Dr. Ramsden is a Clinical Investigator in the Intramural Program of the NIH and CAPT in the Commissioned Corps of the U.S. Public Health Service. Following completion of a medical internship and residency training, Dr. Ramsden was a clinical research fellow at UNC-Chapel Hill before joining the Intramural Program of the NIAAA in 2009. In 2016, he was appointed to a Clinical Tenure-Track position as the Head of the Lipid Peroxidation Unit, within the Laboratory of Clinical Investigation in the NIA in Baltimore, MD, with a joint Tenure-Track appointment in the Intramural Program of NIAAA in Bethesda, MD. Dr. Ramsden currently leads an interdisciplinary, translational research program investigating the roles of lipid mediators and lipid-related mechanisms underlying the pathogenesis of chronic pain and Alzheimer’s disease.
The objectives of the Lipid Peroxidation Unit are: (1) to delineate the roles of lipid peroxidation and lipid-related degeneration in age-related diseases, with an emphasis on chronic pain and Alzheimer’s disease, and (2) to translate discoveries into targeted, safe and effective diet and drug-based treatments. The Unit applies an interdisciplinary, translational approach— comprising randomized controlled trials, postmortem studies using traditional and multiplex immunohistochemistry, synthetic and analytical chemistry, and cellular models—to achieve these objectives.
