About me

I am currently a postdoctoral researcher at INRIA Saclay. In the summer 2019 I got my PhD degree in Mathematics at University of Zurich, under the supervision of Prof. Joachim Rosenthal.
My main research interest is Algebraic Coding Theory. I study the algebra of finite fields and its applications, with also a focus on combinatorial problems on codes. I am especially interested in rank-metric codes and their algebraic structures.
