BETR Research Thrust: System Integration


Sunjin Choi received the B.S. degree in Electrical Engineering in 2020 from Seoul National University. He is currently pursuing a Ph.D. degree in Electrical Engineering at UC Berkeley, under Professor Vladimir Stojanovic. His research interests include silicon photonics, high-speed serial links, and optically-enabled computing architectures.


Wenshen Li’s current research is on the design and characterization of negative capacitance (NC) transistors toward ultra-high frequency applications. Specifically, he is applying advance radio-frequency characterization and modeling to understand high-frequency behavior of scaled NC transistors and MOS-capacitors. He is interested in exploring the fundamental limit of MOSFET scaling as well as the hafnia-zirconia material system for capacitance enhancement.
