Search for Dark Matter with ATLAS

The author obtained her Diploma in Physics at the University of Mainz (JGU), Germany, in 2011 upon completion of her research project on a differential cross-section measurement of Z-boson production with the ATLAS experiment. As a CERN doctoral student, funded by a Wolfgang-Gentner-Scholarship, she made essential contributions to the operation and upgrade of the ATLAS Central Trigger and conducted a search for Dark Matter in so-called mono-jet events. She obtained her PhD "with distinction" at JGU in May 2015 and was awarded prizes for an outstanding thesis both from the ATLAS collaboration and from the physics department of JGU. Since March 2015 she has been a postdoctoral researcher at Stockholm University, coordinating the ATLAS search for leptoquarks.
