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 […]
Presented by the students of BE 370 (Medical Device Development): Come to the MedTech Panel Series to hear about these experiences and more from some of the most successful founders and CEOs in the industry! Our panelists will share their stories on how they took innovation from the bench to the boardroom and built multi-million […]
Abstract: Parallelism 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. I will present Swarm, a […]
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 […]
This professional development workshop is designed to provide Penn Engineering graduate students and postdocs with a richer understanding of what it is like to pursue a career in academia from those that have navigated the process successfully. Deputy Dean Kathleen J. Stebe (SEAS) will lead this extemporaneous panel discussions with a mix of both tenured […]
The Department of Bioengineering at the University of Pennsylvania and Dr. Rahim Rizi are pleased to announce the Doctoral Dissertation Defense of Sarmad Siddiqui. The public is welcome to attend. Location: Donner Auditorium, Basement HUP.
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 […]
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. I start with a very practical question: how can […]
Cell invasion into the surrounding matrix from nonvascularized primary tumors is the main mechanism by which cancer cells migrate to nearby blood vessels and metastasize to eventually form secondary tumors. This process is mediated by an intricate coupling between intracellular forces and extracellular forces that depend on the stiffness of the surrounding stroma and the […]
Abstract: Large datasets are being generated that can transform biology and medicine. New machine learning methods are necessary to unlock these data and open doors for scientific discoveries. In this talk, I will argue that, in order to advance science, machine learning models should not be trained in the context of one particular dataset. Instead, […]

Buckling, twisting and fracture are ubiquitous phenomena that, despite having been studied for centuries, still pose many interesting conceptual and practical challenges. In this talk, I will summarize recent theoretical and experimental work that aims to understand the role of curvature and torsion in wrinkle pattern selection, fragmentation cascades and knots. First, we will show […]
In electronics, doping silicon results in one of the most versatile functional materials ever employed. The pursuit of such functional materials in the optical domain is an area of great interest in the photonics community. I hope to convince you that whatever route photonics takes, a class of materials known as phase change materials, will […]
The skeleton of many natural and artificial structures may be abstracted as networks of nonlinearly interacting elements. Examples include rubber, gels, soft tissues, and lattice materials. Understanding the multiscale nature of deformation and failure of networked structures hold key for uncovering origins of fragility in many complex systems including biological tissues and enables designing novel […]
A major challenge in the study of dynamical systems is that of model discovery: turning data into models that are not just predictive, but provide insight into the nature of the underlying dynamical system that generated the data. This problem is made more difficult by the fact that many systems of interest exhibit parametric dependencies […]
Analog, RF and power integrated circuits are the key connectors between the physical world and the digital or cyber world. In this talk I will give my perspective on broader research trends in analog integrated circuit design research and illustrate several of these trends with results from my research group. The analog circuit design discipline […]
The Department of Bioengineering at the University of Pennsylvania and Dr. David Issadore are pleased to announce the Doctoral Dissertation Defense of Venkata "Ravi" Yelleswarapu. The public is welcome to attend.
Ionic liquids are substances that are composed entirely of ions. Negligible vapor pressures and the availability of a large number of cations and anions to tune physicochemical and biological properties for a given chemical process have been the primary drivers for research in this field over the last two decades. Majority of these investigations have […]
High-speed rotorcraft such as coaxial compound helicopters have a significant degree of control redundancy that can be exploited to minimize power requirement, noise, and vibration, in various flight conditions. This lecture focuses on a new idea – how control redundancy can be leveraged to compensate for control actuation failure. Both adaptive as well as robust […]
