Paul HeggartyPaul Heggarty is a senior scientist at the Max Planck Institute for the Science of Human History in Jena, Germany. His research focus is on language (pre)history, aiming to ensure that the perspective from linguistics is better understood outside tha field, to contribute to a more coherent, cross-disciplinary vision of the past.

Since 2008 he has convened, along with his co-editors of this book, a series of nine interdisciplinary conferences and symposia on the Andean past. Read More Read Less
