As a member of the Association of Pediatric Hematology/Oncology Nurses (APHON) Global Outreach Committee and the Spanish sub-Committee, Julia co-led a comprehensive initiative offering the APHON Chemotherapy/Biotherapy Provider Course in Spanish across Latin America, in person and during the pandemic in 2020, virtually. By the end of 2021, 29 Spanish-speaking Latin American course instructors and more than 400 nurses from over 70 hospitals in 19 Latin American countries had been trained through the initiative.

As past co-chair (and now member) of the International Society of Paediatric Oncology (SIOP) Pediatric Oncology in Developing Countries (PODC) Committee, Julia has worked with colleagues from across the globe who are members of the Working Groups addressing such issues as Essential Medicines, Training and Education, Nursing, Adolescent and Young Adults, and Patient and Family Engagement. This network of volunteers has written multiple publications including position statements, guidelines, and protocols for use in LMIC. A name change in 2024 to Global Health Network (GHN), brought a broadening of the scope of the former PODC. Julia continues her work through the SIOP GHN Global Mapping Programme to locate and map childhood cancer facilities around the world. The GHN ongoing advocacy for childhood cancer care in settings of great disparity has brought increased attention to childhood cancer as a priority in national cancer control plans.

Julia's past work as the SIOP Advocacy Officer led to a successful effort to gain WHO non-state actor in official relations recognition for SIOP (achieved in 2018). This then expanded to her collaboration in three workshops on childhood cancer in 2016 held in conjunction with WHO and CCI in Ethiopia, Myanmar and Ghana. Other tasks include a continued liaison role with WHO Headquarters in the area of Non-Communicable Diseases, e.g., SIOP advocacy on childhood cancer text in the current WHO draft Cancer Resolution (2017). Current service includes membership in the SIOP WHO Non-State Actor in Official Relations Committee and efforts directed by the SIOP WHO work plan and WHO Global Childhood Cancer Initiative begun in 2018 to address disparities in access to care in LMIC.

As the past SIOP Secretary General, and current society member, her role includes expanded service to the Society, partners and stakeholders to improve global access to treatment and care of children and adolescents with cancer and address issues of survivorship. This work includes a focus on supporting efforts to achieve universal health care and advocacy in all aspects of childhood cancer.

Additional current activities include English copy-editing for academics preparing manuscripts and grant proposals from various universities in Europe and oncology nurses in LMIC. Julia is also a contributor to Oncopedia articles on pediatric oncology nursing on the Cure4Kids website based at St. Jude Children’s Research Hospital in the U.S.A.
