Dr. Davidson's major research interests include: Aging and Developmental Disabilities; Behavior Disorders; and Neurotoxicants and Development.

Philip W. Davidson, PhD is working with Gary Myers, MD, to study the effects of transplacentally transmitted methylmercury (MeHg) on child development. Ocean and lake fish ingest methylated Hg++ and store it in fatty tissue. Humans ingesting fish through dietary intake, therefore, are exposed to MeHg, known to be a CNS toxin and a teratogen. Eating only a few meals of fish per month may raise MeHg to levels that exceed the WHO standard. Recent studies have indicated that low-dose exposure may present a toxic stimulus in utero and affect the development of those offspring of mothers who eat fish during pregnancy. The study is focused on developmental outcomes in older cohort of children and young adults prenatally exposed to MeHg in the Republic of Seychelles.

Dr. Davidson is also studying the characteristics of persons with developmental disabilities. Little is known about the health outcomes as persons with developmental disabilities age. Dr. Davidson is working with an international team with investigators on a project to ascertain health status amoung cohorts of older adults and elderly adults. Between 10%-30% of persons with developmental disabilities are believed to have psychiatric disorders. Among the most contentious of these so-called dual diagnoses is the coincidence of mental retardation and aggressive or assaultive behavior. This cohort of individuals is rarely able to live in community settings and often must live and work in overly restrictive environments.
