I work on astroparticle physics, cosmology and particle physics beyond the standard model - and thus broadly speaking on CERN-related physics (not to be confused with CERN-related physics).
My research so far has to a large degree focussed on dark matter, both in phenomenological studies and in the context of concrete models like supersymmetry or large extra dimensions (see e.g. a review on dark matter searches with gamma rays, or another review on dark matter and cosmological small-scale structure). Further interests include cosmic rays, primordial density fluctuations and cosmological structure formation, as well as global fits of new physics (within the GAMBIT project).
I am also the main current developer of DarkSUSY, a publicly available numerical packag
e to compute dark matter properties in various particle physics frameworks (i.e. not only supersymmetry, despite the name). Click on the logo to get the most recent release, or here to see the technical articles describing the current version.
For more details, see the list of articles below (the wordcloud is created from the abstracts) . A recent idea that picked up some press coverage is pandemic dark matter, proposing that the production of dark matter might have striking similarities to the spread of diseases (see also forskning.no and Abels tårn).
Recent activity
Currently our team consists besides me of Halvor Melkild (PhD cand.), Jake Gordin (PhD cand.) and Simon Nordensten (MSc cand.). Former members include Anastasia Sokolenko (now in Chicago), Francesca Calore (now at LAPTh, Annecy), Andrzej Hryczuk (now at NCBJ, Warsaw), Mitsuru Kakizaki (now in Toyama), and Martin Vollmann (now in Tübingen). I am the organizer of the semi-regular Theory seminars here at the Physics Department - so let me know if you want to contribute!
