Roger has broad interests in particle astrophysics and cosmology. Roger and his group are currently working on studies of gravitational lensing, compact objects (black holes, neutron stars and white dwarfs) and cosmic rays, tackling difficult questions such as the unknown nature of the gamma-ray flares of the Crab Nebula. He is interested in topics which range from pure theory through phenomenological studies to analysis of observational data. Some of his groups research is strongly computational but plenty is not.
