Physics of the Primordial Universe
The Big Bang theory of cosmology successfully describes the 13.7 billion years of evolutionary history of our Universe. However, it is known that the origin of the Big Bang is incomplete. We are interested in finding out what caused the Big Bang, and the physics involved in this primordial epoch. We study physics, build models and propose observables for the primordial universe using quantum field theory, general relativity and/or string theory, and test them with data from astrophysical observations.

The H3 Stellar Spectroscopic Survey
The H3 Survey is answering the question: how did the Milky Way Galaxy grow and assemble over cosmic time? To answer this question, a group of scientists at the CfA and the University of Arizona are mapping the outer limits of the Galaxy with >200,000 stars observed with the 6.5m MMT telescope in Arizona.
