Richard H. Madden is a research professional in the Department of Organismal Biology and Anatomy at the University of Chicago. In over 30 years of studying mammalian ecology, he has spent extensive periods conducting paleontological surveys throughout South America. His current research focuses on geographic variation in tooth wear rates in herbivores and the impact of environmental and geological processes.
