My research focuses on answering the biggest questions in modern cosmology. What is dark matter? What is dark energy? Is Einstein’s general relativity the complete theory of gravity?

I try to answer these questions by testing theories of dark matter, dark energy, and modified gravity using astronomical observations of stars, black holes, and gravitational waves.

Currently, my research group is working on testing theories of dark matter using black hole population statistics and helioseismology, trying to resolve the Hubble tension using early dark energy, neutron star tests of modified gravity, quantum mechanical tests of dark energy, and using machine learning to place new bounds on dark matter using stars.
