Michael is a 5th year graduate student working in the dissipative dark matter group on dark chemistry and dark object formation. Michael is the primary developer of the DarkKROME extension (found at https://www.bitbucket.org/mtryan83/darkkrome) to the KROME software package, which adds atomic dark matter chemistry to KROME. He is also working with David Radice on dark white dwarfs, looking into their properties and running simulations on the mergers to investigate possible GW signals. Michael has a M.S in Applied Physics from Johns Hopkins and a B.S. in Physics, Math, and Computer Science from Dickinson College.
