Research activities

I conduct statistical methods research in the general area of regression analysis for correlated data. I am interested in the analysis of clustered and longitudinal data, methods for count data including zero-inflated Poisson and negative binomial regression models, statistical methods for missing data, and issues pertaining to the design and analysis of cluster intervention trials. My collaborative research activities include aging, particularly observational and interventional studies concerned with the quality of long-term care in nursing homes and residential care settings for those with Alzheimer’s disease and dementia. My principal collaborative research activity is in dentistry including oral epidemiology, biological mechanisms of periodontal disease, dental caries, and craniofacial research. I apply principles of experimental design, clinical trials, epidemiology, health services research, and survey sampling methods.
