I am an attending physician in both the divisions of newborn medicine and genetics and genomics. My ongoing research strives to understand how clinical genetics/genomic medicine can improve the care of high-risk neonates, from improving our understanding of infant mortality to providing early developmental supports for infants diagnosed with rare genetic disorders. I care for infants in the neonatal intensive care unit and I also see infants diagnosed with genetic conditions as outpatients in the NICU GraDS program in order to support optimal growth and development. In addition, I have a general genetics clinic and see inpatient consults on the genetics and metabolism service. In addition to my clinical research at Boston Children's Hospital, I also work in novel disease gene discovery and towards novel methods for genetic diagnosis with the Center for Mendelian Genomics at the Broad Institute of MIT and Harvard.

I received my medical degree from Harvard Medical School, after which I completed my pediatrics residency training with the Boston Combined Residency Program at Boston Children's Hospital and Boston Medical Center. I then pursued combined training in neonatal-perinatal medicine and in clinical genetics and genomics in order to develop my clinical expertise in both specialties.
