I am a university assistant at the Faculty of Mathematics of the University of Vienna, where I work within the Numerical Harmonic Analysis Group (NuHAG).
My main interests of research include (but are not limited to) Gabor frames, lattices and special functions as well as extremal geometric problems in (harmonic) analysis. I am especially interested in the investigation of Gaussian Gabor frames and related topics such as extremal frame bounds, the study of theta functions on lattices and the heat kernel on tori.

Perler Seminar
|
My research stay at NTNU Trondheim is almost over, but before saying goodbye I will give a talk in the forum for matematiske perler (og kuriositeter) [forum for mathematical pearls (and curiosities)]. The talk, with the title The ubiquitous constant and its siblings, will be held on October 19, 2018 (12:15-13:00) and will give an overview on some of my findings during my Erwin-Schrödinger fellowship (so far).
