Key projects led: * User modeling and personalization in Search, Search advertising, and YouTube Search. Led the launches of two key p13n efforts in Google Search ads (one based on "classical" ML and one based on deep-learning based embeddings) that achieved the trifecta: better ads for users, multi-$B revenue gains for Google, and lower cost for advertisers! * Search quality measurements and modeling based on understanding user attention. * Shopping: Machine learning models for information extraction and understanding of structured / semi-structured shopping product data; the world's first conversational shopping search engine, built when BERT models roamed the planet: https://arxiv.org/abs/2109.00702 * LLMs: Earliest large-context Transformer models (ETC, BigBird), see e.g., https://arxiv.org/abs/2004.08483
