Randolph M. Nesse is Professor of Life Sciences and the Director of the Center for Evolutionary Medicine at Arizona State University. He collaborated with the evolutionary biologist George Williams on writings that established the field of evolutionary medicine. His current research is on how understanding the evolutionary origins of responses like pain, fever, anxiety, and depression can help relieve suffering. He also investigates the origins of capacities for morality. Dr. Nesse welcomes connections with all who share his mission to establish evolutionary biology as a basic science for medicine, worldwide.
