Overview
As an allergist and immunologist, and the spouse of someone with a food allergy, I bring both professional expertise and personal insight to my work. I am passionate about improving the quality of life for those with asthma, eczema, and food and environmental allergies. Having firsthand experience with the real-world challenges of managing allergic conditions, I take a collaborative approach to care, partnering with families to develop treatment plans that are not only effective, but also practical and aligned with their goals. I also have the privilege of caring for children with primary immunodeficiencies, including severe combined immunodeficiency and congenital athymia. My research focuses on optimizing newborn screening guidelines for these conditions, particularly in premature infants. I am committed to advancing treatment strategies and providing compassionate support to families navigating these complex conditions. Outside of work, I cherish time with my spouse and two children and take every opportunity to enjoy the outdoors.
