Research

My main research interests are in survival analysis focusing on interval-censored data, informative censoring, and variable selection. I am also interested in longitudinal data analysis, bioinformatics, data mining, and machine learning.

While at the University of Missouri, I consulted for members of an evolutionary biology lab, and for a psychologist studying autism. At the University of Central Oklahoma, I work with groups of undergraduates undertaking consulting work as part of Project SCHOLAR.
