About Me

I am a senior applied scientist at Amazon AGI (Artificial General Intelligence), working on foundation models for video understanding.

Before to AGI, I was a senior applied scientist at Amazon Prime Video. Prior to that, I was the senior research scientist at ByteDance/TikTok and senior applied scientist at Amazon AWS AI from 2018 to 2022, leading video related research and products. I was also one of the major contributor to open-source tools GluonCV and tools GluonMM.

I received my Ph.D. Degree (2018) at Rutgers University supervised by Prof. Ivan Marsic. I received my Bachelor’s Degree (2013) at University of Electronic Science and Technology of China.
