Assistant Professor, Carl T. Bush Professor Of Theoretical Physics
I study the first three minutes of the history of the Universe (we've zeroed things down to the first three seconds). My research program lies at the interface of particle physics, astrophysics, cosmology, and string phenomenology.
In the last couple of years, I have become interested in probing aspects of the dark sector from the perspective of astroparticle physics. This includes probing axions and dark photons using highly magnetized neutron stars, light particles emanating from neutron star mergers, studying gravitational waves from exotic compact objects made of dark sector particles, and using phase transitions to understand early Universe cosmology. I have proposed ideas to search for axions at reactor neutrino and accelerator facilities, and using X-ray polarimetry. I maintain a vigorous program of studying the Higgs boson, in particular how future gravitational wave detectors can complement future high energy colliders in probing the shape of the Higgs potential. I am interested in statistical aspects of the string landscape. I am fascinated by non-standard cosmological histories. Back in the day, I used to do formal aspects of string theory.
Research description written in 2017: Some topics I have recently worked on include: the thermal history of the universe prior to Big Bang Nucleosynthesis, models of inflation and reheating in string cosmology/effective supergravity, Affleck-Dine baryogenesis, dark radiation and its relation to the thermal history of dark matter, astrophysical probes of dark matter candidates with feeble couplings to the Standard Model, and issues of moduli stabilization and decay. I maintain an active program in collider physics. My recent interests pertain to the properties of the Higgs boson, in particular the trilinear coupling. I have worked extensively in supersymmetric model-building and signatures of SUSY models at colliders.
A full list of my publications is available on INSPIRE.
