My research is in computer security and privacy. My current focus is on trustworthy and privacy-preserving computation (in machine learning).

  • Machine learning and data privacy
  • Adversarial machine learning
  • Interpretable machine learning
  • Privacy-preserving data synthesis
  • Distributed/collaborative learning

I have open positions for PhD students, postdoctoral researchers, long-term interns, and NUS undergraduate/master students. Please send me your CV and research statement. Internship applicants need to fill out this form.
