About

I am currently pursuing a Master of Science in Financial Engineering at Columbia University.
Previously, I studied at Wuhan University.
I am fascinated by the idea of using machine learning to solve practical problems.

In my free time, I enjoy working out, travelling, reading, and watching Japanese anime. I'm passionate about language learning and am currently studying French, Japanese, and Cantonese.
I also write regularly on my blog.

I am from Dalian, China, a beautiful coastal city at the southern tip of Northeast China.
