Associate Research Professor
John Hughes

John Hughes is an Associate Research Professor of Statistics at Penn State.

Hughes received his Ph.D. in statistics from Penn State in 2011. He received his M.S. in computer science from Frostburg State University in 2002, and his B.S. in mathematics and computer science from the same in 1995.

Hughes' methodological research focuses on models for dependent data (especially high-dimensional data such as spatial and spatiotemporal data), statistical computing, and Bayesian methods. His interdisciplinary collaborations have spanned a number of fields, including environmental and occupational health, bioimaging, and the spatial epidemiology of HPV-related cancers.
