Steven A. Frank is Donald Bren Professor and UCI Distinguished Professor in the School of Biological Sciences at the University of California, Irvine. His areas of expertise are evolutionary genetics, host-parasite interactions and social evolution.

Frank received a BS in biology from the University of Michigan, master’s degrees in statistics and zoology from the University of Florida, and a PhD in biology from the University of Michigan.

Frank develops mathematical, computational, and conceptual models to study natural selection and the evolution of organismal design. His work makes testable predictions on topics ranging from microbial life history to sociality to cancer. His study of particular topics leads to syntheses of natural selection, robustness in relation to biological design, and the commonly observed patterns that emerge from information flow and scale. Current projects: (1) Microbial life history: the fundamental forces of biological design, (2) Evolution of regulatory control, and (3) Invariance and the common patterns of nature.

Pascal Gagneux is CARTA's Executive Co-Director, a Professor of Pathology and Anthropology, and the Department Chair of Anthropology at UC San Diego. 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. Gagneux's 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.
