ESE Ph.D. Thesis Defense – “Modeling and Control of Dynamic Behavior of Spreading Processes on Networks”

Greenberg Lounge (Room 114), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

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 […]

MEAM Seminar: “The Challenges and Opportunities of Battery-Powered Flight”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Sustainable transportation and aviation are critical to address climate change and renewable energy powered battery electric vehicles represent a promising path towards this goal. I will discuss the performance metrics needed of batteries for electric land and air vehicles, and assess the energy-efficiency of electric vertical take-off and landing (eVTOL) aircraft compared to ground vehicles. […]

ESE 2022 Jack Keil Wolf Lecture – “Sustaining the Semiconductor Revolution: Challenges and Opportunities”

Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

Advancements in semiconductor integrated circuit (IC) “chip” technology over the past 60+ years have enabled exponential growth in chip functionality with exponential reduction in cost per transistor, resulting in the proliferation of information and communication devices and systems, with revolutionary impact on society; today cloud computing, big data and artificial intelligence are driving the digital […]

ESE Fall Colloquium – “On compression of, for, and with neural networks”

Zoom - Meeting ID 971 2264 9281

Data compression is enjoying a renaissance fueled by an unprecedented growth in both the amount of data being generated and our reliance on powerful computation. At its heart is an increasingly intricate interplay between compression, artificial neural networks, and (our) biological neural networks. I will survey some related research in which I have been involved, […]

ESE Fall Colloquium: “Electronics 5.0: New Materials and Devices for Edge Intelligence”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

The end of traditional transistor scaling brings unprecedented new opportunities to semiconductor devices and electronics. We are at the onset of a new technology revolution, which will focus on distributed intelligence and will be pushing the limits of sensing and computing at the edge of the cloud. This seminar will describe some of our work […]

ESE Fall Colloquium – “From Brains to Bandgaps: How Novel Materials Synthesis can provide New Semiconductor Platforms for Optoelectronics, Acoustics, Electronics and Neuromorphic Computation”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Since the first discovery of semiconductors, materials synthesis has been the driving force for new devices, new applications, and new markets. In this presentation, Professor Doolittle will provide two examples of “counterculture synthesis methods”, methods that buck literature tradition, that enable new devices, applications, and potentially vast new markets. Emphasis will be given to non-standard […]

ESE PhD Thesis Defense: “Integrated photonic-assisted electronics for phased array beamforming and delay control”

Towne 337

In recent years, electronic-photonic co-design and co-integration has emerged as a disruptive technology to augment the power of integrated circuits and deliver enhanced chip scale solutions for a variety of applications ranging from communication and sensing to imaging and computation. Coupled with the versatility of electronics, integrated photonic techniques may be employed to assist in […]

ESE PhD Thesis Defense: “Compositional Methods for Agile Quadrupedal Behaviors”

PERCH 303, Pennovation 3rd Floor 3401 Grays Ferry Avenue, Bldg 6176, Philadelphia, PA, United States

The last decade has witnessed a proliferation of legged machines with high power and force densities, as well as a commensurate development of locomotion controllers which achieve impressive empirical demonstrations. Yet, despite showing promise as a means of navigating rough terrain, these machines – and the locomotion controllers which animate them – are still restricted […]

ESE Spring Seminar – “3D Functional Mesostructures: From Neural Interfaces to Environmental Monitors”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Complex, three dimensional (3D) micro/nanostructures in biology provide sophisticated, essential functions in even the most basic forms of life. Compelling opportunities exist for analogous 3D structures in man-made devices, but existing design options are highly constrained by comparatively primitive capabilities in fabrication and growth. Recent advances in mechanical engineering and materials science provide broad access […]

ASSET Seminar: What makes learning to control easy or hard?, Nikolai Matni (University of Pennsylvania)

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

Presentation Abstract: Designing autonomous systems that are simultaneously high-performing, adaptive, and provably safe remains an open problem.  In this talk, we will argue that in order to meet this goal, new theoretical and algorithmic tools are needed that blend the stability, robustness, and safety guarantees of robust control with the flexibility, adaptability, and performance of […]
