Professor Arttu Rajantie's research focuses on applications of quantum field theory in cosmology and particle physics. He is a member of the MoEDAL experiment at the LHC searching for magnetic monopoles produced in proton-proton and heavy-ion collisions. He lectures the Unification - the Standard Model module and is the Admissions Tutor for the Physics undergraduate programmes.

Rajantie did his PhD at the University of Helsinki, Finland, and joined Imperial College in 2005 after postdoctoral positions at the Universities of Sussex and Cambridge.
