Dr. Allen’s research has primarily focused on two complementary interests, the function of the cerebellum and the neural basis of autism spectrum disorder, which he investigates using magnetic resonance imaging (MRI) and neuropsychological methods. In addition to these interests, he also conducts research investigating brain changes associated with aging, Alzheimer’s disease, and the treatment of dementia. Dr. Allen has received research grant funding from the National Science Foundation, the Cure Autism Now Foundation, Autism Speaks, and the National Institutes of Health.
