Dr. Fitzmaurice has research interests in a number of areas, including methods for analysing discrete longitudinal data, models for mixed discrete and continuous outcomes, general missing data problems, methods for detecting and adjusting for overdispersion, and statistical problems in psychiatric epidemiology.

A major focus of his research is on the development of statistical methodology for analysing discrete multivariate data. In particular, he has developed likelihood-based methods for analysing multivariate binary data arising from longitudinal studies. Recently, he has begun developing methods for handling non-ignorable dropouts in longitudinal clinical trials. Dr. Fitzmaurice has also conducted research on methods for simultaneously analysing mixed discrete and continuous outcomes. The substantive foci of this latter research has been to data from developmental toxicity studies.

Dr. Fitzmaurice's research in psychiatric epidemiology has concentrated on methodological problems surrounding the use of multiple informant data in mental health surveys.

With colleagues Nan Laird and Jim Ware, Dr. Fitzmaurice published a bestselling textbook on Applied Longitudinal Analysis in 2004; work is now in progress for a 2nd edition of this book.

With colleagues Marie Davidian, Geert Verbeke and Geert Molenberghs, Dr. Fitzmaurice recently completed an edited book on Longitudinal Data Analysis.
