Welcome to my personal site! This is a place where I post some notes now and then mostly for future reference for myself, but I hope they might also be useful to others (I was going to do this on GitHub but it seemed impossible to get LaTex support for markdowns there).

I graduated from Nanjing University before coming to the U.S. for graduate study at the University of Washington in Seattle. My PhD research was in the area of silicon photonics – a technology that aims to build large-scale optical processors in a similar fashion as how we build CPUs/GPUs. While the most obvious use case is data communication, more recently silicon photonics is used for very exciting new directions such as for realizing quantum computers and for accelerating neural network computations.

During PhD, together with my labmates and academic advisors, we cofounded a startup that commercialized our research results. The startup later turned into Elenion and launched its first product in early 2017. After reaching this milestone, I decided to shift my work to a new (and at that point undetermined) direction. I explored a few different areas in which I became interested over the past a few years and eventually joined Amazon AI to work in the tremendously exciting field of machine learning (and hopefully some form of AI). I currently work in the AI Algorithms Group at Amazon Web Services, where we carry out research on various machine learning methods and algorithms as well as deploy them in Amazon products and services.

I enjoy meeting new people, learning from them and exchanging ideas. Feel free reach out for conversations on technology, startups, or careers. My contact information can be found in the left sidebar.
