Post-Doc fellowship in the "Computational arithmetic geometry group" led by Prof. Dr. Gebhard Böckle at the Interdisciplinary Center for Scientific Computing (IWR) in Heidelberg, from October 2016.

Post-Doc fellowship at the University of Warwick for the research project LMF: L-functions and Modular Forms from October 2013 to September 2016.

I was an ALGANT Ph.D. student at Universiteit Leiden and at Université Bordeaux 1, supervisors Professor Bas Edixhoven and Professor Pierre Parent.

I have defended my Ph.D. thesis(PDF Document) on October 24th 2013.
