#About me
Since February 2017, I am working as a postdoc with Svante Linusson at KTH (Stockholm).
Before that, (20152017) I worked as a postdoc at University of Pennsylvania,
with Jim Haglund, funded by a grant from the Knut and Alice Wallenberg foundation.
In 2014, I worked as a postdoc at Universität Zurich, Schweiz with Valentin Féray.
My field of research is representation theory and combinatorics, more specifically,
polynomials given by structure constants (Kostkacoefficients, characters of the symmetric group)
and Jack generalizations of these, as well as chromatic symmetric functions, LLT polynomials and so on.
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 realrooted polynomials and polynomials obtained from
combinatorial statistics.
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.
