I am currently a Postdoctoral Researcher in the University of Vienna working with Harald Grobner. Before moving to Vienna, I was a I-SITE ULNE postdoctoral fellow in the Laboratoire Paul Painlevé at Université de Lille working with Mladen Dimitrov. Before moving to Lille, France, I obtained my PhD degree at University of Arizona, Department of Mathematics. My advisor is Romyar Sharifi. I am interested in number theory, especially Iwaswa theory, automorphic forms, HIlbert modular forms, Galois representations and their related areas. Here is my CV.
