Parameswaran Kamalaruban

About Me: Since October 2020, I've been a Senior Research Associate in Safe and Ethical AI at the Turing Institute, working with Adrian Weller. Before that, I was a Postdoctoral Researcher at EPFL, working with Volkan Cevher. I completed my Ph.D. in Computer Science at the Australian National University, working with Bob Williamson. I was also attached to the Analytics program of Data61. I obtained my honors degree (B.Sc (Hons)) in Electronics and Telecommunication Engineering at the University of Moratuwa

Research Interests: (see Research Statement)
Sequential Decision Making: Experts, Bandits, and Reinforcement Learning.
Real-World Reinforcement Learning: Challenges and Opportunities.
Trustworthy Machine Learning (Robustness, Privacy, and Safety).
