• An ROC curve is a plot of the probability of true positive as a function of the probability of false positive associated with a diagnostic test. The ROC curves are used to measure diagnostic ability - of a test as well as to compare several diagnostic tests. At present, I am developing methods for making Receiver Operating Characteristic (ROC) curves more effective for analyzing data in diagnostic clinical experiments and signal detection.

Recent Publications:

• Receiver operating characteristic studies and measurement error (with Marie Coffin), Biometrics, 1997, 53, 823-837.
• Exact powers of the Wilcoxon test and the Logrank test under random censoring (with C. H. Lin), The Journal of Statistical Planning and Inference, 1995, 48, 291-301.
• Sstratification in nonparametric ROC Studies (with Craig Beam), Biometrics, 1994, 40, 149-172.
