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, interpretable, and fair. 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.
NEWS ➙ We have released our ML Privacy Meter tool, which enables quantifying the privacy risks of machine learning models. Here is our short article on Aiding Regulatory Compliance by Quantifying the Privacy Risks of Machine Learning, and its talk.
➙ I have open positions for PhD students and postdoctoral researchers. Please send me your CV and research statement.
