Peter is broadly interested in theoretical physics beyond the Standard Model, including cosmology, astrophysics, general relativity, and even atomic physics. The Standard Model leaves many questions unanswered including the nature of dark matter and the origins of the fundamental fermion masses, the weak scale, and the cosmological constant. These and other clues such as the unification of the forces are a guide to building new theories beyond the Standard Model. Peter's group are interested in inventing novel experiments to uncover this new physics.

What physics lies beyond the Standard Model and how can we discover it? Professor Graham is broadly interested in theoretical physics beyond the Standard Model which often involves cosmology, astrophysics, general relativity, and even atomic physics. The Standard Model leaves many questions unanswered including the nature of dark matter and the origins of the weak scale, the cosmological constant, and the fundamental fermion masses. These clues are a guide to building new theories beyond the Standard Model. He recently proposed a new solution to the hierarchy problem which uses dynamical relaxation in the early universe instead of new physics at the weak scale. Professor Graham is also interested in inventing novel experiments to discover such new physics, frequently using techniques from astrophysics, condensed matter, and atomic physics. He is a proposer and co-PI of the Cosmic Axion Spin Precession Experiment (CASPEr) and the DM Radio experiment. CASPEr uses nuclear magnetic resonance techniques to search for axion dark matter. DM Radio uses high precision magnetometry and electromagnetic resonators to search for hidden photon and axion dark matter. He has also proposed techniques for gravitational wave detection using atom interferometry.

He was a postdoctoral research associate for one year with the particle theory group at SLAC and then took a postdoctoral position with the Stanford Institute for Theoretical Physics in the Physics Department. Graham began his appointment as Assistant Professor in the Department of Physics in September 2010.
