I am an Assistant Professor in the School of Information Technology at York University. I earned my Ph.D in Computing Science from Simon Fraser University (2021.01 - 2024.08) under the supervision of Prof. Jian Pei. My research centers on data science, with a particular focus on data valuation in data markets and machine learning.

Research Areas: Data Science, Data Valuation, Data Market, Machine Learning

Prospective Students

I am recruiting multiple Ph.D. students with strong backgrounds in data science, databases, data engineering, or machine learning. I am particularly interested in students passionate about:

• Data markets and their applications
• Data valuation in machine learning
• Interpretation of data valuation methods

Interested applicants should email me their CV, transcripts, and a brief self-introduction with [Prospective Ph.D. Student] in the subject line. Women and individuals from underrepresented groups are especially encouraged to apply.

If you are a York University undergraduate, M.S., or admitted Ph.D. student interested in working with me, feel free to email or visit my office for a chat.
