Due to limited platform size, most portable and wearable electronics call for a compact power management achitecture with high efficiency and high power density. The conventional buck converter requires bulky magnetics that consume a large amount of board areas. The switched capacitor (SC) converter, though promising for a fully integrated solution, is not efficient for continuous voltage...

A Learning-Based Approach to Safety in Robotic Systems

337B Cory Hall
As robotic systems become more pervasive, the need for algorithms that can ensure their safety becomes paramount. In this talk we propose a novel framework for ensuring safety in such systems. This framework is amenable to data-driven methods that learn about the system's safety through observations.

Two-Dimensional Transition Metal Dichalcogenide Materials: Wafer-Scale Synthesis, Exciton Condensation, and Catalysis for Water Splitting: Nano Seminar Series

60 Evans Hall
  • Prof. Linyou Cao, North Carolina State Univ., MSE / ECE / Physics
Two-dimensional (2D) transition metal dichalcogenide (TMDC) materials such as MoS2, WS2, MoSe2, and WSe2 present an attractive semiconductor option at the atomic level. These materials bear great promise to enable the development of novel devices in a variety of technical fields, including information technology, photonics, and clean energy. In this talk, I will present our latest progress in...

The neural circuits of the fly's olfactory memory

540 Cory Hall
  • Lou Scheffer, Howard Hughes Medical Institute
The fruit fly Drosophila will avoid odors previously associated with unpleasant experiences, and pursue odors previously associated with rewards. It has long been known that the seat of this associative learning is the Mushroom Body, a particular compartment of the fly's brain. Using a combination of genetic methods, behavioral experiments, electrophysiology, and circuit reconstruction (through...

BLISS Seminar: Phase Transitions in Generalized Linear Models

540 Cory Hall
  • Leo Miolane, INRIA
We consider generalized linear models (GLMs) where an unknown $n$-dimensional signal vector is observed through the application of a random matrix and a non-linear (possibly probabilistic) componentwise output function.

Dissertation Talk: Device Physics and Materials Properties of Two-Dimensional Semiconductors

Wang Room / 531 Cory Hall
  • Sujay Desai, UC Berkeley
Two-dimensional (2D) materials like MoS2 and WSe2 are semiconducting analogues to graphene and consist of atomically-thin layers held together by weak van der Waals (vdW) forces. By way of vdW forces, these ultrathin semiconductors can be mechanically exfoliated down to a monolayer of material (~0.7 nm thick). Monolayer 2D materials have large bandgaps, some of which exhibit direct band gap...

Capstone Showcase: Day 1

2451 Ridge Road, Shire Hall (Fung Institute for Engineering Leadership)
Each Spring, hundreds of attendees convene in Berkeley, CA for two days of social impact innovation. With 13 tracks and 100 capstone teams, see where the future of engineering is headed by uncovering the projects created in collaboration between UC Berkeley faculty, industry partners, and Master of Engineering student leaders.

Dissertation Talk: Printed organic light emitting diodes for biomedical applications

490 Cory Hall
  • Claire M. Lochner, EECS
Flexible electronics interface well with the human body, enabling wearable device implementations that were previously limited by the rigid form factors of conventional electronics. This work explores applying printed and flexible organic light emitting diodes (OLEDs) in biomedicine. A proof-of-concept solution-processed organic optoelectronic pulse oximeter is demonstrated, as well as a new OLED...
