Hansen was a Professor of Psychology at Oakland University in Rochester, Michigan. He also served as the CEO of Innovation Emporium, Inc., a company focused on knowledge management, creating sustainable industry-university partnerships, and educational environment optimization. His research in cognitive science and psychophysiology has been funded by the National Science Foundation and the National Institutes of Health. A significant portion of this work was directed toward developing a model derived from an evolutionary science perspective for integrating emotive and cognitive processes. In the past decade he has participated in creating multiple regional innovation drivers, including technology accelerators and innovation zones.
