About me: I am a professor of Computer Science at Harvard University, and a member of the Harvard SEAS Theory of Computing group. Previously, I was a principal researcher at Microsoft Research New England, and before that I was an associate professor (with tenure) at Princeton University’s Computer Science department. I hold a Ph.D from the Weizmann Institute of Science, and was a postdoctoral fellow at the Institute for Advanced Study in Princeton. See also short biography and CV.
DUS: I am co director of undergraduate studies (DUS) of Computer Science at Harvard together with Prof. Stephen Chong. Please email firstname.lastname@example.org for any DUS related matters. For information about the Computer Science concentration at Harvard see the page csadvising.seas.harvard.edu. See also my contact information and office hours.
Current activities: Member of the editorial board of the Theory of Computing Journal (ToC) and the Electronic Colloquium of Computational Complexity. Member of the Committee for the Advancement of Theoretical Computer Science (CATCS). I am a member of the scientific board of the Simons Institute for the Theory of Computing. I am a co organizer of the Harvard Machine Learning Theory seminar. Board member and co organizer of Addis Coder. I also co-organized the New Horizons Summer School for Theoretical Computer Science. See my CV for past activities.
Former students: Sharon Goldberg (co advised with Jennifer Rexford), David Xiao (co advised with Avi Wigderson), Mohammad Mahmoody, Moritz Hardt, Zhixian Lei, Preetum Nakkiran (co-advised with Madhu Sudan)
Funding: I am currently supported by NSF award CCF 1565264, a Simons Investigator Fellowship and DARPA grant W911NF2010021. I am also grateful for support from Oracle Labs and past support by the NSF, as well as the Packard and Sloan foundations and the BSF.
Personal: I am married to Ravit Barak and father to Alma and Goren.
I am teaching CS 229br: Advanced topics in the theory of Machine Learning in Fall 2020.
Starting March 18th, I will be working remotely as part of Harvard’s (and the world’s) efforts to suppress COVID-19. See Harvard FAQ and specific information for CS undergraduates. All my office hours will be held remotely via zoom. The defaults are listed in this page but if it doesn’t work for you due to time zone differences please contact me.
I am working on a new book on “Introduction to Theoretical Computer Science”. Comments are welcome as issues/pull requests on the GitHub repository
I wrote a graduate textbook with Sanjeev Arora: Computational Complexity: A Modern Approach. I am currently writing an undergraduate textbook: Introduction to Theoretical Computer Science. I also wrote extensive notes on the sum of squares algorithm (with David Steurer). I occasionally blog on the Windows on Theory blog.
Some surveys and essays I wrote are below. See here for more of my less technical writing.
Work with what you’ve got, Nature Physics, January 21. (About experiments running the QAOA algorithm on near-term intermediate-scale noisy quantum devices (NISQ).
