Currently, I am working with Cambridge Tutoring alongside various freelance work (e.g. I have written for Veritasium and 3Blue1Brown). Before that, I worked in academia for about a decade. I was a Visiting Assistant Professor in the math department at Bates College until August 2025 (when I decided that a career in academia was no longer tenable). Before that, I had two postdoctoral appointments: the first at the Graduate Center of the City University of New York (CUNY) and the second at the Technion. I was a PhD student of Alex Kontorovich at Yale, before he migrated to Rutgers University.

Most of my research is in various areas of number theory, with some connections to geometry and logic. If you are interested, I recommend looking at either my CV or my research page (which links to my research statement).

Aside from my research interests, I am invested in mathematical outreach. I believe that it is extremely important that both undergraduate students and the general public have a better understanding of what mathematics and mathematical research is like. It seems to me that there is an enormous amount of misinformation and misapprehension toward mathematics, especially pure mathematics. I have worked in REU-type programs, given public talks, and participated in Yale’s directed reading program, all of which help address this problem in various ways. In April 2023, Springer published my book, Linear Fractional Transformations: An Illustrated Introduction in their Undergraduate Texts in Mathematics series. (For more information about this, see Books.)

I am also active on the Q and A site Quora; you can find my page here. It is in some ways similar to more specialized sites like Stack Exchange, but the user base is much broader, allowing me to reach a wider audience. At the time of writing, I have amassed over 30k followers, posting almost exclusively about mathematics; I was also listed as one of the Top Writers by Quora staff every year since 2016 until they abandoned the program in 2019. I like to think that I am doing something right. One of my proudest achievements has been writing an answer about dispelling a common misconception about polls and random samples, which ended up getting viewed by over 70k people.

A project that branched off from this was Mathematical Applications, which I started on Quora in May 2019. The motivation behind it was to create a space where vetted authors could write about how mathematics gets used in other disciplines. The readership has grown substantially, as has the number of participating writers. We have posts about everything from braid groups to modular arithmetic to category theory. Many of the things people have written about have taken me completely by surprise! I hope to see it develop further into a reference for any mathematician or layperson looking for concrete examples of how mathematics is deeply useful.
