I am a software engineer at Google, working on image search and photo search. Our team has been working on web scale image annotation using deep convolutional neural network, some of the recent work was described in this blog.

I received my B.Eng from Tsinghua University and Master degree from Georgia Institute of Technology. I worked with Professor Jame M.Rehg at Georgia Tech. My interests are computer vision, machine learning, and multimedia. My past research included object tracking, face/object detection and recognition, image retrieval/annotation. I also worked in Google on large scale image search, visual browsing and video object segmentation during those years, in close collaboration with Kevin Jing, Henry Rowley and Rahul Sukthankar

I love technology and enjoy using them to make people's life better. It is for this reason I co-founded VisualGraph, a cloud-based visual shopping platform in 2013. While there I developed computer vision modules for visual search engine. It was acquired by Pinterest in 2014. I believe everyone can do something dazzling as long as you have ambition, big vision, excution and persistence.

In my free time I like reading books and watching NBA games (Rockets fan for more than a decade). I also do some trading/investing mainly on US stocks. I used to be an O'Neil style investor but now I focus on both growth and value. I really enjoy doing research on public companies. Their ups and downs could provide tremendous business insights for me. My investing philosophies are (1) Individual investors can beat the market consistently because they have several advantages unavailable to institutional investors; (2) Precision is more important than recall, blind diversification is the mother of mediocrity.
