Fahim Tajwar

I am a PhD Student at the Machine Learning Department of Carnegie Mellon University. I am fortunate to be co-advised by Prof. Ruslan Salakhutdinov and Prof. Jeff Schneider.

Previously, I obtained my BS (with distinction, Mathemetics) in 2022 and MS (Computer Science) in 2023 from Stanford University. There I am grateful to have my research supervised by Prof. Chelsea Finn. I am also fortunate to have worked with Prof. Percy Liang, Prof. Stefano Ermon, and Prof. Stephen Luby during my time at Stanford.

Feel free to reach out to me in case you have any questions or want to chat about my work!
