About Me

I am currently a researcher at MIT-IBM Watson AI Lab in Cambridge, MA, USA. I received my Ph.D. degree from the Department of Computer Science at The University of Hong Kong. I studied at the Computer Vision Lab, advised by Dr. Kenneth K.Y. Wong. I got my B.Sc. from Sun Yat-sen University in 2016.

My interests are centered around Computer Vision and Deep Learning. Current research topics include dynamic visual reasoning, multimodal learning, and image retrieval.
