Biographical Sketches: Co-Chairs

Christina Warinner
Max Planck Institute for the Science of Human History

Dr. Christina Warinner earned her Ph.D. from Harvard University in 2010, and received her postdoctoral training at the University of Zurich (2010-2012) and the University of Oklahoma (2012-2014). She became a Presidential Research Professor and Assistant Professor of Anthropology at the University of Oklahoma in 2014, and since 2016 she holds a W2 position at the Max Planck Institute for the Science of Human History in Jena, Germany. 

Dr. Warinner is pioneering the study of ancient human microbiota, and in 2014 she published the first detailed metagenomic and metaproteomic characterization of the ancient human oral microbiome. In 2015, she published a seminal study on the identification of milk proteins in ancient dental calculus and the reconstruction of prehistoric European dairying practices. In the same year, she also was part of a large team that the published the first South American hunter-gatherer gut microbiome and identified Treponema as a key missing ancestral microbe in industrialized societies. She has published two books and numerous peer-reviewed journal articles in peer-reviewed journals such as Nature GeneticsPNASCurrent Biology and Nature Communications, and she serves on the Editorial Board of Scientific Reports, a Nature Publishing Group journal. 

Her research has earned her Honorable Mention for the Omenn Prize, an annual prize for best article published on evolution, medicine and public health, and her ancient microbiome findings were named among the top 100 scientific discoveries of 2014 by Discover Magazine. Her research has been featured in more than 75 news articles, including stories in ScienceCellScientific AmericanDiscover Magazine, The New ScientistArchaeology Magazinethe LA Timesthe GuardianEl PaisWIRED UK, and CNN, among others. She has presented before the Royal Society of London (2013) and on behalf of the Leakey Foundation (2013, 2016), and in 2015 she was an invited participant at the White House Microbiome Innovation Forum sponsored by the US Office of Science and Technology Policy (OSTP). She has been featured in two documentaries produced by the genome sequencing company Illumina, and her current work on ancient Nepal appears in the award-winning children’s book, Secrets of the Sky Caves. She is a US National Academy of Sciences Kavli Fellow (2014) and a TED Fellow (2012). Her TED Talks on ancient dental calculus and the evolution of the human diet have been viewed more than 1.5 million times. 

Johannes Krause
Max Planck Institute for the Science of Human History

Johannes Krause (born 1980) is a native of Thuringia. In 2008, he received his Ph.D. in Genetics at the University of Leipzig. Subsequently, he worked at the Max Planck Institute for Evolutionary Anthropology in Leipzig, before he was appointed Professor for Archeology and Paleogenetics at the University of Tübingen, at the Institute for Archaeological Sciences.

Johannes Krause focusses on the analysis of old to very old DNA using the DNA sequencing. His research interests include pathogens from historical epidemics, as well as human evolution.  He also contributed to the deciphering of the genetic heritage of Neanderthals, and managed to prove that Neanderthals and modern humans share the same language gene ( FOXP2). In 2010, while working at the Max Planck Institute for Evolutionary Anthropology in Leipzig, he discovered the first genetic evidence of the Denisovans, a stone-age primeval Homo species from Siberia. With his work on the evolution of historical infectious diseases, he was able to demonstrate that most of today's plague pathogen originated in the Middle Ages.

Johannes Krause is a collegiate of the Heidelberg Academy of Sciences and was awarded the AAAS Newcomb Cleveland Prize.

Biographical Sketches: Speakers

Pascal Gagneux
UC San Diego

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.
