I am an appliedd scientist working with Dr. Mu Li and Dr. Alex Smola in Amazon AI. Before joining Amazon, I received my PhD at UC Merced under the supervision of Shawn Newsam. My research interests mainly focus on video understanding, representation learning, semantic segmentation, and flow/depth estimation.
