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 am Associate Professor at TU Wien in the Institute for Discrete Mathematics and Geometry and currently the PI of the FWF START project Y1498 and the international FWF project I6087. Moreover, I am a member of the Young Academy of the Austrian Academy of Sciences (ÖAW) and I serve as the Editor for Thesis Abstracts for the Bulletin of Symbolic Logic.

I am very glad to lead and work with this fantastic group of researchers.

In the summer there will be two inner model theory events happening in Vienna:

• June 24-28, 2024: Workshop Determinacy, Inner Models and Forcing Axioms at the Erwin Schrödinger Institute (ESI), Vienna
• July 1-5, 2024: Tutorials on Recent Advances in Inner Model Theory at TU Wien

For more information, please visit the conference website.

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. With Sargsyan: Development of a derived model representation for the Sealing model and applications towards generic absoluteness for Chang models. With Aguilera: Determination of the large cardinal strength of determinacy of projective games of length $\omega^2$. With Carroy and Medini: Analysis of the full Wadge hierarchy under determinacy and application to solve a problem in general topology.
