I'm a postdoc in the Insitute of Scientific Computing at the Technische Universität Dresden. End of 2015 I have finished my PhD about “Efficient Solvers for the PhaseField Crystal Equation” supervised by Prof. Axel Voigt (TUDresden) and additionally reviewed by Prof. Steven M. Wise (The University of Tennessee).
Currently, I'm working on topics about Discrete Exterior Calculus, the PhaseField Crystal equation, active matter and the evolution of surface vector and tensor fields.
