About
In my research I am using weak gravitational lensing as a tool for cosmological and astrophysical investigations. My current major project responsibilities include:
- Speaker and sub-project lead of the new FWF Special Research Area (SFB) Dark UNiverse Explorations
- Euclid: National representative of Austria on the Euclid Collaboration Board. I am also leading four projects at the University of Innsbruck funded by the Austrian Research Promotion Agency (FFG) via the Austrian Space Applications Programme, which are related to the accurate measurement of weak lensing signals in data from ESA's Euclid Mission.
- South Pole Telescope: Lead of the high-redshift weak lensing follow-up campaign
- German eROSITA Consortium: Lead of the high-redshift weak lensing follow-up campaign
