Qualifications & Memberships
My main areas of research are cosmology and astrophysics. Recently, I have become interested in the problem of identifying the nature of dark matter. Although dark matter appears to be about six times as numerous as ordinary matter, it has not yet been detected non-gravitationally. Currently, I am investigating the use of gamma-ray observations to constrain models of dark matter self-annhilation.
