Barry P. Katz
Since 1984 when I arrived at Indiana University, I have been involved
in a wide variety of health research projects. My longest term collaborations are
focused in three major areas, sexually transmitted diseases (STD), rheumatology
and dentistry. I am the director of the Biostatistics Core for the Midwest STD Research
Center and the Mid-America Adolescent STD Research Center. In rheumatology, osteoarthritis
(OA) is my primary research area including the study of pharmacologic, educational,
and surgical interventions. We are currently analyzing data of the first multicenter
trial of a disease modifying drug for OA. I am also the director of the Biostatistics
Core for a program project to study the development of new diagnostic and treatment
methods for early dental caries, with particular emphasis on new imaging techniques.
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 a 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. 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. Currently, Wanzhu Tu and I are
developing methods for modeling data collected using daily coital diaries for which
he recently received NIH funding. In addition, based on data being collected for
the caries program project, Andrew Zhou and I are working on extending methods for
assessing diagnostic tests to data with multiple levels of correlation.
