I am Associate Chair in the Department of Mathematics at North Dakota State University in Fargo. Here is the link to the Math department homepage.


My research deals with problems at the intersection of analytic number theory, classical Fourier analysis, and approximation problems on the real line. I am particularly interested in the Beurling-Selberg extremal problem and its generalizations to weighted versions in the metric of de Branges Hilbert spaces of entire functions.

    In my spare time I enjoy reading, writing and listening to music. I am interested in soccer and play on the team of the Math department.
