About Me

I’m currently a Senior Applied Scientist in AWS Shanghai AI Lab. I worked for AWS in Palo Alto from Feb. 2018, and moved to Shanghai since Sep. 2019. I got my Master’s degree in Computing Science from Simon Fraser University in 2016, under the supervision of Prof. Martin Ester. My research interests are mainly on computer vision and machine learning.
