I am a third-year PhD student at the Computer Science Department of Carnegie Mellon University. My advisor is Professor Mahadev Satyanarayanan (Satya).

My research addresses challenges in systems of machine learning, by machine learning, and for machine learning. I recently focus on edge computing and computer vision in particular. Projects I work on include Elijah and Diamond.

Before joining CMU, I researched big data systems with Professor Eric Lo (now at CUHK) at the Hong Kong Polytechnic University.

I was an early contributor to Peloton, a self-driving database being developed at CMU.

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