Research
I am a dynamicist and geometer! Currently I'm working specifically in marked length spectrum rigidity and thermodynamic formalism.
When someone asks me what I do, I usually say that I'm really interested in how knowing the way things move around on an object can give us details about the shape of the object.

I'm co-organizing an AIM Research Community called Big Ideas in Dynamics with Benjamin Call. Find out more about it here!
What is...?
Dynamics
The math of what happens when things move around. Think balls on a pool table, how light travels, or what a soccer ball would do if you kicked it and watched where it went for infinite time. Dynamics, or how things move, are affected by the geometry of the space or object. I like studying how dynamics and geometry affect each other.
Marked Length Spectrum Rigidity
The marked length spectrum of a space keeps track of the lengths of the shortest closed curves (often geodesics) in a space and the homotopy class that they belong to. Marked length spectrum rigidity asks if the marked length spectrum is enough to tell you everything you need to know about the geometry of the space. Sometimes the answer is yes! This is a survey of rigidity theory by Ralf Spatzier in 2004.
Thermodynamic Formalism
Sounds like physics, right? The part of thermodynamic formalism that I'm the most interested in cares about whether or not systems have equilibrium states and if those equilibrium states are unique. There's pressure and entropy and other physics-sounding words involved, but I'm firmly on the pure math interpretation side of this.
