Research Interests

I study the dynamical laws and matter content that determine the evolution of the universe, especially at the earliest times and highest energies. I am currently interested in how recent advances in quantum systems, quantum information, and out-of-equilbrum systems may point the way toward resolving outstanding questions in gravity and cosmology. My current projects focus mostly on open quantum systems, and on dissipative dark matter and black holes.
