Morten S. Risager

Morten S. Risager is a Professor in the Department of Mathematical Sciences at the University of Copenhagen. His research focuses on intersections of analytic number theory, automorphic forms, and mathematical physics, particularly in quantum chaos and hyperbolic geometry. He has held positions at Aarhus University and the Institute for Advanced Study, Princeton.

• Education: Ph.D. in Mathematics (2003, University of Aarhus), M.Sc. in Mathematics (2001, University of Aarhus).

Research interests include modular symbols, Eisenstein series, lattice counting problems, and Selberg's conjecture. His recent work analyzes equidistribution in hyperbolic groups and spectral deformations.

Publications (2014–2025) cover topics like shifted convolution sums, iterated integrals of modular forms, and hyperbolic circle problems. Collaborations with Petridis and Nordentoft highlight trends in spectral theory and number theory.

Scientific awards: Steno Research Fellow (2005–2008) at Aarhus University.

Teaching areas encompass linear algebra, analysis, elliptic curves, and analytic number theory.
