I am a Ph.D. student in Electrical Engineering and Computer Science at MIT. My advisor is Prof. Mohammad Alizadeh in Computer Science and Artificial Intelligence Laboratory.

I received my B.S. from Hong Kong University of Science and Technology, majored in Math and Computer Science, minored in Physics. I got my M.S. from MIT.
