About myself

I am a Zassenhaus Assistant Professor at the Ohio State University.

My research is at the intersection of number theory and ergodic theory. I often study different digital expansions of a number, such as decimal expansions, continued fraction expansions, beta-expansions, and more. One common (and very broad) question I study is: what properties are typical in non-decimal expansions and how do those properties respond to perturbations?

Beyond mathematics, my hobbies include playing piano, reading and writing speculative fiction, and experimenting with cooking.

I was born and raised in the suburbs of Portland, Oregon, and I still love the rain.

I also have a YouTube channel where I talk about a variety of math and math-adjacent topics.
