Research interests
I am searching for signatures of physics beyond the Standard Model of particle physics. This involves several different search paths like direct searches for Dark Matter with the CRESST experiment at Gran Sasso and indirect searches for unknown physics signatures with flavour physics. Besides this searches for new phenomena I studied aspects of the strong interaction, in particular the strong coupling constant of Quantum Chromo Dynamics (QCD).
Instrumentation and commissioning of modern high energy physics experiments is another focus of my work. Here my emphasis is on tracking, starting from the development and construction of silicon based particle detectors to calibration of tracking detectors using track based alignment algorithms.
Outreach activities
I gave several presentations about particle physics for the general public, including presentations for high school students within the High Energy Physics Masterclass program. I acted as a tour guide for various experimental setups and I participated in dedicated outreach programs approaching the public in an unusal way like the Cafe and Kosmos program.
I was in charge for the contribution from HEPHY to the exhibition "The beginning of everything. About Galaxies, Quarks and Collisions" at the Naturhistorisches Museum Wien.
During the exhibition I gave a presentation about the Standard Model of particle Physics - "Alles Quark?".
