Marcelo R. Sánchez-Villagra is Associate Professor of Palaeobiology at the University of Zürich. A native from Buenos Aires, he studied Biology in Caracas and obtained a PhD at Duke University and the Habilitation in Zoology from the University of Tübingen. After being Researcher at the Natural History Museum in London, he moved to Zürich and started the 'Evolutionary Morphology and Palaeobiology of Vertebrates' research group. He published Embryos in Deep Time (2012), which deals with much of his past research interest, the development and palaeobiology of vertebrate animals. He regularly leads collaborative field palaeontological work in Venezuela and he is currently working on the evo-devo of mammalian domestication.
