Sebastian Matuszewski is a doctoral candidate at the Mathematics and BioSciences Group at the University of Vienna. He studied Biomathematics at the University of Greifswald. The focus of his dissertation is on the genetics of adaptation in changing environments. The goal of his PhD project is to extend existing population-genetic models of adaptation to changing environments in multi-dimensional trait spaces, and to study the influence of various aspects (e.g. pleiotropy, genetic correlations, speed and direction of environmental change) on the adaptive process.
