Research Topics

Cosmological and astrophysical observations raise important questions for particle physics: What is the nature and origin of dark matter? What is the underlying physics which produced an asymmetry of baryonic matter over antimatter in the early universe? How can we observe the new particles and interactions introduced to answer these questions?

My research addresses these questions via model-building and phenomenology. On the model-building side, I study novel baryon number violating interactions, mechanisms which produce dark and visible matter simultaneously, and multi-component dark sectors. The phenomenological aspect of my research focuses on how new particles and interactions can be discovered, constrained, or extrapolated at experiments. In particular, I explore how rare baryon/lepton number violating processes can be observed in unexpected or extraordinary environments, cosmological signatures of dark matter, and the repercussions of new physics on cosmological observables.
