I am a PhD student at the Computer Science Department of Carnegie Mellon University. My adivser is Professor Mahadev Satyanarayanan.

My current research interest is in distributed systems and edge computing, particularly in the presence of cloudlet.

Before joining CMU, I studied efficient big data systems with Professor Eric Lo at the Hong Kong Polytechnic University.

I am fortunate to have contributed to Peloton, a self-driving database being developed at CMU, and Acai, an open source music recommendation system supported by deep learning.
