Dr. Ruddell is originally from Rockford, a small town in beautiful, wet, and cold West Michigan. In addition to Arizona, he has also lived in Alaska, Massachusetts, Jordan, India, Colorado, Illinois, and Georgia. Some of his extracurricular interests include aviation, conservation, sports (including adaptive sports for the physically disabled), hiking, kayaking, mountaineering, building alternative water and energy systems, architecture, and the study of history, philosophy, and religion. He has volunteered with The Nature Conservancy, Engineering Ministries International, and a variety of nonprofit charitable organizations. He is an active member of the American Society of Civil Engineers (ASCE) and the American Geophysical Union (AGU).

Dr. Ruddell's research interests fall under the umbrella of Complex Systems, which are a special class of multi-dimensional systems that are resistant to traditional methods of modeling and analysis due to their nonlinear, multiscalar, and feedback-based properties.
