To define is to limit.

— Oscar Wilde · The Picture of Dorian Gray

Gravity records the presence of dark matter across the Universe, yet the particles behind that record remain unknown. I am an astroparticle physicist drawn to this distance between what we can see and what we can explain. My research follows the hidden lives of particles through the aftermath of stellar explosions, the slow accumulation of dark matter inside stars, and the dynamics of compact objects.

A supernova offers something rare in the search for dark matter: a clock. With my collaborators, I pioneered supernova-neutrino-boosted dark matter, showing how an intense neutrino burst could set elusive particles in motion and how their delayed arrival could reveal their mass. I have extended this picture to past explosions throughout the Milky Way and across cosmic history, tracing the lingering signals they may have left behind. The material surrounding an exploding star provides a complementary window. I proposed using the circumstellar medium as a calorimeter, where the decays of feebly interacting particles could deposit energy and kindle optical emission. Together, these ideas let us ask what the timing of an unseen messenger and the earliest light of a supernova might reveal about the particles behind them.

Across these cosmic laboratories, I connect particle theory with numerical modeling and multimessenger observations. A delayed arrival, a change in stellar warmth, or a fleeting excess of light can become a question precise enough for nature to answer. My aim is to turn those faint traces into measurements, letting the lives of stars tell us more about the matter we have yet to see.
