His research interests are broad, encompassing both theoretical development and applied methodologies, including Computerized Adaptive Testing, Differential Item Functioning, Cognitive Diagnosis, and asymptotic properties in IRT. Many of his manuscripts were published in top-tier journals, ranging from very theoretical, such as Annals of Statistics, to very applied, such as Journal of Educational Measurement. He is the current President of the Psychometric Society, Editor-in-Chief of Applied Psychological Measurement, and a Fellow of American Educational Research Association. He has been included on the "Incomplete List of Teachers Ranked Excellent by Their Students" for the five consecutive years since 2008.



Brad Brossman

Brad holds the position of Research Psychometrician at the American Board of Internal Medicine (ABIM).  He conducts research on and implementing Computer Adaptive Multistage Testing (Ca-MST) for the ABIM examinations; investigating and enhancing the psychometric processes used to calibrate, score, and report the examination results; and collaborating with physicians concerning the psychometric quality and maintenance of the item pools for computer-based testing.

Prior to joining the American Board of Internal Medicine, Brad served as a Research Psychometrician in the TIMSS & PIRLS International Study Center at Boston College.  In this capacity, he conducted the operational psychometric components of the TIMSS and PIRLS 2011 administration, including estimating item parameters and aggregating country-level results using matrix sampling and plausible value methodology.  He also conducted research on these international exams, as he sought to enhance the TIMSS and PIRLS 2011 scaling methodology by designing new methods for estimating achievement trends on subdomains, estimating scale linking error, estimating and managing possible administration order effects, and estimating achievement for countries with scores exhibiting low reliability.
