# Welcome

I am currently a postdoc at Institute of Applied Mathematics, Universität Heidelberg . I have obtained my Ph.D. in mathematics at Purdue University in August 2013 under the supervision of Arshak Petrosyan. Afterwards, I was a postdoc at the Hausdorff Center for Mathematics at Bonn and CMUC at University of Coimbra . For more details, please see my CV.
