Welcome to my personal website. I’m working at the
Bielefeld University , Germany, as a postdoc in the
Bielefeld Representation Theory group (BIREP) . Here you can find my CV .
Research interests
I am a geometric representation theorist, that is in the intersection between algebraic geometry and the representation theory of finite dimensional algebras. My specific interests are: Springer theory, quiver flag varieties, noncommutative resolutions of singularities, Hall algebras.
