About
The group does research on the fundamental capabilities and limitations of efficient computation.
In addition, they use computation as a lens to gain deeper insights into problems from the natural, social, and engineering sciences.
The group is highly collaborative, both within Columbia and among peer institutions. They hold a weekly Theory Lunch and a bi-weekly Student Seminar. Most graduate students have (at least) two advisors and collaborate with several professors and other students. Some of the faculty are cross-listed with the IEOR department and the Data Science Institute.
