Research Overview

My research focuses on developing machine learning methods with a strong theoretical foundation and practical performance to address real-world decision-making problems. In recent years, we have been conducting extensive research in interactive online learning, establishing theoretical frameworks and provable solutions for information retrieval and recommendation problems. Our theoretical and algorithmic contributions have been successfully applied in an array of real-world systems, including the recommendation system in KuaiShou and Instagram, and retrieval system in Google and Bing. Our research has created several novel techniques, including online learning to rank on top of deep neural networks, and user latent intent understanding and modeling based on latent variable probabilistic models. These methods have found successful applications in critical areas such as large-scale information retrieval and recommendation systems, online education, healthcare, information integration in IoT systems, thereby creating substantial societal value.

To date, our research has generated over 140 publications, with a primary focus on top-tier conferences in the field, such as NeurIPS, ICML, ICLR, KDD, and SIGIR. Our research has been recognized with numerous awards, including the Best Paper Award at SIGIR 2019, as well as nominations for the Best Paper Award at WWW 2021 and BuildSys 2018. We have received support from the United States National Science Foundation, including the CAREER award, the United States Department of Energy, and multiple collaborations with leading industry companies, such as Google, Meta and ByteDance.

Furthermore, several of our doctoral graduate students have become tenure-track assistant professors at renowned research universities in the United States. Two of them are affiliated with the College of Information Sciences and Technology at Pennsylvania State University, and one is in the Department of Electrical Engineering and Computer Science at Oregon State University. One of our postdoctoral researchers has also moved on to become a tenure-track assistant professor at the Indian Institute of Technology's Department of Computer Science.
