Research Interests

Research in the NeuroErgonomics Lab utilizes theories, methods, and techniques from physiology, biomechanics, neuroscience, psychology, and public health to better understand operator behavior and capabilities when interacting with simple and complex work systems.  HF/E investigations involve examining multifactorial causes and consequences of operator stress and fatigue, brain-behavior relationships with changing workforce demographics (aging, obesity), and development of HF/E tools to assess operator health and performance in hazardous work environments.
