This researcher studies self-interacting dark matter (SIDM), a proposed alternative to standard dark matter models where dark matter particles can collide and exchange energy with each other. Using computer simulations of dark matter halos (the diffuse clumps of dark matter surrounding galaxies), the work focuses on how these interactions reshape the internal density structure of galaxies and dwarf galaxies over time, including a phenomenon called 'core collapse' where the center of a halo becomes extremely dense. This research connects theoretical dark matter physics to observable signatures like galaxy density profiles and gravitational lensing.

Publication output has grown notably over the last decade, rising from just a couple of papers per year in 2017-2021 to a peak of 6-7 in 2024 and 2026, indicating an accelerating and increasingly active research pace.
