I completed Allergy and Immunology fellowship training at the Massachusetts General Hospital after residency training in Internal Medicine at the University of Chicago and obtaining my medical doctorate from the University of Maryland. Prior to this, I obtained my BA with honors from Johns Hopkins University and also researched cancer vaccine development at the Johns Hopkins School of Medicine. Currently, my basic and translational research focuses on innate and T cell immune responses in allergic diseases, particularly asthma. I have also helped identify a novel chemokine ligand-receptor interaction that is important in allergic diseases, the results of which are published in the Journal of Experimental Medicine. My research has been supported by the NIH, including the T32 as a mentored post-doctoral fellow, the F32 as a principal investigator, and the AADCRC U19 as a scientist. I have also published in Science Translational Medicine, the Journal of Clinical Investigation, the Journal of Allergy and Clinical Immunology, and the Journal of Immunology and have received recognition within the field with a American Academy of Asthma, Allergy, and Immunology Mechanisms of Asthma and Allergic Inflammation Featured Poster. I am also an attending physician at MGH Allergy Associates and the MGH Clinical Immunology Laboratory.
