I am a Ph.D. student at NUS School of Computing and a research scientist at Betterdata. I am interested in differential privacy, especially private optimization, privacy auditing and machine unlearning.

Before starting my Ph.D., I got my Bachelor’s degree in Computer Science and Engineering from the IIT Guwahati.
