I hold Stephen Fleming Early-Career Associate Professorship in the School of Computer Science, and an Associate Professor at the University of Toronto (on leave). Prior to moving to Toronto, I held NUS Presidential Young Professorship (at the rank of Assistant Professor) in the School of Computing at the National University of Singapore. I am a recipient of the 2019 NRF Fellowship for AI, ACP 2022 Early Career Researcher Award, and was named AI's 10 to Watch by IEEE Intelligent Systems in 2020.

My primary research interest is in automated reasoning. The long-term vision of my research program is to advance automated reasoning techniques to enable computing to deal with increasingly uncertain real-world environments. The core theme of my research program is the quest for scalability. Accordingly, our work straddles theory and practice, and draws upon ideas from randomized algorithms, statistical inference, formal methods, distribution testing, and software engineering.
