Professor of Clinical Inquiry at Plymouth State University; and founder of the DPT program. Earned an ScD in Work Environment (Human Factors & Ergonomics) from UMass Lowell with Robert Karasek. The program at PSU is influenced by my background in ergonomics and human factors in at least two ways. First, curriculum delivery is founded on cognitive engineering and decision making theory (and its influence on learning complex tasks) and decision latitude in students to promote self regulated learners. Second, the curricular concepts of causation, adaptation and systems theory are based on my work in psychosocial ergonomics. My recent work has focused on the logical structure and use of graphical causal models to bridge research and practice as a cognitive architecture for clinical reasoning and decision making.
