Peter S. Ungar is Distinguished Professor and Director of the Environmental Dynamics Program at the University of Arkansas.

Before arriving at Arkansas, he taught at the Johns Hopkins School of Medicine and the Duke University Medical Center.

[1][2][3][4] He has spent thousands of hours observing wild apes and other primates in the rainforests of Latin America and Southeast Asia, studied fossils from tyrannosaurids to Neandertals, documented oral health of the Hadza Hunter-Gatherers of Tanzania, and developed new techniques for using advanced surface analysis technologies to tease information about diet from tooth shape and patterns of use wear.

[5][6][7] Ungar has written or coauthored more than 230 scientific works on ecology and evolution for books and journals including Nature, Science, Proceedings of the National Academy of Sciences, and Philosophical Transactions of the Royal Society.

[8] These have focused on food choices and feeding in living primates, and the role of diet in the evolution of human ancestors and other fossil species.
