Michael Th. Rassias

Since September 1, 2015, I am a Postdoctoral researcher (Forschungskredit Postdoc. for 2016-17) at the Institute of Mathematics of the University of Zürich and a visiting researcher at the Program in Interdisciplinary Studies of the Institute for Advanced Study, Princeton.

During the academic year 2014-2015, I was a Postdoctoral researcher at the Department of Mathematics of Princeton University and the Department of Mathematics of ETH-Zürich, conducting research at Princeton with support granted from ETH-Zürich. While at Princeton, I collaborated with Professor John F. Nash, Jr. for the preparation of the volume entitled “Open Problems in Mathematics”, Springer (Notices, AMS / IAS / BBC Radio interview).

For the period 2017-2019, I will be a member of the editorial board of the Newsletter of the European Mathematical Sociery, being in charge of the column "Solved and Unsolved Problems".


I received my Ph.D. in Mathematics from ETH-Zürich in September 2014. Supervisor: Professor Emmanuel Kowalski. Dissertation title: Analytic investigation of cotangent sums related to the Riemann zeta function.

I received my Master of Advanced Study in Mathematics (Part III of the Mathematical Tripos) from the University of Cambridge in July 2011.

I did my undergraduate studies in Greece at the School of Electrical and Computer Engineering of the National Technical University of Athens, obtaining a Diploma in March 2010.


Research Interests

My research interests lie in mathematical analysis, analytic number theory and more specifically in exponential / trigonometric sums, zeta functions, approximation theory, functional equations and analytic inequalities. I am also interested in the distribution of prime numbers and the analytic investigation of elliptic curves.

My Erdős Number is 2 via Helmut Maier.
