About Me

I am a C.L.E. Moore Instructor of Mathematics at MIT (departmental postdoc)!

My official name is Jun-Ting Hsieh, but I go by the name "Tim". I completed my PhD in the Computer Science Department at Carnegie Mellon University, where I was fortunate to be advised by Pravesh K. Kothari. I am broadly interested in Theoretical Computer Science. Recently, I've been thinking about constructions of expanders and their applications in coding theory. More generally, my research interests (and prior work) include average-case algorithms, semidefinite programming and the Sum-of-Squares hierarchy, and connections between TCS and extremal combinatorics.

I will be on the academic job market in Spring 2027, for positions starting in Fall 2027.
