My research is in data privacy and trustworthy machine learning. I am interested in designing algorithms to quantitatively measure the privacy risks of data processing algorithms, and build scalable algorithms for generalizable machine learning models that are privacy-preserving, robust, and interpretable. We work on understanding the trade-offs between different pillars of trust in machine learning for practical scenarios, and on resolving such conflicts with mathematical rigor. I have recieved the NUS Presidential Young Professorship, for working on privacy in machine learning, the NUS Early Carrier Research Award, for working on trustworthy machine learning for high-dimensional models, the AI Singapore research award (with Yair Zick), for working on privacy-aware transparency for machine learning, and AI Singapore research award (with Li Shiuan Peh), for working on efficient and secure collaborative machine learning.
➙ I have open positions for PhD students, postdoctoral researchers, long-term (> 3 months) interns, and NUS undergraduate/master's students. Please send me your CV and research statement. Internship applicants need to fill out this form.
