I study the frequency, causes, and consequences of developmental disabilities (such as autism, cerebral palsy, and fragile X syndrome).

I’m passionate about using data to better understand the situations of persons with disabilities. I’m also interested in improving the availability of the tools used to measure and assess disability. I created DisabilityMeasures.org to help disseminate freely-available research and assessment tools.
