I’m a Ph.D. student in Computer Science at the University of Toronto, supervised by Rahul G. Krishnan. I’m interested in understanding the concepts and mechanisms that help humans in optimal decision-making, especially in healthcare. To this end, I’m working on causality and its relationship with machine learning, as well as reinforcement learning from offline observations. In particular, my research involves causal estimation and partial identification of causal effects in high-dimensional data using machine learning. I also like to explore ideas from causality, such as causal representation learning, to design interpretable machine learning methods that are robust to out-of-distribution data.

Before starting my Ph.D., I was a research intern at MPI-SWS, where I had the chance to work with Manuel Gomez Rodriguez on human-machine collaboration in reinforcement learning.

I have earned a double major B.Sc. in Computer Engineering and Mathematics from the Sharif University of Technology.
