Portrait of Karen Laky, Ph.D.


Dr. Laky received a doctorate of philosophy in biomedical science from the University of Connecticut, for research on the role of cytokines in intra- and extra-thymic T-cell differentiation and homeostasis. In 2000, she started a postdoctoral fellowship in the laboratory of Dr. B.J. Fowlkes in the NIAID Laboratory of Cellular and Molecular Immunology. In 2008, she was appointed staff scientist. During her time in the T-Cell Development Section, she studied the role of Notch and T-cell receptor signaling in T-cell lineage commitment, selection, activation, differentiation, and effector function. In 2015, Dr. Laky joined the Food Allergy Research Unit as a staff scientist, where she continues her interest in mucosal immunology by characterizing the cellular mechanisms responsible for the high prevalence of food allergy, eosinophilic esophagitis, and elevated IgE associated with Loeys Dietz syndrome and elucidating the roles of diet and microbiome on the development of allergy.
