-like pulsatile flows along with applications to study of lung injury\, enhancement of in vitro fertilization\, and analysis of frequency-dependent cellular responses. The microfluidic technologies range from adaptation of piezo-electric actuator arrays from Braille displays to design of microfluidic circuits that can be designed to switch fluid flow on and off periodically on their own. The presentation will also describe engineered materials to mimic an aspect of the innate immune system to combat bacterial infection. More specifically\, reconstituted chromatin microwebs inspired by neutrophil extracellular traps. Using a defined composition reconstituted chromatin microweb\, we reveal impact of microweb DNA-histone ratio on bacteria capture. Additionally\, we found that E. coli\, including clinical isolates and resistant strains\, are killed more efficiently by the last-resort antibiotic\, colistin\, when bound to microwebs. Recent efforts towards incorporation of these materials into human cell systems will also be described. Time permitting\, topics on organoids\, fibrosis\, liquid-liquid phase separation\, and scaling may be incorporated.

SUMMARY:CIS Seminar: "Data Discovery: Unleashing the Value of Data"
DESCRIPTION:Organizations use only a small portion of all data they own.\nConsequently\, most of the potential value is untapped. This happens\nbecause their analysts suffer a data discovery problem: when solving a\ntask that requires data\, analysts spend more time finding the relevant\ndata than solving the task at hand. The core problem is that there is\nnot adequate infrastructure to support the many different discovery\nproblems organizations face. Hence\, finding data remains largely a\nmanual and time-consuming process. \nIn this talk I’ll present Aurum\, a system that radically changes how\nusers interact with their organizations’s data. With Aurum users can\nsolve discovery problems in minutes instead of weeks. To achieve this\,\nAurum has three novel features: 1) it makes data discovery programmable\nso users can solve many different discovery problems by writing\ndifferent programs; 2) it solves data discovery queries fast\, so users\ncan solve their problems in minutes instead of weeks; 3) it scales to\nlarge amounts of data\, so no relevant data is left behind. In addition\,\nI’ll explain how Aurum handles not only structured data such as tables\nin databases\, data lakes\, and spreadsheets\, but also unstructured data\nsuch as PDF files\, word documents\, and even conversations from Slack\nchannels. \nI’ll conclude with a vision for how to make data easier to work with and\nto program\, a key ingredient needed to exploit all data available in\norganizations and enable new applications.

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.

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.
