Dr. Maleki received her bachelor of science degree in chemistry and biology from the University of Tennessee. She received her Ph.D. in biochemistry and molecular biology at the University of Arkansas for Medical Sciences and completed post-doctoral work at Arkansas Children's Hospital in Structure, Function and Immunology of Peanut Allergens.
Dr. Maleki is currently a Research Scientist at the USDA focusing her work on peanut allergy and the reduction of peanut allergenicity through: processing, plant breeding and molecular biology. She is also working on understanding the structure and function of allergens, detection of allergens, and allergen immunology. Her overall accomplishments include: (1) the cloning, mutation, expression and purification of the myogenic transcription factors and defining the multiple thermodynamic equilibria that explains the interaction of these proteins with each other and with specific regulatory DNA sequences, which may lead to the use of these transcription factors in repair and rejuvenation of muscle; (2) high impact publications and two patent applications filed analyzing the relationship of the structure, function and immunological responses to the major peanut allergens; (3) studies involved in understanding and developing novel, T-cell mediated, immunotherapeutic treatments for peanut allergy; (4) being one of the first individuals in the field to perform high impact research describing the mechanistic relationship of thermal processing and allergenic behavior of food proteins. These studies were then taken to a more advanced level by unequivocally demonstrating that roasting enhances the allergenic properties of peanuts 90-fold over raw peanuts, alters T-cell stimulation and sensitization of mice.
Her awards include the American Peanut Research and Education Award in 2002, the Agricultural Research Service Early Career Scientist Award in 2003 and the Agricultural Reserch Service International Research Enhancement Award 2005. ARS-Post-doctoral research award, $100,000, 2007-2009. EPA award for Determination of clinically relevant cross-reactive epitopes of peanut and tree nuts $417,000 (2008-2010). USDA-Award for Primary and Secondary Prevention of Peanut and Tree Nut allergy, $4,000,000 (2009-2013).
She has been or is an invited member of the Food Allergy Advisory Committee to the FDA (2005) and Scientific Advisory Committee to the National Peanut Board, 2002-Present.
