CU Theory Student Seminar

This group is a setting for PhD students and postdocs in the theory group at Columbia to get together once a week to socialize and learn from each other. Our meetings are a mix of research and paper presentations, practice talks, and open problem sessions. We communicate primarily on the theory-phd mailing list (and also on the Columbia CS PhD Slack). Feel free to reach out to Jason, or Rashida if you'd like to give a talk, join the mailing list, or have any questions!

Spring 2023

We are meeting at 2pm every Thursday in CSB 453.
