Donald Hedeker, Ph.D., is Professor of Biostatistics in the Department of Public Health Sciences of the University of Chicago. His chief expertise is in the development of statistical methods for clustered and longitudinal data, with particular emphasis on mixed-effects models. Recently, he has developed methods and software for analysis of intensive longitudinal data, which are data with many measurements over time, often collected using mobile devices and/or the internet. Such data are increasingly obtained by researchers in many research areas, for example in the areas of mobile health (mHealth) and ecological momentary assessment (EMA) studies.

In 2000, Don was named a Fellow of the American Statistical Association, and in 2015, Don received a Long-Term Excellence Award from the Health Policy Section of the American Statistical Association.
