INTRODUCTION

Hey folks! I am currently a Research Scientist at Google DeepMind. I received a Ph.D. degree at CSE, UC San Diego, advised by Prof. Julian McAuley. Prior to my Ph.D. studies, I received my bachelor’s degree in CS from Fudan University, and was fortunate to work with Dr. Xiangnan He at NeXT++, NUS. My research interests are recommender systems and broader personalized AI, including ****personalized conversational systems, retrieval models, and natural language generators.

I firmly believe that recommender systems can serve as friendly companions and guides, rather than mere feeding machines that only focus on user clicks. To this end, my current research focus revolves around next-generation recommender systems, e.g., conversational recommenders, with emphasis on (1) accuracy, (2) explainability and (3) interactivity.

My Chinese name is 何占魁 (Simplified & Traditional).
