Pediatric Oncology, Palliative Care, Outcomes Research

As a pediatric oncologist, I have a particular interest in cancer-related communication as a model for all difficult conversations. Much of my work focuses on communication about the cancer diagnosis, cancer treatment decision-making, and the transition to palliative care, where communication can have a major impact on the care that unfolds at the end of life.  I have developed clinical expertise in communication through dedicated inpatient and outpatient care of childhood cancer patients, created a body of research that defines specific attributes and outcomes of high quality communication, and trained pediatric hematology/oncology fellows and other physicians to communicate effectively with patients and families.
