Raymond F. Palmer, Ph.D.
Principal Investigator/Faculty Program Director
As a biostatistician/epidemiologist trained in Preventive Medicine, Raymond F. Palmer, Ph.D., has extensive experience in health promotion disease prevention research. As an NIH funded principal investigator in autism epidemiology, his work is focused on investigating environmental influences to understand the etiology of autism spectrum and other neurological disorders.
For the past decade, Dr. Palmer has collaborated with Dr. Claudia Miller in studying the relationship between environmental exposures and the risk for autism — specifically environment exposures that may also underlie TILT. Dr. Palmer developed a deep understanding of how to use the Quick Environmental Exposure and Sensitivity Inventory (QEESI) in research through his study comparing QEESI scores of mothers who have children with autism and mothers of typically developing children. This work shows that TILTed mothers are three times more likely to have a child with autism compared to mothers who are not TILTed.
Dr. Palmer is a former nurse, has a Master’s degree in psychology, and holds a Ph.D. in preventive medicine from the University of Southern California. He is currently a professor in the Department of Family and Community Medicine at The UT Health San Antonio. Dr. Palmer is director of the Hoffman TILT program where he is responsible for the scientific integrity and oversight of daily operations and progress in each phase of the project.
