Joining the lab
Prospective PhD students
Apply to the Columbia Computer Science PhD program and include me in the list of professors you're interested in. I plan to admit roughly two students in the upcoming cycle (for students starting Fall 2026).
Current Columbia PhD students
If you are a current Columbia PhD student interested in collaborating, please email me and I'll do my best to find time to meet.
Undergraduates and master's students
I hope to work with 2–4 undergrad and master's students at any one time. Fill out the interest form to get in touch. It helps, but is not required, to have taken NLP courses.
