Before coming to Boston University she served as both a Clinical Fellow and a Pediatric Health Services Research Fellow at Boston Children's Hospital. Early on in her career, she was singled out for her prowess as an educator and as a medical resident. This trend has continued as she constantly seeks to innovate the medical industry such as developing clinical guidelines for apnea of prematurity and criteria for discharge. Dr. Parker also mentors students, gives lectures, and serves an Investigator for clinical trials.
