About Me

I’m a research engineer at Facebook AI Research. Previously, I obtained my Master’s degree in computer vision at Carnegie Mellon University.

I work on research problems in computer vision, deep learning, reinforcement learning. I also enjoy building powerful frameworks and infrastructure for research, such as detectron2 and tensorpack.
