New Physics Searches with the Sun

Detecting Dark Matter in Exoplanets

Galactic Center Gamma-Ray Excess

Dark Interactions in Neutron Stars

The overarching goal of my research is discover the fundamental nature of dark matter. My approach towards achieving this goal is (i) identifying new ways that astrophysical systems can be exploited to expose new particle interactions, as well as (ii) using astrophysical datasets to discover or exclude new particle physics properties.

Astrophysical systems are highly advantageous search targets, as there is an enormous number of diverse systems that can and soon will be measured in many wavelengths. After all, the Universe has been running experiments *for us* over very long timescales (collecting dark matter, exploding and colliding systems); the outcomes already exist and are waiting to be uncovered. Celestial bodies are a playground for discovering new particle interactions!
