Donald Hedeker’s main area of expertise is in the development and use of advanced statistical methods for clustered and longitudinal data, with particular emphasis on mixed-effects models. He is the primary author of four freeware computer programs for mixed-effects analysis: MIXREG for normal-theory models, MIXOR for dichotomous and ordinal outcomes, MIXNO for nominal outcomes, and MIXPREG for counts.
In 2000, Hedeker was named a fellow of the American Statistical Association, the highest honor in his field. He was also recognized as a University Scholar by the University of Illinois that same year. He serves as an associate editor for Statistics in Medicine and the Journal of Statistical Software. He has been the principal investigator (PI), co-PI, or co-investigator on many research grants funded by the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention.
Hedeker earned a PhD in quantitative psychology and a BA in economics from the University of Chicago. He was most recently a professor of biostatistics at the University of Illinois at Chicago School of Public Health.
Hedeker joined the University of Chicago faculty in 2014.
