I am a fourth-year PhD student at the Computer Science Department of Carnegie Mellon University.
My advisor is Professor Mahadev Satyanarayanan (Satya).
I recently presented my thesis proposal (slides).

I am interested in designing and building systems of machine learning, by machine learning, and for machine learning. Currently, I focus on edge computing and computer vision. Projects I work on include Elijah (cloudlet-based edge computing) and Eureka (human-efficient discovery of training data). Eureka is part of the Intel Science and Technology Center for Visual Cloud Systems.

Before joining CMU, I researched big data systems with Professor Eric Lo (now at CUHK). I received my M.Phil. and B.S. with First Class Honors from the Hong Kong Polytechnic University.

I contributed to Peloton and submitted bug reports to MonetDB.

My colleague Junjue Wang and I maintain a reading blog on wearable cognitive assistance, video analytics systems, and computer vision.
