Dr. John Paul SanGiovanni serves in the Section on Nutritional Neurosciences in the Laboratory of Membrane Biophysics and Biochemistry at NIAAA. He is Associate Professor (Adjunct) in the Department of Biochemistry and Molecular & Cellular Biology at the Georgetown Medical School.

He trained as a scholar and researcher in neuroscience, visual psychophysics, nutritional biochemistry, biostatistics, and epidemiologic research design at Harvard University, Brandeis University, and Boston College.  At present Dr. SanGiovanni is applying an integrative omics approach to the study conditionally essential brain-resident nutrients in their capacity to affect brain and retinal cellular signaling systems – systems known to act in atrophic and neovascular retinal diseases, substance use disorders, and schizophrenia.  He has active collaborations with research teams at Harvard Medical School, McGill University, University of Montreal, University of Bristol, Universita Cattolica del S. Cuore, MAGI, and Bascom Palmer Eye Institute.    

Dr. SanGiovanni has worked continuously in the field of retinal and brain science for over 30 years, holding positions at the Harvard Medical School (11.5 years), the International Nutrition Foundation (2 years), and The National Institutes of Health (16 years).  He served in key leadership roles as scientific project officer and analysis team leader for two multi-center phase III clinical trials funded at more than $25M each. These trials resulted in NIH-issued public statements on standards of care and FDA approvals (Preservision ®).   He has served on numerous technical expert panels for AHRQ and NCCAM.  He has chaired the Members in Training Committee at ARVO.

Dr. SanGiovanni received the NIH Director's Award from Dr. Elias Zehouni in 2008 and Dr. Francis Collins in 2011 for his roles in large-scale genomics projects.  He received the Early Career Award from the International Society for the Study of Fatty Acids and Lipids (ISSFAL) in 2010 and was a finalist for the Sigma Xi Young Investigator Award the year before.

Dr. SanGiovanni has published in ScienceNature MedicineScience Translational Medicine JAMAPNASJ. Neurosci.Pediatrics, and American Journal of Clinical Nutrition.  As of March 2017, he has ~12,200 citations, an i10-Index of 40, and an h-Index of 32.
