Eric Garber
Eric A. E. Garber, Ph.D., Senior Research Scientist
Center for Food Safety & Applied Nutrition
Food and Drug Administration, College Park, Maryland  USA

Dr. Garber has been a research scientist with the FDA since 2002. He oversees the application and development of immunodiagnostic methods for the detection of food allergens. Recently, this has included the development of a novel xMAP-based multiplex assay for the simultaneous detection of 15 food allergens plus gluten with built-in confirmation based on the use of multiple assays per analyte and two extraction protocols. Major advantages of this novel approach include an ability to distinguish between homologous cross-reactive analytes, normally indistinguishable using the currently used commercial ELISA test kits, and more efficiently respond to growing needs associated with the high prevalence of people with multiple food allergies. While with the FDA, Dr. Garber also developed antibody-based methods adopted by the Food Emergency Response Network (FERN) for the reliable detection of proteinaceous select agents (i.e., abrin and ricin) in food. Prior to joining the FDA, Dr. Garber worked on the development of immunodiagnostic assays for infectious agents, the detection of endocrine disruptors in the environment, and arsenic biochemistry. His training is in protein biochemistry, kinetics-thermodynamics, and redox biochemistry. Prior to joining the government, Dr. Garber worked in industry, was a professor of biochemistry at a small liberal arts college, and briefly worked in academic administration overseeing the establishment of a master’s degree program in biotechnology.  Dr. Garber received his B.S. in Biochemistry from The City College of New York, Ph.D. in Biochemistry from Brandeis University, and conducted post-doctoral research at Northwestern University.
