Luke Hsiao
Ph.D. Candidate
Electrical Engineering
Stanford University

I’m a final-year electrical engineering Ph.D. student at Stanford University interested in systems and networking. Earlier in my PhD, I worked with Phil Levis and Chris Ré on building hardware component knowledge bases using training data generation and multi-task learning. Now, I work with Phil Levis and Keith Winstein exploring ultra-low-latency, gaze-contingent video compression.
