Dear SIOP Nursing Network Members,

Thank you for voting in the recent elections for SIOP Nursing Network leadership posts. We are writing to update you on the results.


Congratulations to Dr. Courtney Sullivan on being re-elected Chair of the SIOP Nursing Network. Dr. Sullivan attained her Bachelor of Science in Nursing from Michigan State University. She earned both her master’s degree as an Acute and Continuing Care Pediatric Nurse Practitioner and Doctorate of Philosophy in Nursing from the University of Alabama at Birmingham (UAB). She is presently a postdoctoral research fellow at UAB where her research focuses on measuring pediatric oncology nursing quality and establishing an evidence-base of nursing-sensitive outcomes internationally. Her passion and focus are to support and enable nurses to improve practice and outcomes. Dr. Sullivan has worked with nurses internationally through St. Jude Global and other avenues for nearly a decade. While at St. Jude Global, she expanded its nursing outreach from 12 to more than 40 countries, transitioning from a twinning to a network approach. She established the Latin American Nurse Educator Network; St. Jude-VIVA Asia Pacific Nursing Institute; and co-led the development of the Association of Pediatric Hematology/Oncology Nurses (APHON) Spanish chemo/biotherapy certificate courses in Latin America and laid the groundwork for Portuguese and Russian versions. As past chair of the APHON Global Outreach Committee, she led strategic planning efforts and transformed the International Task Force into a robust and productive committee with several work streams. She is presently the SIOP Nursing Network Chair and has been active in the Young SIOP Educational Day Working Group, Membership Committee, Global Health Nursing Working Group, and Baseline Nursing Standards. Dr. Sullivan is also engaged in the WHO Global Initiative for Childhood Cancer (GICC) and is passionate about integrating nursing priorities within national childhood cancer control planning.
