If you’re new to college, and trying to decide how responsible to be, then here is some information.

**Research interests: **

I study representation theory of (and harmonic analysis on) p-adic groups. On the side, I have studied discrete optimization and fractal tilings of nilpotent Lie groups. More details are available on some of these. You can also see a list of my papers and preprints.

Take a look at: my academic genealogy, or my connection to Meat Loaf!

I maintained an extended letter to family and friends (not exactly a blog) when I was on leave during the 2005-06 academic year. During my leave of 2015-16, I posted some highlights. During my Fall 2022 leave, I did the following:

- worked in five countries and gave five research talks;
- met the leader of an opposition political party;
- spoke at a university graduation ceremony, but with only about 60 seconds’ notice;
- stayed COVID-free, but caught and eventually recovered from an exotic disease;
- tried out the public transportation in 7 cities;
- met, by chance, the professor of my first-ever college math course;
- learned a lot about Hecke algebras, group actions on buildings, and relative harmonic analysis. But since I hadn’t yet completed any of my projects by the end of my trip, I technically had nothing to show for it. Yet.
- Also, I spent five days purely as a tourist.
