Dr. Gershon is a leading expert in the application of Item Response Theory (IRT) in individualized and large scale assessments. He has developed item banks and Computerized Adaptive Testing (CAT) for educational, clinical, and health applications - including cognitive, emotional, and motor applications. He is currently principal investigator on three projects with the NIH - Toolbox for the Assessment of Neurological Function and Behavior, the NIH Roadmap Patient – Reporting Outcomes Measurement Information System (PROMIS) Technical Center and the National Institutes on Aging Genetic Norming project. He is also co-investigator and measurement development expert on numerous smaller projects including: NINDS sponsored project “Quality of Life Outcomes in Neurological Disorders” (Neuro-QoL), and the cancer-specific supplement to PROMIS.
