Om mig

Professor i Astropartikelfysik, prefekt

Undervisning

 

 

Forskning

Min grupp och försöker att hitta mörka materian i kosmos med hjälp av olika experiment: satellit- eller markbundna gammastrålningsteleskop (som Fermi Large Area Telescope och H.E.S.S.) men på senare tid i huvudsak med partikeldekterorer djupt under marken (XENON experimentet)

Förut jobbade jag med AMANDA/IceCube neutrino teleskopet (1999-2003), vid CERN inom ALICE experimentet (2004-2005) och en kortare period med satteliten PAMELA (2006/2007)

Statistisk dataanalys är något jag fokuserar på och från 2015-2018 var jag gästprofessor vid matematikinstitutionen vid Imperial College, London. Jag samarbetar gärna med statistiker.

My group, called DMAP, consists currently of one senior scientist: Jörn Mahlstedt (XENON, DARWIN lead), three post-docs: Timon Emken (LDMX/Theory), Ashley Joy (XENON), Andrea Gallo-Rosso (ALPHA) and two PhD students Cristian Antochi, Pueh Leng Tan (both XENON)

Previous members of the group (in temporal order): Jelle Aalbers (now KIPAC fellow at Stanford), Bart Pelssers (XENON, now industry),  Knut Morå (now at Columbia University), Matthew Lawson (now in Frank Wilczek's group at Fysikum), Andrea Chiappo (now industry), Boris Bauermeister (now industry),  Derek Barge (Wennergren-Fellow, now industry), Ben Farmer (now industry) Manuel Meyer (now ERC starting grant recipient at Erlangen), Miguel Sanchez Conde (now permanent University Autonoma of Madrid), Brandon Anderson (now at Head of Data Science at Stanford RegLab), Greg Martinez (now at UCLA), Hugh Dickinson (now at Open University, UK), Gerrit Spengler (now industry), Joachim Ripken (now at MPI for Solar Physics), Stephan Zimmer (now industry), Maja Llena-Garde (now at Uppsala University), Alexander Sellerholm (now industry), Tomi Ylinen (now industry).
