ESE Ph.D. Thesis Defense: “Analysis and Control of Neural Network Dynamical Systems”
Integrating machine learning and control systems has achieved remarkable success in controlling complex dynamical systems such as autonomous vehicles. However, the resulting controlled system often has a neural network (NN) in the loop which represents the system dynamics, control policy, or perception. The nonlinearity and large scale of NNs make it challenging to provide formal […]
MEAM Ph.D. Thesis Defense: “Enabling Ultra-Low Viscosity Lubricants Through Fundamental Understanding of ZDDPs Anti-Wear Additives and their Tribofilm Growth Mechanisms: An In-Situ Study”
Lubricants with low viscosity have the potential to improve fuel efficiency in engines due to friction reduction. However, a reduction in viscosity increases the likelihood of wear. Zinc dialkyldithiophosphate (ZDDP), the most widely used antiwear additive in engine oils, has been extensively studied over the last few decades. ZDDP forms surface-bound tribofilms at sliding contacts […]

November 15, 2022 -CIS Seminar: “Generative multitask learning mitigates target-causing confounding”
MEAM Seminar: “Cell Packings and Tissue Flows in Developing Embryos”
During embryonic development, groups of cells reorganize into functional tissues with complex form and structure. Tissue reorganization can be rapid and dramatic, often occurring through striking embryo-scale flows that are mediated by the coordinated actions of hundreds or thousands of cells. In Drosophila, cell rearrangements in the embryonic epithelium rapidly narrow and elongate the tissue, […]
ESE Fall Colloquium – “Using Information Geometry to Find Simple Models of Complex Processes”
Effective theories play a fundamental role in how we reason about the world. Although real physical processes are very complicated, useful models abstract away the irrelevant degrees of freedom to give parsimonious representations. In contrast, overly complex models can be difficult to evaluate, suffer from numerical instabilities, and may overfit data. They also obscure useful […]
ESE Ph.D. Thesis Defense – “Learning and Control of Network Phenomena”
The intersection of dynamical systems and networks are used to model a huge variety of phenomena such as the spread of disease, multi-agent systems, opinions in social networks, and more. Many properties of these network phenomena can be understood by examining the eigenvalue spectrum of a matrix representation of the underlying graph. Using this intuition, […]
CIS Seminar: “Generative multitask learning mitigates target-causing confounding”
We propose a simple and scalable approach to causal representation learning for multitask learning. Our approach requires minimal modification to existing ML systems, and improves robustness to prior probability shift. The improvement comes from mitigating unobserved confounders that cause the targets, but not the input. We refer to them as target-causing confounders. These confounders induce […]

ABSTRACT In this talk, I will first show that physics of human-like body in action already provide certain information structure which can set the natural […]
ASSET Seminar: Building Safe Autonomous Systems, Rahul Mangharam (University of Pennsylvania)
ABSTRACT: Balancing performance and safety are crucial to deploying autonomous vehicles in multi-agent environments. In particular, autonomous racing is a domain that penalizes safe but conservative policies, highlighting the need for robust, adaptive strategies. Current approaches either make simplifying assumptions about other agents or lack robust mechanisms for online adaptation. In this talk we will […]

MSE Seminar: “Advanced Microscopy Techniques for Understanding Dislocation Interactions & Damage in Complex Microstructures”
Microstructurally and compositionally complex alloys (MCCA) such as Nickel-Aluminum-Bronze (NAB) are important to Navy and maritime applications due to their high strength, toughness, and fatigue resistance, as well as excellent corrosion resistance. NAB’s are widely used in many naval applications including ship propellers, underwater fasteners, pumps, and valves. Traditional sand cast NAB alloys tend to […]
ESE Fall Colloquium – “Micro- and Nanoscale Electro-fluidics: From Basic Research to Translational Medicine”
In this talk, I will discuss my group’s work on fabricating micro- and nanosensing platforms for health monitoring. My group has developed novel electronic sensing modalities and has demonstrated their use for both in vitro with human clinical samples and in vivo in animals. In the first part of my talk, I will discuss sensor […]
ESE Ph.D. Thesis Defense – “Accelerating HLS Autotuning of Large, Highly-Parameterized Reconfigurable SoC Mappings”
High-level synthesis has accelerated the adoption of autotuners to explore design spaces. Design-space size increases exponentially in the number of design parameters, and synthesizing a single configuration for a device-scale application easily consumes hours, so existing autotuners are frequently demonstrated with small kernels and few configurations to render the problem tractable. This dissertation shows that […]

ESE Ph.D. Thesis Defense – “Robustness of Temporal Logics with Applications to Safe Autonomy”
Signal Temporal Logic (STL) is a common way to express a broad range of real-time constraints that can be imposed on control systems. Spatial robustness of STL specifications, quantifying permissible spatial perturbations, has been widely studied in the literature. However, despite the importance of various time-critical systems, temporal robustness of STL has not yet been […]
Fall 2022 GRASP on Robotics: Julie Adams, Oregon State University, “Towards Adaptive Human-Robot Teams: Workload Estimation”
This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom. ABSTRACT The ability for robots, be it a single robot, multiple robots or a robot swarm, to adapt to the humans with which they are teamed requires algorithms that allow robots to detect human performance in real time. The multi-dimensional […]
ESE Ph.D. Thesis Defense – “Modeling and Control of Dynamic Behavior of Spreading Processes on Networks”
Epidemiological spreading processes constitute the core of a large number of disparate networks. In some, faster spread is desirable, in others containing the spread is critically important. We focus on understanding the spatio-temporal spread of epidemics over contact networks with the goal of facilitating or containing the spread as the case may be. In this […]
