I am interested in parasitic wasps, especially Alpine chalcid wasps of the family Pteromalidae (Chalcidoidea). Their diversity and distribution remains largely unknown - even in Switzerland, with one of the best investigated mountainous regions on earth.
My focus is on complexes of highly similar, so called cryptic species. For separating them, I use body measurements, which I explore with multivariate morphometric methods.
