Research Interests

My research focuses on topics in inflationary cosmology. 

Within that, I work on developing efficient numerical methods to solve commonly occurring differential equations, for the sake of quick Bayesian inference. I wrote oscode, a fast numerical solver for one-dimensional ordinary differential equations with highly oscillatory solutions, such as the Mukhanov-Sasaki equation or the one-dimensional Schrödinger equation.

I'm also interested in how initial conditions are set to cosmological perturbations, such as vacua in curved, expanding spacetimes.
