Biography

My current research focuses on both theoretical development and applications of item response theory (IRT). These include computer-based assessment, automated test assembly (ATA), differential item functioning (DIF), cognitive diagnostic measurement, and patients reported outcome. Today one of the main challenges in Educational Measurement is to develop theories and methods for the new mode of large scale implementation of computerized assessment. More recently I have been concentrating on developing item selection methods for computerized adaptive testing (CAT). Several new methods have been developed, such as the a-stratified method, the global information method, and the constraint weighted information (CWI) method.

I am a practitioner-turned-professor. I had nine productive years in the testing industry, from 1992 to 2001, as a Senior Psychometrician at the National Board of Medical Examiners (NBME), Philadelphia, PA, and as a Research Scientist at Educational Testing Service (ETS), Princeton, NJ.

I am also interested in many other aspects of assessment, such as Test Equity, Test Security, and Patient-Reported Geriatric Depression Outcomes. In 2005, I received Fulbright Senior Specialist Award from US State Department. In October 2006 I was selected as Public Presenter by American College Testing, Inc. (ACT), Iowa City, IA.
