My main research interest are in infinitary combinatorics, forcing, definability, as well as the study of the generalized Baire space. Prior to my current position I was a FWF-Lise-Meitner Project Leader (M1365-N13) . In June 2017 I was awarded the FWF START Prize which is the highest Austrian award for scientists under the age of 35. I am a board member of the European Set Theory Society
