Over the last 10 years, Dr. Metzger has worked as a statistical analyst on several large national studies involving behavioral health issues including physical activity, child abuse and neglect, as well as injury research. He graduated with a Ph.D. in Epidemiology from the University of North Carolina – Chapel Hill in 2007. His dissertation involved the use of latent class analysis to generate physical activity groupings based on the accelerometry data from NHANES, which were then associated with distal risk factors for the metabolic syndrome. He is interested in many psychometric analytical strategies such as factor analysis and structural equation modeling, growth models, as well as the new generation of latent class analyses. In Alaska, he worked for several years as a healthcare researcher and analyst for the Southcentral Foundation, a now tribally managed Indian Health Service facility. He also has over 10 years of experience using the SAS system for most aspects of data analysis and management.
