Philosophy of Care

I believe in tailoring care to meet the needs of each individual patient by using approaches that combine established evidence-based practices with research-backed innovations. The best approach is one that involves open communication between the neonatologist, a multidisciplinary team of practitioners, and the patient’s family.

Clinical Interests

Dr. Stieren is a neonatologist who cares for critically ill newborns and infants in the Neonatal Intensive Care Unit (NICU). She has special clinical interests in developmental care of long-term NICU patients and management, discharge coordination, and follow-up of patients with medical complexity.

Research/Academic Interests

Dr. Stieren is interested in identifying predictors and early diagnostic markers of neurocognitive disorders so that interventions can be initiated as early as possible for these patients. She also has interest in monitoring and improving neurodevelopmental outcomes for former NICU patients.
