About me

I am an assistant professor at NYU Stern in the Department of Technology, Operations and Statistics. Prior to this, I was a research fellow in the Simons Institute at UC Berkeley, and I obtained my PhD in Operations Research from MIT, advised by Prof. Vivek Farias.

My research focuses on decision-making in human-AI systems. I develop methods for data-driven decision-making and human-AI collaboration, and I study the societal impact of AI systems.
