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 2019 NRF Fellowship for AI (accompanied with SGD 2.6 million funding), ACP 2022 Early Career Researcher Award, and was named AI's 10 to Watch by IEEE Intelligent Systems in 2020. I love teaching, and I am proud to be recipient of university-level Teaching Excellence Awards at NUS in 2022 and 2023. A longer version of bio is available here.
My primary research interest is in automated reasoning. The long term vision of my research program's 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.
Given the broad nature of the field of automated reasoning, my research group's work spans multiple traditional subfields of computer science, reflected by publication record as well as recognition in artificial intelligence (AAAI: 17×, IJCAI:13×, NeurIPS: 6×), formal methods (CAV: 7×, CP: 8×, SAT: 6×, TACAS:3×), design automation (ICCAD: 2x, DATE: 2x, DAC: 1x), and logic/databases (PODS: 4x, ICALP:1x, LPAR:4x, LICS: 2x). In short, a research group that is not bound by (traditional) borders.

Personal: I am married to fellow computer science professor Suguman Bansal. Some more info: here and hereWe have three papers accepted to AAAI-25.
The first paper takes a step towards real-time approximate model counting. Joint work with Jiong Yang and Yash Pote.
The second paper focuses on probabilistic explanations for linear models. Joint work with Bernardo Subercaseaux and Marcelo Arenas.
The third paper focuses on projected and incremental pseudo-boolean model counting. Joint work with Suwei Yang.
Our ICLP paper received Best Paper Award at ICLP-24. Joint work with Mahi Kabir. Congratulations Mahi!
Our CAV-22 paper received Distinguished Paper Award. This is second consecutive Distinguished Paper Award for our group at CAV and both of these papers are led by Jiong. Congratulations Jiong!
Our paper analyzing the performance of model counting tools in the wild is accepted to KR 2024. We showcase the limitations of competition results in predicting the performance for benchmarks arising in practice.
