Philosophy of Care

Dr. Bautista utilizes a comprehensive, evidence-based and team approach in her care of critically ill neonates and believes that shared-decision making and communication are key aspects to providing optimal, individualized care for each of her patients.

Clinical Interests

Dr. Bautista is a neonatologist with a special clinical interest in intestinal injury in the extreme premature population, including NEC and SIP, surgical diseases affecting the neonate including but not limited to short gut syndrome and related disorders, gastroschisis and intestinal atresias, as well as other complex congenital anomalies and syndromes.

Research/Academic Interests

Dr. Bautista’s research is focused on impaired gut motility and intestinal adaptation in the setting of prematurity and surgical diseases affecting the small and large intestine. She is particularly interested in the role of the mechanosensitive cation channel, Piezo1, in gut maturation and regulation of intestinal processes in specific gastrointestinal pathologies affecting the neonate. Dr. Bautista uses a basic/translational approach with conditional and inducible knock-out mouse models and human tissue correlates.
