Since October 2011, I am a Postdoc at the Hausdorff Center for Mathematics of the University of Bonn.

I am a member of the working group of Professor Jan Schröer which is part of the Algebra and Representation Theory group.

From 2009 to 2011, I was a postdoc of la fondation des sciences mathématiques at Université Paris Diderot working with Professor Bernhard Keller.

I did my DPhil at the University of Oxford, under the supervision of Professor Karin Erdmann.

My main interest at the moment are Cluster Algebras, more specifically their categorifications which relates Cluster algebras to the representation theory of quantum groups, to quiver varieties and to triangulated categories.

I am also interested in triangulated categories, their t-structures and stability conditions.

In my thesis, I worked on Auslander-Reiten theory for algebras and derived categories, on support varieties for small quantum groups and classifications of Hopf algebras.

Research Interests

  • Cluster algebras and their categorifications
  • Representation theory of finite-dimensional algebras
  • Triangulated Categories and Differential Graded Categories
  • Quiver Varieties
My CV is available here.
