Since 1984 when I arrived at Indiana University, I have been involved in a wide variety of health research projects. My longest term collaboration is focused on sexually transmitted diseases (STD). I served as the director of the Biostatistics Core for a series of STD Research Centers and participated in a wide variety of epidemiologic, behavioral and randomized studies. One of the centers focused on a cohort of adolescent women that was followed for more than seven years and resulted in large number of publications describing the sexual behavior and disease risk of young women as they progress to young adulthood (e.g. Katz et. al. Sexually Transmitted Diseases, 2001).  A second area of research has been joint disease, including the study of pharmacologic, educational, and surgical interventions for osteoarthritis (OA). I directed the coordinating center for the first, and only successful, multicenter trial of a disease modifying drug for OA (Brandt et. al, Arthritis and Rheumatism, 2005). I have also had a research interest in the evaluation of new diagnostic and treatment methods for early dental caries, with particular emphasis on new imaging techniques. Two ongoing studies focus on the prediction of caries in school age children in Puerto Rico and very young children in three US sites. Currently, I am leading the statistical efforts for the multi-institutional Medical Countermeasures Against Radiological Threats (MCART) consortium which developed animal models to evaluate pharmacologic interventions to treat radiation exposure.   

My methodologic research has been based on my collaborative projects. In this way, statistical developments have direct application to real problems. This strategy has led to research in a variety of biostatistical areas. For example, based on data routinely collected as part of a sexually transmitted diseases (STD) control program, I used a deterministic model to estimate the transmission rate for chlamydial infection (Katz, Statistics in Medicine, 1992). Recently, Wanzhu Tu and I developed a stochastic model for estimating transmission using longitudinal data (Tu, et. al., Journal of the Royal Statistical Society A, 2011).  Similarly, I developed (in collaboration with former faculty member Andrew Zhou) a model of small area variation in knee replacement surgery by combining extra-Poisson regression models with empirical Bayes techniques (Zhou et. al. Statistics in Medicine, 1996). In the area of caries research, my projects related to new diagnostic methods for early caries, Ied me to propose multiple methods for combining measures of caries incidence to improve power in randomized caries trials (Katz and Huntington, Journal of Dental Research, 2004).
