Tim Weaver is a Professor in the Department of Anthropology, University of California, Davis, and an Associated researcher of the Human Evolution Department, Max Planck Institute for Evolutionary Anthropology. He graduated with a double major in Computer Science and Earth Sciences from Dartmouth College (1995), and he received a Ph.D. in Anthropology from Stanford University (2002). He was a postdoc in the Department of Zoology, University of Wisconsin, Madison (2003-2004), and the Human Evolution Department, Max Planck Institute for Evolutionary Anthropology (2004-2006). He joined the UC Davis Anthropology Department in 2006.

Research Focus

Professor Weaver studies human evolution, with a focus on the origins, evolution, and disappearance of Neandertals, and the related topic of the origins of humans who were anatomically and behaviorally modern. While his emphasis is on the later phases of human evolution, he has also worked on earlier periods, mostly in the context of the evolution of human bipedal walking and running and childbirth. Most of his publications address specific questions about why Neandertal, early modern human, or present-day human skeletons look the way they do. In his work, he strives to integrate approaches and datasets from population and molecular genetics with traditional studies of the fossil and archaeological records.
