Research summary

My long-term goal is to conduct mechanistic, patient-oriented research investigating circadian rhythms in pediatric airway and lung diseases such as asthma, obstructive sleep apnea, and lung infections. Specifically, I want to understand how circadian rhythm regulation contributes to disease pathobiology to develop novel therapeutic approaches to pediatric airway and lung diseases. Ultimately, the goal is to help answer questions like why do asthma exacerbations most often start at night? Why does cough worsen at night? And, how can we incorporate time of day into how we practice and understand disease?
