New Physics Searches with the Sun

Detecting Dark Matter in Exoplanets

Galactic Center Gamma-Ray Excess

Dark Interactions in Neutron Stars

Many of the fundamental processes powering our Universe can be explained to high precision by the Standard Model (SM) of Particle Physics. However, the SM cannot be a complete description of nature, as it completely fails to offer any explanation for several striking phenomena. Solutions to such problems usually require the introduction of new particles, including unknown matter or unknown force carriers, labelled as Beyond the SM (BSM) physics. In fact, as much as 95 percent of the energy-matter content of the Universe is expected to be BSM. I specialize in the ubiquitous yet mysterious matter contribution to the Universe, dark matter, and its interplay with other BSM physics.

I enjoy identifying new ways that astrophysical systems might be impacted by the presence of new particles, such as dark matter. Celestial bodies are a playground for discovering new particle interactions!
