Hey, my name is Chen Luo, a Sr. Applied Scientist at Amazon Search (previously known as A9). I obtained my Ph.D. from Rice, working with Anshumali Shrivastava. Before Rice, I was a master student in Key Laboratory of Symbolic Computation and Knowledge Engineering, Jilin University. I recieved my B.S degree from the Department of Computer Science, Jilin University.

I love traveling, adventuring, having fun. I love music, love saying 'Yes!'. Above all things, I love being kind. I enjoy coding as well as reading research papers. Even though graduated from school, I still wonder if I am a scientist, an engineer or just a student. :-)


I do research for fun and my interests change more frequently than Houston weather. In short, I'm mainly focuses on solving well-known problems with new algorithms that are suitable for use on large amounts of data.
