University of California, Berkeley
My primary interests involve human evolution in all its dimensions. My research emphasizes fieldwork designed to acquire new data on early hominid skeletal biology, environmental context, and behavior. I have worked on hominids spanning the Pliocene and Pleistocene, from phylogenetic and functional perspectives. In parallel with this research, but in a more behavioral realm, I have investigated bone modification in the Pleistocene of the Old World and in the Holocene Southwest United States. Research underway includes fieldwork in Ethiopia and Turkey, and laboratory studies in both countries and in Berkeley.
The Laboratory for Human Evolutionary Studies, established by F.C. Howell, is an international center for research and training. The NSF-HOMINID program project "Researching Hominid Origins Initiative" was based in this laboratory. Former graduate students have done fieldwork and/or laboratory studies in China, France, Tanzania, Malawi, Kenya, Jordan, Turkey, and Ethiopia. Current undergraduate and graduate students as well as postdocs are studying vertebrate (including hominid) paleontology and human osteology.

University of Georgia
Dorothy Fragaszy is a comparative psychologist and primatologist and Emerita Professor of Psychology at the University of Georgia. She earned her bachelor's degree at Duke University, where she fell in love with primatology when she observed mother and infant lemurs as an undergraduate research assistant. Fragaszy completed her PhD in 1978 at the University of California, Davis. She studies primates' behavior from ethological, ecological, psychological, and biomechanical perspectives. She focuses on behavioral development, learning, problem-solving, perceptual and motor skills, manual dexterity, social influences on learning, and technical traditions. For most of Fragaszy's career, she studied these topics primarily with captive capuchin monkeys and occasionally with captive chimpanzees and humans. Since 2005, she and her collaborators in the EthoCebus project (http://www.ip.usp.br/ethocebus/) have studied wild bearded capuchin monkeys in the Cerrado of Brazil. These monkeys use stone hammers to crack palm nuts and other hard, encased food items. They use stones that can weigh more than they weigh themselves, transporting them to anvils and standing bipedally to use them as hammers. Fragaszy works with collaborators from anthropology, archaeology, biology, geography and kinesiology to understand these monkeys and their unusual technical skills from as broad a perspective as possible. She has served in several elected offices of the International Primatological Society including President and Secretary General and as President of the American Society of Primatologists. She is a Fellow of the American Association for the Advancement of Science and of the Association of Psychological Science and currently serves as Editor in Chief of the Journal of Comparative Psychology, published by the American Psychological Association.
University of California San Diego
Pascal Gagneux is a Professor of Pathology and Anthropology at UC San Diego and serves as CARTA's Executive Co-Director. He is interested in the evolutionary mechanisms responsible for generating and maintaining primate molecular diversity. The Gagneux laboratory studies cell-surface molecules in closely related primates species. His focus is on glycans, the oligosaccharides attached to glycolipids and glycoproteins of the surfaces of every cell and also secreted into the extra-cellular matrix. His laboratory is exploring the roles of molecular diversity in protecting populations from pathogens as well as potential consequences for reproductive compatibility. Dr. Gagneux’s interest is in how glycan evolution is shaped by constraints from endogenous biochemistry and exogenous, pathogen-mediated natural selection, but could also have consequences for sexual selection. Dr. Gagneux has studied the behavioral ecology of wild chimpanzees in the Taï Forest, Ivory Coast, population genetics of West African chimpanzees, and differences in sialic acid biology between humans and great apes with special consideration of their differing pathogen regimes.
In 2011, while Associate Director of CARTA, Dr. Gagneux helped to establish a graduate specialization in Anthropogeny at UC San Diego. This wholly unique graduate specialization is offered through eight participating graduate programs in the social and natural sciences at UC San Diego.
Joe Henrich is currently a Harvard Professor and Chair of the Department of Human Evolutionary Biology and serves on the CARTA External Advisory Board. Before moving to Harvard, he was a professor of both Economics and Psychology at the University of British Columbia, where he held the Canada Research Chair in Culture, Cognition and Coevolution. His research deploys evolutionary theory to understand how human psychology gives rise to cultural evolution and how this has shaped our species’ genetic evolution. Using insights generated from this approach, Professor Henrich has explored a variety of topics, including economic decision-making, social norms, fairness, religion, marriage, prestige and cooperation. He’s conducted fieldwork in Peru, Chile and in the South Pacific, as well as having spearheaded several large comparative projects. In 2016, he published The Secret of Our Success: How culture is driving human evolution, domesticating our species, and making us smart. In 2018, the Social and Personality Psychology Society awarded Henrich and his team the Wegner Prize for Theoretical Innovation. Henrich is also a senior fellow in the Canadian Institute for Advanced Research (CIFAR).
University of California, Davis
Leah Krubitzer is currently a professor in the Department of Psychology and Center for Neuroscience at the University of California, Davis. She received a BS at Penn State University in Communication Disorders and a PhD in Psychology at Vanderbilt University, Nashville Tennessee. Her graduate work, under the mentorship of Dr. Jon Kaas focused on the evolution of visual cortex in primates. Her interest in the evolution of the neocortex was extended in her postdoctoral work at the University of Queensland, Australia to include a variety of mammals such as monotremes and marsupials. While in Australia she performed comparative analysis on the neocortex of a variety of different species and to date has worked on the brains of over 45 different mammals. Her current research focuses on the impact of early experience on the cortical phenotype, and she specifically examines the effects of the sensory environment on the development of connections, functional organization and behavior and seeks to understand how cultural impacts brain development. She also examines the evolution of sensory motor networks involved in manual dexterity, reaching and grasping in mammals. She received a MacArthur award for her work on evolution.

He received basic training in physiology, medicine, biology, and biochemistry at the Christian Medical College, Vellore, The University of Nebraska, and Washington University in St. Louis. He also has formal training and board certification in internal medicine, hematology, and oncology. Dr. Varki is Executive Editor of Essentials of Glycobiology (Cold Spring Harbor Press) and is recipient of a MERIT award from the NIH, and an American Cancer Society Faculty Research Award. Honorific elections include the American Academy of Arts and Sciences, the National Academy of Medicine, the American Society for Clinical Investigation, and the Association of American Physicians. He is also recipient of the three highest honors in his field, the Karl Meyer Award of the Society for Glycobiology, the International Glycoconjugate Organization Award and the Rosalind Kornfeld Award for Lifetime Achievement in Glycobiology. He is recognized for creating the first major open access research journal (J. Clin. Invest., 1996) as well as the first major open access textbook (Essentials of Glycobiology, 2009). He was honored with the Old Cottonian of Eminence Award at the 150th Anniversary of Bishop Cotton Boys School, Bangalore, India, (2015) as well as a Distinguished Faculty Medal and Oration at his medical school alma mater, CMC, Vellore. Significant past appointments include: co-head, UC San Diego Division of Hematology-Oncology; President of the Society for Glycobiology; Editor-in-chief of the Journal of Clinical Investigation; Interim director of the UC San Diego Cancer Center, President of the American Society for Clinical Investigation, and UC San Diego Associate Dean for Physician-Scientist Training. Dr. Varki's research interests are focused on a family of cell surface sugars called sialic acids, and their roles in biology, evolution and disease. Currently active projects are relevant to the roles of sialic acids in microbial infectivity, the regulation of the immune response, the progression and spread of tumors, aging, and unique aspects of human evolution. His group is particularly intrigued to find multiple interrelated differences in sialic acid biology between humans and our closest evolutionary cousins, the "great apes". These differences are a signature of the events that occurred during the last few million years of human evolution, and appear to be relevant to understanding several aspects of the current human condition, both in health and disease. Dr. Varki’s book, Denial (Twelve, Hachette Books 2013), explores a novel "Mind Over Reality Transition (MORT) theory that denying reality and personal mortality was a key step in allowing the emergence of a full theory of mind, and in the origin of our species.
