About Me

My name is Zachary (Zack) Porat. I am currently a PhD candidate in mathematics at Wesleyan University. My advisor is David Pollack.

My research interests lie in number theory. In particular, I study automorphic forms for congruence subgroups of SL(3, Z).

Before Wesleyan, I obtained my B.S. in Mathematics from Union College. Outside of math, I enjoy bouldering and playing trumpet.

Here is a copy of my CV, last updated in May 2024:   PDF

I am not teaching in Spring 2024.

While at Wesleyan, I have taught Elementary Statistics. I have also been a Teaching Assistant for several courses and worked in the Math Workshop.

Additionally, I have run several mentorship projects as part of Wesleyan’s Directed Reading Program.


I am currently the President of Wesleyan’s AMS Graduate Student Chapter. I am also one of the organizers of our Directed Reading Program.

Additionally, from Spring 2022 through Fall 2023, I was a co-organizer of the departmental Graduate Student Seminar.
