About Me

I'm a Sr. research engineer at Google Deepmind. I obtained my Ph.D. from UC San Diego, advised by Prof. Julian McAuley. I'm interested in recommender systems, deep learning. Previously, I was fortunate to work with Prof. Wu-Jun Li and Prof. Zhi-Hua Zhou at LAMDA Group of Nanjing University. I did some work of learning binary representation (called learning to hash) of images for fast image retrieval.

I spent great summers at Google Brain (Mountain View, 2019), Pinterest Labs (San Francisco, 2018), and Adobe Research (San Jose, 2017) as a research intern.
