I received my MS degree in Mechanical Engineering from the University of Colorado. I worked at the David Taylor Naval Ship Research and Development Center; at the Cooperative Institute for Research in Environmental Sciences (CIRES) for the majority of my career; and at Bolder Systems. My research and teaching has led me to the University of Wales and to the Instituto Tecnologico y de Estudios Superiores de Occidente. I’ve been excavating in Italy since 1992 and am a member of the Foundation for Calabrian Archaeology. I’m also a member of the Gu Feng Tai-Chi Club.
