Huiman Xie Barnhart
Professor of Biostatistics and Bioinformatics

My research interests include both statistical methodology and disease-specific clinical research biostatistics. My statistical research areas include methods for assessing reliability/agreement between methods or raters, evaluating performance of new medical diagnostic tests, missing data, correlated categorical data and methods for clinical trials. My collaborative research include the following clinical areas: cardiovascular imaging, radiology imaging, cardiovascular disease, renal disease, reproductive medicine, Parkinson disease, and aging.
