Curriculum Vitae

Russell Gray completed his Ph.D. at the University of Auckland in 1990. He spent four years lecturing at the University of Otago, New Zealand, before returning to the School of Psychology at the University of Auckland. He is a Fellow of the Royal Society of New Zealand and has been awarded with several fellowships, as well as the inaugural Mason Durie Medal for his pioneering contributions to social science. In 2014, he became one of the two founding directors of the Max Planck Institute for the Science of Human History in Jena, Germany, where he has been heading the Department of Linguistic and Cultural Evolution. He also holds adjunct positions in the School of Psychology at the University of Auckland and the Department of Philosophy at the Australian National University. In June 2020 Russell Gray was reappointed as a director to the Max Planck Institute for Evolutionary Anthropology in Leipzig. The relocation of the Department of Linguistic and Cultural Evolution from Jena to Leipzig will be completed by the end of 2021.

Russell Gray’s research spans the areas of cultural evolution, linguistics, animal cognition, and the philosophy of biology. He helped pioneer the application of computational evolutionary methods to questions about linguistic prehistory and cultural evolution. His work has shed new insights on the 200 year-old debate on the origin of Indo-European languages, dubbed by Diamond and Bellwood as “the most intensively studied, yet still most recalcitrant problem in historical linguistics”. In collaboration with colleagues in Europe he extended this evolutionary approach to test hypotheses about the roles of culture and cognition in constraining linguistic variation. In contrast to the claims of some generative linguists, the analyses revealed striking language family specific dependencies. His core research focuses on questions about the history of languages, cultures and people in Southeast Asia and the Pacific. Together with Simon Greenhill he developed a large lexical database for the languages of this region. They analysed this data using Bayesian phylogenetic methods to test hypotheses about the sequence and timing of the peopling of the Pacific. The results revealed striking patterns of expansion pulses and pauses.

This linguistic work set the stage for his recent research applying ecological and evolutionary methods to questions about the cultural evolution of religion and the development of large-scale stratified societies both in the Pacific and around the globe. This research has found that notions of god vary with ecology, that moralising gods promote the development of social complexity, and in a darker vein, that ritual human sacrifice promotes and sustains the evolution of stratified societies. He is sometimes asked if he knows the other Russell Gray who works on New Caledonian crows. “I am Russell Crow”, he responds with a grin. With his colleagues at the University of Auckland he has found that the remarkable tool manufacturing traditions of these birds are the product of a lengthy period of socially scaffolded learning, and are underpinned by brains with large associative regions and the ability to make certain kinds of causal inference. He has published over 100 journal articles and book chapters including nine papers in Nature and Science.

In 2014, Russell Gray spoke at the Nijmegen Lectures, an annual event that showcases the best research in linguistics worldwide. He covered a range of his studies from tool use by New Caledonian Crows to quantitative work on historical linguistics to charting the evolution of political systems.
