His domain knowledge spans OpenRTB, VAST, PMP and programmatic buying, with a track record of improving video viewability and inventory quality through offline-to-real-time integrations. He started his career building cross-screen recommendation and retargeting engines and continues to favor practical, metrics-driven solutions that bridge research and production. Trained with an M.S. in Computer Science from UC Irvine and a CS BS from Shanghai Jiao Tong, he combines strong academic foundations with hands-on large-scale production experience.
