About Me

I am currently a CCAPP postdoctoral fellow in the Center for Cosmology and AstroParticle Physics at The Ohio State University. I obtained my Ph.D in Physics in June 2013 from the University of California, Santa Cruz.

My Research

My research centers on the search for indirect signals from dark matter annihilation in the universe. I am also interested in the usage of neutron stars as probes for new physics, the astrophysics of the Galactic Center region, and the evolution of massive binary stars.

research

Along with a number of colleagues, my most recent work centers on the identification and modeling of a new class of TeV sources, which we have named "TeV halos". I am currently working to understand these emission sources, and make predictions for upcoming observations by HAWC, HESS and CTA.      Read More

Latest Results

Solar Gamma-Rays

The gamma-ray flux from the Sun is brighter, goes to higher energies, and has a more complex morphology than we thought.

TeV Halos

TeV electrons accelerated by pulsars may explain the diffuse TeV excess observed by Milagro.

Dark Kinetic Heating

Dark Matter collisions with neutron stars set a minimum neutron star temperature. This may be observable with next-generation instruments.
