Olga Balkanova

I received my PhD degree in Mathematics in the framework of the ALGANT Joint Doctoral Program (Bordeaux, Milan, Montreal). During the fall semester 2015 I was an ICERM Postdoctoral Fellow at Brown University participating in the program on "Computational Aspects of the Langlands Program". After that I was a Visiting Researcher at the Institute for Applied Mathematics, Khabarovsk. For the 2016-2017 academic year I was a Senior Researcher at the University of Turku. Currently I am a Postdoctoral Fellow at the University of Gothenburg.

Research interests:

  • Analytic Number theory
  • L-functions
  • Spectral theory of automorphic forms
  • Maass forms of half-integral weight
  • Kloosterman sums
