My research is in the areas of astroparticle physics and cosmology. Astroparticle physics involves research at the interface of astronomy and particle physics. It is a synergy which operates in both directions; particle physics is applied to better understand astrophysical objects as well as using the Universe as a laboratory for high-energy physics.

My group are members of the IceCube collaboration which operates the IceCube neutrino observatory at the South Pole. Our collaboration has achieved a series of break-through results discovering astrophysical neutrinos in 2013 and identifying the first source of these neutrinos in 2017.
