About me.

I am a set theorist and my main research interests lie in the areas of inner model theory, determinacy axioms and descriptive set theory, as well as their relationships and connections to other areas of logic.

I currently hold an FWF Elise Richter Fellowship with the project Long games and determinacy when sets are universally Baire at the Institute of Discrete Mathematics and Geometry at TU Wien. The Elise Richter Programme supports highly qualified scientists to enhance their university career.

Before, I was a L'ORÉAL Austria/ÖUK/ÖAW Fellow with the project Determinacy and Large Cardinals in the logic group at the mathematics department at the University of Vienna. The L'ORÉAL Austria Fellowship is awarded in collaboration with the Austrian UNESCO Commission and in cooperation with the Austrian Academy of Sciences, with the financial support of the Federal Ministry of Education, Science and Research to support young basic researchers in the fields of medicine, the natural sciences or mathematics.

Key achievements: Proving a conjecture of Sargsyan on the consistency strength of a model of determinacy in which all sets of reals are universally Baire. Development of a new translation procedure to obtain an iterable inner model with a limit of Woodin and strong cardinals. Analysis of the hereditarily ordinal definable sets HOD in canonical inner models with finitely many Woodin cardinals (with Sargsyan). Determination of the large cardinal strength of determinacy of projective games of length $\omega^2$ (with Aguilera). Analysis of the full Wadge hierarchy under determinacy and application to solve a problem in general topology (with Carroy and Medini).
