The Association of Symbolic Logic offered generous support towards the participation of early career researchers at the Advanced Class in Set Theory (YST2019) and the European Set Theory Conference 2019. For more information see the website of the events: ESTC2019 .
Mag. Bag will join my group as a doctoral student in March 2019.
July 6 - July 10, 2020: The Erwin Schrödinger Insititute will host and fund in part a week long Workshop in Set Theory.
I 4039 International Project approved.
In July 2018, I won the Förderungspreis der Österreichischen Mathematischen Gesellschaft.
Since January 2018, I am a board member of the European Set Theory Society.
In June 2017 I was awarded the FWF START Prize which is one of the highest Austrian awards in science (FWF Project Y1012-N35 ).
