My research is in the interface between cosmology, particle physics and astrophysics with contributions in the interconnection that exists between these disciplines. I work predominantly in the area of dark matter physics and the search for the nature of the dark matter particle. I am interested in the effects of dark matter interactions to the large-scale structure of the universe, the dynamics of the expansion of the universe, the implications of cosmic variance on cosmological constraints and the disentanglement of backgrounds, as well as new statistical approaches to a wide variety of problems. I also maintain interests in high-energy astrophysics, gravitational lensing and more recently in gravitational waves and how merger events can be used to explore a variety of open questions in cosmology and galaxy formation.
