My research focuses on the development and application of psychometric methods to practical problems in industrial organizational and educational settings. I have worked with university faculty and practitioners to develop and improve tests measuring constructs, such as job performance, personality, and cognitive ability. My colleagues and I have published papers on computer adaptive testing, differential item and test functioning (measurement bias), and issues related to faking in personality assessment. Courses I have taught at the university level include psychometrics, multivariate statistics, industrial organizational psychology, and introduction to social psychology.
