My research is in data privacy and trustworthy machine learning. I am interested in designing methods to quantitatively measure the privacy risks of data processing algorithms, and build scalable schemes for generalizable machine learning models that are also privacy-preserving, robust, interpretable, and fair. Our research is on analyzing the trade-offs between different pillars of trust in machine learning for practical scenarios, and on resolving such conflicts with rigorous mathematical guarantees. We are currently working on many interesting problems in this domain, including trustworthy federated learning, differential privacy for machine learning, fairness versus privacy in machine learning, privacy-aware model explanations, privacy-preserving data synthesis, and quantifying privacy risks of data analytics. Our research is supported by research awards and grants from Intel, Google, VMWare, NEC, Huawei, AI Singapore, NUS, Singapore MoE, and NRF.
I have open positions for PhD students and postdoctoral researchers. Please send me your CV and research statement.
