What I'm doing Now

Last updated 2 January 2023

This is a now page. It is a written version of what I might say if we met in person and you asked me what I'm up to. The date at the top is important: it helps the reader determine if this is a now page or a then page.

Research Travel and News

I'm typically in either Boston or Providence.

• I will be at the Joint Math Meetings in Boston from 4 January to 7 January. I am not presenting this year.
• I'll be in New York City during the week of January 9th to January 13th. This includes attending the annual meeting of the Simons Foundation (who have supported me for the last several years).
• I'll be in Marseilles, France from late February to early March.
• I will be at AIM (in San Jose) in early March.
• I am a co-organizer of a workshop that will be held at AIM in late 2023 and I'll have more details about this soon.

Recent Travel and News

• I was at Maine-Quebec on October 15-16.
• I was at the Simons Center for Geometry and Physics roughly from 24 October to 18 November. This is at Stony Brook, NY.
• I was at the LMFDB Modular Curves Workshop, even though it is in the middle of my stay at Stony Brook.

Research

I'm currently actively working on several projects.

• I'm working to develop methods to explicitly and rigorously compute Maass forms. I'm currently implementing a rigorous form of Hejhal's algorithm for weight $0$ Maass forms in arb.
• At the same time, I'm currently writing down interrelated things about Maass forms, including implementation notes for my computational work, the theory behind rigorous evaluation, and work towards an explicit and computable trace formula for forms of nontrivial character on non-squarefree level.
• With my frequent collaborators Chan Ieong Kuan and Alex Walker, I'm investigating discrete reduction problems for the divisor function. We will release a preprint for this soon.

Teaching

I'm not currently teaching.

Fun

• I've been biking a lot. I hope to bike from Boston to Providence in spring/summer 2023. As a 2023 challenge, I'm trying to bike every street in greater Boston.
• I make my own soda. Think soda jerk. What this means is that I make syrups (typically fruity, less sweet than store bought soda) and have a CO2 tank that I use to carbonate water (typically at a bit more than typical carbonation). Our current favorites are grapefruit soda and rhubarb soda.
