Biography & Affiliation


My research focuses on T-cells, type 2 inflammation and allergies. I work to identify molecular mechanisms for Th2 cytokine production, and Th2 differentiation and activation. With my research, I aim to find a cure for human atopic disorders, including eosinophilic esophagitis (EoE).

I have helped to characterize the unique, tissue-specific transcriptome of purified murine eosinophils under homeostasis and allergic conditions. I have also demonstrated the expression and function of certain unexpected molecules, CD22 and CAR4, on gastrointestinal and lung eosinophils, respectively.

I developed a murine eosinophil transfer model system that is useful in assessing the function of genes of interest that are expressed on eosinophils or other target tissues. I am also the co-inventor of the EoE Diagnostic Panel (EDP), licensed to the diagnostic company Diagnovus, LLC. The EDP is an Engauge GI-EoE test currently used in clinical practice.

I have received several awards, including:

  • 2011 American Academy of Allergy, Asthma, and Immunology Fellow-in-Training Travel Award
  • 2013 Ohio River Valley Cytometry Association Imaging and Cytometry Research Symposium Outstanding Poster Presentation, 2nd Place
  • 2014 Ohio River Valley Cytometry Association Imaging and Cytometry Research Symposium Outstanding Poster Presentation, 1st Place

I have also co-authored two book chapters and have been an invited speaker for several national and international meetings related to eosinophilic disorders.
