My two primary interests are cosmic strings and gravitational waves. I've also done work in tunnelling processes in/statistics of potential landscapes. My cosmic string work focuses mostly on gravitational self-interactions and the production of gravitational waves by string networks, and my gravitational wave work looks at the techniques and software we use in the NANOGrav and LISA collaborations to detect gravitational waves. My landscape work bounces around (forgiving the pun), but I'm most interested in how we can apply and/or develop novel techniques for solving problems in high dimensions. You can read more about all of my research here.
My longtime collaborators and I recently finished up a major work in cosmic string gravitational self-interactions. The outcomes so far have been two preprints, one on the general results of numerical gravitational backreaction on strings, and one on the gravitational wave background produced by these backreacted strings. Stay tuned for many more developments on how backreaction affects possible cosmic string signals!

Some of my current activities are, in brief:
Analyzing the results of a large simulation of gravitational self-interaction of cosmic string loops. Outcomes will be relevant for stochastic gravitational wave detection and loop clustering in galaxies.
Looking at higher-order characteristics of gravitational wave strains.
Using MCMCs to test the ability of LISA to reconstruct cosmic string gravitational wave backgrounds.
