About Me
I always knew that I wanted to be a pediatrician, and during my pediatrics residency training I became drawn to caring for infants. In my role as a neonatologist, I direct my patients' medical treatment in partnership with the rest of the care team, including other doctors and practitioners, nurses, therapists and most importantly, my patients' families. It is truly a privilege to care for sick infants and their families at birth and beyond.

Clinical Focus and Research
My research focuses on pharmacology and infectious diseases in infants. I am interested in how drugs affect infants differently from older children and adults. I am also exploring how infections impact infants in the neonatal intensive care unit and what strategies can reduce the risk for developing infections.
