Research Interests:

I've written several papers on axions and on applications of machine learning to collider physics. In addition to continuing projects on these topics, I've also thought about other problems in beyond the standard model physics, including cosmological effects of neutrino interactions, dark matter models, and positivity constraints from scattering amplitudes.
