I completed my PhD as part of the Marie Skłodowska-Curie European Training Network PUSHH at the Pompeu Fabra University in Barcelona. During my PhD, I analyzed ancient proteins from dental enamel of equids. My second PhD project focused on ancient dental enamel proteins from primates.  I computationally assessed how much phylogenetic signal we can expect in enamel proteins from primate fossils. 

Before moving to proteomics, I worked with sedaDNA for my Master's and Bachelor's thesis at the Potsdam University.
