I teach a few different courses. This term:

FK8006 Statitstical Methods in Physics

I am also responsible for "Forskargrenen"



My group  and I work mainly on astrophysical searches for particle dark matter, with gamma-ray telescopes on satellites (like the Fermi Large Area Telescope) and on ground (like H.E.S.S.) or in deep underground experiments (XENON). More details and links can be found on the group page - see to the right.

Statistical issues pertinent to dark matter searches are particularly close to my heart, which is why I like to collaborate with statististicans. From 2015-2018m I was a guest professor in the mathematics department since 2015. 

I have been  working with the AMANDA/IceCube neutrino telescope (1999-2003),  at CERN with the ALICE detector (2004-2005) and for a shorter period with the PAMELA (2006/07) cosmic-ray experiment.

My group, called DMAP, consists currently of one senior scientist: Alfredo Ferella; four post-docs: Derek Barge (who is Wennergren-Fellow) Boris Bauermeister, Jörn Mahlstedt, Matt Lawson; and five PhD students: Cristian Antochi, Jakob Calvén, Andrea Chiappo, Knut Morå, Bart Pelssers
