About Me
I am a Software Engineer at Pinterest Inc. Previously, I had my Ph.D. of Mathematics from UCLA. I was super fortunate to be co-advised by Dr. Wotao Yin and Dr. Lin Yang. My research interests are reinforcement learning (RL) and optimization. I enjoy applying mathematics theory to solve real-world problems.
I have worked on
- Efficient exploration in RL;
- Function approximation in RL;
- Offline RL.
I have a lot of hobbies, including journaling, reading, singing, dancing, traveling, and painting. I love my life and appreciate every little beauty in this world.
