As a pediatric hospitalist and member of the inpatient complex care team at Cincinnati Children’s, I enjoy partnering with children and families in the hospital setting. I was drawn to hospital medicine because I enjoy caring for children of all ages as well as treating a wide range of medical problems. I also appreciate the incredible resilience of children and their families.

Outside of my clinical practice, I conduct quality improvement and patient safety research and serve as an assistant professor of pediatrics. I’ve completed a Master’s degree in clinical and translational research and have pursued advanced quality improvement science and leadership training through the Quality Scholars Program at the James M. Anderson Center for Health Systems Excellence.

My current research activities focus on improving diagnosis in pediatrics. My research aims to increase the ability to detect and learn from diagnostic errors in clinical practice and to improve our understanding of how diagnostic uncertainty impacts diagnostic outcomes. Additional ongoing work aims to improve communication of diagnostic uncertainty to patients and families to better engage them as critical members of the diagnostic team.
