Haque Ishfaq

I am a final year PhD Student at Mila and McGill University, advised by Prof. Doina Precup. My current research focuses on exploration in reinforcement learning and reinforcement learning with human feedback.

I am on the job market and actively looking for Research Scientist or Postdoctoral Researcher positions in the USA/Canada!

Previously, I obtained my BS (Mathematical and Computational Science) in 2015 and MS (Statistics) in 2018 from Stanford University. There I am grateful to have my research supervised by Prof. Daniel Rubin. Previously, I also did research internships at Meta AI, Microsoft, IBM Research and Nvidia.

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

I co-organize the RLHF reading group at Mila. If you want to present your work, feel free to reach out!

In my high school days, I was heavily involved with mathematical olympiads and represented Bangladesh 3 times at the International Mathematical Olympiad (IMO).
