Jonathan Osinski
I am a mathematician working in mathematical logic, more specifically in set theory and set theoretic model theory. I am currently a PhD student and a research associate ("wissenschaftlicher Mitarbeiter")
in the Logic Group of the Department of Mathematics at the University of Hamburg. My supervisors are Yurii Khomskii and Benedikt Löwe. In my thesis project, I investigate relations of large cardinals to model theoretic properties of strong logics.
