Amazon Inc.

Hello!

I build foundation models for Amazon Ads. I used to work on Rufus Amazon's shopping AI, and search query understanding. Before joining Amazon, I obtained my PhD degree from the Pennsylvania State University, advised by Prasenjit Mitra and Suhang Wang. Prior to this, I received my Bachelor of Engineering degree from University of Science and Technology of China.
