Summary

Tooth enamel is a highly mineralized tissue and its microstructure has been intensively investigated since the 1980. Enamel formation is controlled by genetic and epigenetic processes and has been proven to be a valuable tool in questions of systematics, phylogeny, and biomechanics. The main technique is the analysis via scanning electron microscopy (SEM).

My research focusses on extinct muroid rodents (target tissue tooth enamel) as well as extinct and extant toothed xenarthral (target tissue orthodentine). In addition, I am interested in the enamel microstructure of fossil whales and extinct hooved mammals (Notoungulata) from South America.
