I’m a Ram and Vijay Shriram Data Science Postdoctoral Fellow at Stanford University, where I’m hosted by Emmanuel Candès in Statistics.

I work on developing theory and methods for reliable and responsible machine learning and data science. My work has had particular focus on modern contexts involving large-scale machine learning, societal feedback, and economic incentives.

I obtained my PhD in Electrical Engineering and Computer Sciences at UC Berkeley in 2023, where I was advised by Moritz Hardt and Michael Jordan. I spent the summer of 2020 interning at Apple AI Research, hosted by Vitaly Feldman. My PhD research was generously supported by an Apple PhD Fellowship in AI/ML. Before starting my PhD, I completed my BEng in Electrical and Computer Engineering at the University of Novi Sad in Serbia, where I was advised by Dragana Bajovic. During undergrad I spent a summer at Caltech, working with Babak Hassibi.
