Zhixin Xie

I am currently a Postdoctoral Fellow at University of Saarland, working with Prof. Dr. Vladimir Lazić.

I received my PhD from Université Côte d'Azur in June 2021. My supervisor was Prof. Dr. Andreas Höring. Before that I obtained my Bachelor's and Master's degree from École Polytechnique.

I am interested in algebraic geometry, especially birational geometry. I study singularities, the minimal model program and its applications.
