Research Interests

I am a postdoc interested in number theory. In my thesis , which I wrote under supervision of Prof. Dr. Jens Franke, I have been concerned with questions related to partial numerical verifications of the Riemann hypothesis. I am currently interested in the analytic theory of L-functions.
