I host office hours as part of the Learning Theory Alliance. Book a slot here.

Feel free to send me comments anonymously here. Note that, by design, I won't be able to respond -- if you need me to, it's better handled via email, or leaving some way for me to reply.

I am unable to respond to requests for internships or graduate admission applications from outside the university. If you do feel compelled to contact me in this way, I am far more likely to remember you if you demonstrate that you have genuinely engaged with my work. Instead, I recommend that you apply for graduate studies through the standard channels.

About Me

I am an Assistant Professor at the University of Waterloo's Cheriton School of Computer Science, a Faculty Member at the Vector Institute, and a Canada CIFAR AI Chair. I run The Salon. I'm interested in reliable and trustworthy statistics and machine learning, including considerations such as data privacy and robustness.

I was a Microsoft Research Fellow at the Simons Institute for the Theory of Computing for the Fall 2018 semester program on Foundations of Data Science and the Spring 2019 semester program on Data Privacy: Foundations and Applications. Before that, I completed my Ph.D. at MIT, affiliated with the Theory of Computing group in CSAIL. I was very fortunate to be advised by Costis Daskalakis.

Before MIT, I spent four wonderful years at Cornell University, graduating in May 2012 with a degree in Computer Science and Electrical and Computer Engineering. At Cornell, I was incredibly lucky to have the opportunity to work with Bobby Kleinberg.

Other Writings

We wrote a "Behind the Screens" look at STOC 2020, a document which may be useful to other virtual conference organizers. With Konstantin Makarychev, Yury Makarychev, Madhur Tulsiani, and input from Julia Chuzhoy.
Jonathan Ullman and I wrote a brief survey of differentially private statistics: A Primer on Private Statistics.
For Advanced Algorithms (6.854), I wrote a survey of matroid secretary problem algorithms as a final project.
Some bounds on the expectation of the maximum of samples from a Gaussian. I thought this was a fairly natural problem, but when I wrote it, I was unable to find anyone else who had computed the explicit lower bound here.

Other

I used to go by the name "G", though I now prefer Gautam. Also, my name is not Guatam Kamath, though it is commonly misspelled as such.
My friends Aviv Adler, Greg Bodwin, and primarily Jennifer Tang, made a small puzzle hunt for my graduation. You can check out the puzzles here: 1, 2, 3, 4, 5, 6. Warning that they can be incredibly unfair if you are not me, but oh well. Try them out!
