Gabriel Šaffa is a visiting Erasmus trainee for Summer 2016. He completed his bachelor and master degrees in ecology at Prešov University in Slovakia. His scientific interests are in human evolutionary ecology, with an emphasis on the role that the environment plays in shaping dietary adaptations and dietary niche construction. Currently, his work is focused on particular aspects of human life history, including the timing of menarche. During his time at the DFG Center, he will be working with isotopic data from South American populations across varying ecological settings in order to understand the patterns of weaning in hunter-gatherer and agricultural populations.
