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

My current research interest is in intersection between edge computing, mobile computing and machine learning. See Elijah and Diamond for some projects I am involved in.

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.
