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 and arithmetic geometry. I particularly enjoy the computational aspects of these subjects. Currently, I am studying 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. I also occasionally blog about my travels as a grad student.

Here is a copy of my CV, last updated in June 2025:   PDF

Teaching

I am not teaching in Spring 2025. I presented a mini-course on mathematical cryptology at SWiM@Wes 2025. I also served as a project assistant at Arithmetic Geometry at UNT.

While at Wesleyan, I have taught Calculus I and 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.

Service

I am currently one of the organizers of our Directed Reading Program.

I previously served as President (Fall 2023–Spring 2025) and Vice President (Fall 2021–Spring 2023) of Wesleyan’s AMS Graduate Student Chapter. Additionally, from Spring 2022 through Fall 2023, I was a co-organizer of the departmental Graduate Student Seminar.

Expository Notes and More

Here are some notes and code that I have put together for one reason or another. Please let me know if you find any errors.
