I’m an Assistant Professor of Computer Science at NYU Shanghai. Prior to that, I received my Ph.D. in Information Science from Cornell University, where I was fortunate to be advised by Deborah Estrin. I hold a B.Eng in Computer Science from Tsinghua University.

My research interest lies in developing human-in-the-loop machine learning systems and improving long-term values of personalizations. I lead the Multimodal Adaptive Personalization Systems (MAPS) research group at NYU Shanghai. Our recent work focuses on Recommender Systems, Generative Models and their applications in Learning and Creativity.

📢 I’m looking for PhDs and undergrads to join our research group. Check our PhD program and contact me at hongyi.wen@nyu.edu if you are interested in the following topics:

  • Fairness, Robustness and Privacy in Recommender Systems (focus on ML and Optimization)
  • Personalizing Generative Language/Vision/Music Models (focus on ML and System Development)
  • Personalization in Education and Health (focus on System Development and HCI)
