About Me

I am currently a postdoctoral researcher at Khoury College of Computer Sciences at Northeastern University, working with Jonathan Ullman‬, ‪Hongyang Zhang, and ‪Adam Smith‬. My research is generously supported by The Khoury College Distinguished Postdoctoral Fellowship.

In August 2023, I completed my PhD at University of Toronto and Vector Institute‬ where I was fortunate to be advised by ‪Daniel M. Roy‬. I received my B.Sc. and M.Sc. degrees both in Electrical Engineering from Sharif University of Technology.

During Summer and Fall 2022‪, I was a research intern at Google Brain where I was extremely lucky to be mentored by Thomas Steinke and Abhradeep Guha Thakurta‬. I was also a research intern at Element AI‬ in Winter 2019 and Fall 2020 where I had the privilege of working with Gintare Karolina Dziugaite.

Research Interests

My research focuses broadly on various aspects of Statistical Learning Theory and Differential Privacy. For a complete list of my publications, please visit the Publications page.

I like collaborations; feel free to reach out if you find common interests.
