I am currently visiting Sanmi Koyejo's lab at Stanford University. Happy to chat on human-centered AI and any related topics.
I am a Ph.D. candidate in Computer Science at McGill University and Mila - Quebec AI Institute. I am delighted in working with Steve Liu and Fernando Diaz. I also collaborate with Laurent Charlin and Joelle Pineau, and have them on my supervisory committee.
My research is around human-centric AI and broadly touches personalization, evaluation, and responsibility in information access systems and recently LLMs. I am specifically interested in learning from human feedback for personalization as well as in exploring the social benefits of these technologies. Additionally, I love interdisciplinary research and am particularly interested in applying AI/ML techniques to Education and Psychology [CHI'24]. Below is a list of topics covered in some of my projects that I led or highly engaged:
- User modeling and preference elicitation [NeurIPS'24] [ICDE'24] [TOIS'23]
- Data-driven personalized recommendation [CIKM'24] [CIKM'22] [AAAI'21]
- Efficient knowledge discovery and distillation [EMNLP'24] [ICLR'24]
- Alignment to human value and social good (e.g., fairness, diversity, transparency, etc.) [NeurIPS'24] [TKDE'24] [SIGIR ICTIR'24] [SIGIR'22] [TOIS'22]
- LLMs for personalization, RLHF with personalization, ...
One of my recent engaged projects is on improving the scrutability and controllability in information access systems by using natual language as user profile for indicating preference [TEARS]. This approach builds the path to enhancing user control and autonomy in social media and information access platforms.
During my Ph.D. journey, I interned and collaborated closely with Google Research and Microsoft Research. My research is generously supported by McGill Graduate Excellence Award, Borealis AI Fellowship, and FRQNT PhD Scholarship (ranked 1st place).
