Since January 2015, I work as a post-doc at University of Pennsylvania, with Jim Haglund, funded by a grant from the
Knut and Alice Wallenberg foundation. Before that, (year 2014), I was working as a a post-doc,
at Universität Zurich, Schweiz with Valentin Féray.
My field of research is representation theory and combinatorics, more specifically,
polynomials given by structure constants (Kostka-coefficients, characters of the symmetric group)
and Jack generalizations of these.
In spring 2013 I defended my thesis titled _Combinatorial Methods in Complex Analysis_,
where Boris Shapiro
was my primary advisor. My research interests are mainly combinatorics,
complex analysis and algebraic geometry.
My favorite research tools are _Mathematica_, _OEIS_, _FinstStat_, _MathOverflow_, _WolframAlpha_ and _Google_.
I am also a bit interested in special polynomials,
for example real-rooted polynomials, and polynomials obtained from
Finally, I must admit that I have a soft spot for tilings, discrete dynamical systems,
machine learning, neural networks and cellular automata.

In my spare time, I tinker a bit with a flame fractal renderer written in Java.
