S. Raza Shaikh, PhD
Dr. Shaikh currently is focusing his expertise on understanding how metabolites synthesized from dietary n-3 polyunsaturated fatty acids, known as specialized pro-resolving lipid mediators (SPMs) can be developed to enhance the function of antibody secreting B cells in pre-clinical and clinical models of health and disease. He also is working on ways to improve the function of mitochondria, which are the energy producing hubs in a cell. Finally, he is conducting a clinical study on diet and inflammation.
Dr. Shaikh previously was an associate professor of biochemistry and molecular biology at the Brody School of Medicine at East Carolina University. In 2012, he was awarded the Early Career Award from the International Society for the Study of Fatty Acids and Lipids for his research on n-3 fatty acids. In 2018, he received an award for his research from the American Society for Nutrition.

Dr. Shaikh has expertise in teaching lipid biochemistry, nutritional immunology and metabolism. He has previously taught graduate courses on medical biochemistry and nutritional metabolism.
Research in the Shaikh lab is broadly focused on understanding how dietary fatty acids and their metabolites regulate immunological and metabolic outcomes in obesity, Type 2 diabetes and cardiovascular diseases. The lab vertically integrates differing model systems including biomimetic membranes, cell culture, transgenic/knockout mice and human subjects. The lab uniquely fuses techniques from lipid biochemistry, membrane biophysics, and nutritional immunology to address questions related to the following major projects.
The first project aims to understand how metabolites known as specialized pro-resolving lipid mediators, which generally are deficient in obese subjects, can be used therapeutically to boost innate and adaptive immunity in pre-clinical and clinical models. Efforts focus on the mechanisms by which the metabolites target specific receptors to improve immunological responses mediated by B cells in addition to macrophages and select T cells.
Another project addresses how mitochondrial inner membrane structure-function is impaired in response to modifications to the mitochondrial-specific phospholipid known as cardiolipin. Investigation centers on how the remodeling of cardiolipin fatty acyl chains, as observed in Type 2 diabetes and cardiovascular diseases, impairs oxidative phosphorylation enzyme activity and the formation of mitochondrial structures known as supercomplexes.
Several additional projects currently are in development, including some epidemiological work and a phase I clinical trial is starting, which is focused on novel fatty acids and inflammation.
Dr. Shaikh is involved in organizing events and conferences for national and international meetings for differing societies. Dr. Shaikh currently serves on the editorial board for the Journal of Nutritional Biochemistry and Frontiers in Nutrition and is an associate editor of Prostglandins, Leukotrienes, and Essential Fatty Acids. Dr. Shaikh previously has done extensive work with diversity and inclusion initiatives.
