William N Dudley

Dr. Dudley is a Professor of Public Health Education in the School of Health and Human Sciences. He received his BA in Computer Science from UNC Charlotte and PhD in Experimental Psychology from the University of Georgia. Prior to his appointment at UNCG in 2008, he served as the Director of Applied Statistics at the University Of Utah College Of Nursing. As can be seen in his cv, he has been engaged in many areas of health research including, HIV prevention, cancer symptom management and health communication. His primary research interest is the study of individual differences in trajectories of change over time, correlates of change, the discovery of typologies of change, and health outcomes related to the process of change. Of particular interest to me is the study of individual differences in trajectories of symptoms related to cancer and it treatment. Although there is considerable work in the study of change by developmental psychologist in areas such as vocabulary and substance use, there has been little work in the study of how those with chronic disease change during the course of treatment. Work in this area could lead to better predictive modeling of change in symptoms and their impact on quality of life.
