Katrina Yezzi-Woodley

Katrina Yezzi-Woodley

Katrina Yezzi-Woodley is a Ph.D candidate in biological anthropology at the University of Minnesota. She is interested in how meat-eating impacted human behavioral evolution. Her research focuses on how early humans were breaking bones for marrow, especially in a landscape where they competed with threatening, large-bodied carnivores for food resources. Katrina uses 3D modeling, differential geometry, and machine learning to determine how animal bones were broken at archaeological sites and how...

Risa Luther

Risa Luther

Risa Luther is a Ph.D student in (biological) anthropology at the University of Minnesota. Her research examines the process of tooth wear over the course of primate life spans in order to better understand how patterns of crown surface wear inform our understanding of function and phylogeny.    

Annie Melton

Annie Melton

Annie Melton is a Ph. D candidate in anthropological archaeology at the University of Minnesota. Broadly speaking, her research focuses on the Middle to Upper Paleolithic transition and the stone tool technological changes which took place during this period. More specifically, she seeks to understand cultural transmission processes among prehistoric populations and how archaeologists observe them via the stone tool record.
