Christina Warinner is Professor of Anthropology and Human Evolutionary Biology at Harvard University, and she leads international research groups at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany and the Leibniz Institute for Natural Products Research and Infection Biology in Jena, Germany. She is the President of the International Society for Biomolecular Archaeology (ISBA), and the recipient of the American Association for the Advancement of Science's Sussman Award for Scientific Contributions to Anthropology and the American Anthropological Association’s Exemplary Cross-Fields Award. Warinner specializes in the analysis of ancient DNA and proteins, and her research focuses on the study of ancient biomolecules to better understand past human diet, health, and the evolution of the human microbiome. She has conducted groundbreaking studies on the evolution and changing ecology of the human oral microbiome, including reconstructing the oldest microbiome to date from a 100,000-year-old Neanderthal, and she has published extensively on prehistoric migrations, the origins and spread of dairy pastoralism, and the biodiversity of the human gut microbiome. She has published two books and more than 70 peer-reviewed articles in journals, and her research has been featured in more than a hundred news articles and programs. Warinner is passionate about public education and outreach, and she co-created the Introduction to Ancient Metagenomics Summer School, which has educated more than 100 aspiring early career scientists from 18 countries. Her TED Talks have been viewed more than 2 million times, and she has been featured in documentaries produced by PBS NOVA, Netflix, and the genome sequencing company Illumina. She created the Adventures in Archaeological Science coloring book, now available in more than sixty languages, including many indigenous and underrepresented languages. She is engaged in the open science movement, and her research group has been actively involved in improving scholarly communication, data sharing, and research transparency.
