Research interests are varied, but center on the relationship of the brain to behavior. There are several research projects investigating normal function and function in impaired populations: Patients with Alzheimer’s Disease, Huntington’s Disease, Down’s Syndrome, the elderly, head trauma patients, normal children, children with head trauma, and whatever new populations become available to provide a window to the functioning of the brain.

The techniques used in the laboratory range from neuropsychological and psychophysical testing to recording the brain’s event-related potentials and functional MRI.

There is particular interest in neurodegenerative diseases (Alzheimer’s Disease and Down’s Syndrome, for example) and their effects on sensory and cognitive function in the brain.

Collaborative Efforts: Are underway with investigators at the Alzheimer’s Disease Research Center, the Genetic Disorders Clinic, and the Head and Neck Surgery Department at UCSD, as well as the EEG experts at Scripps and the neuropsychologists and MRI experts at UCSD and the VA. One of the benefits of doing research in San Diego is the existence of good opportunities for collaboration.

Scholarly Areas
I focus on studies of the etiology of health-related behavior following the Behavioral Ecological Model. This includes studies of classic risk practices, such as diet and physicial activity, as well as studies of clinicans’ service delivery. It also addresses means by which the influence of and change in culture can be achieved to establish healthy practices in whole populations.

Dr. Hovell holds a PhD in Child Psychology and Human Development with specialization in adolescent development from the University of Kansas and a postdoctoral MPH in Social Epidemiology from the University of California at Berkeley. Dr. Hovell is the former and founding Head of the Division of Health Promotion.
