Title: Tenure Track Investigator
Office(s): Lipid Mediators, Inflammation, and Pain Unit (HNN-25)

Dr. Ramsden is a Clinical Investigator in the Intramural Program of the NIH, Commander in the Commissioned Corps of the U.S. Public Health Service (PHS), and Adjunct Faculty at UNC-Chapel Hill. After completing a medical internship and then residency training in Physical Medicine & Rehabilitation at the Rehabilitation Institute of Chicago, he 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 leads an interdisciplinary, translational research program investigating the roles of lipid mediators and lipid-related mechanisms underlying the pathogenesis of age-associated diseases, with an emphasis on chronic pain and neurodegenerative conditions. Dr. Ramsden also serves as Chief Medical Officer for PHS-1 Rapid Deployment Force team of the Commissioned Corps.

Research Topics

The objectives of the Lipid Peroxidation Unit are: (1) to discover new mediators and mechanisms linking lipids to age-associated diseases, with an emphasis on chronic pain and Alzheimer’s disease, and (2) to translate these discoveries into targeted, safe and effective diet and drug-based treatments. The Unit applies an interdisciplinary, translational approach—comprising randomized controlled trials, non-randomized and postmortem studies, missing data recovery, synthetic and analytical chemistry, animal models, immunohistochemistry, and cellular and ex vivo assays—to achieve these objectives.
