  • Biography

    Dr. Murphy is a physician-scientist with roles in both clinical and research laboratories. He has led the Seattle Children's Department of Laboratories as the Chief and Medical Director since 2023. The Department has 26 nationally recognized faculty and over 230 highly-trained and dedicated staff and conducts more than a million clinical assays and studies annually to support the care of children in the Pacific Northwest and beyond. Prior to this role, Dr. Murphy served as the Director of Clinical Microbiology at Seattle Children's since mid-2020 and as Assistant Director of Clinical Microbiology at the University of Washington since 2011. In addition to his experience in clinical laboratories, Dr. Murphy also leads a longstanding, multi-disciplinary research program focused on malaria vaccines and diagnostics. 

    Dr. Murphy did his B.S. at Iowa State University, where he studied Equine Infectious Anemia virus with Dr. Susan Carpenter. His malaria research began in 1997 when he started working on the burden of malaria with the late Dr. Joel Breman at the Fogarty International Center at the NIH. After a Post-Graduate Diploma in African Studies at the University of Cape Town, Sean obtained his MD/PhD at Northwestern University while studying erythrocyte lipid raft proteins and their role in Plasmodium infections with Dr. Kasturi Haldar. Sean completed a residency in Clinical Pathology at the University of Washington and a post-doctoral fellowship in malaria T cell immunology with Dr. Michael Bevan. Dr. Murphy is board-certified in Clinical Pathology.
