Research

Some of my recent research is related to new estimates for the Riemann zeta-function on the line Re(s)=1 and some explicit results on a problem of Ramachandra. New preprints should come shortly.
Other recent results involve new variants of Lavrentiev's and Mergelyan's theorem with applications on Voronin Universality.
I have worked the on Hurwitz and Lerch zeta-function, and the spectral theory of automorphic forms.
I some results on the Turan Power sum method, that by a new paper of Bourgain, Dilworth, Ford, Konyagin and Kutzarova has found applications on the explicit construction of RIP-matrices (useful for compressed sensing),
My most exciting recent results are related to Universality of the multiple Hurwitz zeta-function in n complex variables. Stay tuned ...

Some of my papers can be found on the at arXiv . My PhD Thesis is available from diva-portal .

This spring I was teaching a course in Discrete mathematics at the Department of Computer and system sciences. For the next year I am working at the Department of mathematics at Stockholm University. My teaching schedule is not decided yet.
