I am a postdoc at the University of Copenhagen working in number theory and
dynamical systems on homogeneous spaces. My research interests include (but
are not restricted to) the geometry of numbers, automorphic forms, and zeros
of L-functions and zeta functions. In the period January 2014 - June 2016 my research is supported by a grant from the Danish Council for Independent Research and FP7 Marie Curie Actions-COFUND.
Previously (January 2011 - August 2013), I was a member of the Institute for Advanced Study in Princeton. I received my Ph.D. in December 2010 from Uppsala University, under the supervision of Andreas Strömbergsson.
