Pediatric Critical Care Research

  • Sara Aghamohammadi, M.D.

    Dr. Aghamohammadi’s research interest includes long-term outcomes and standardizing care with the use of treatment protocols as related to pediatric critical care medicine. Her involvement with the Society of Critical Care Medicines PICU Liberation program has led to the development of quality improvement measures and standardization of ICU practices, such as pediatric early mobility, nursing-driven sedation protocol, and best practices for use of high-flow nasal cannula, at UC Davis Children’s Hospital.

    Dr. Aghamohammadi was appointed Chief Wellness Officer in July 2022 and is passionate about advocating for and supporting clinician wellbeing efforts throughout UC Davis Health. Her academic interest in medical humanities led to the integration of improv and medical education through med improv workshops and curriculum development that she hopes to expand through the health system.
