For Global Child Health student Taiye Ibiyeye, mentorship has been a defining part of her graduate school journey, one that transformed curiosity into purpose and coursework into research with real-world impact.
As a pediatric surgeon at the Federal Teaching Hospital Lokoja in Nigeria, Ibiyeye entered the health economics course with limited knowledge of the field. What began as a new and challenging subject quickly became the foundation for her thesis, focused on the cost-effectiveness of centralized and decentralized childhood cancer care in Nigeria. Ibiyeye’s research is especially relevant in Nigeria, a country with limited healthcare resources. As Nigeria becomes a newly designated focus country within the WHO Global Initiative for Childhood Cancer, the growing national and international attention on strengthening childhood cancer care emphasizes the importance of her work.
That shift was guided by her thesis chair and mentor, Nancy Boulos, MD, whose expertise and steady support helped Ibiyeye navigate unfamiliar territory with confidence. As an instructor in Health Economics at the Graduate School of Biomedical Sciences and a senior research scientist, Bolous brings deep experience in costing and cost-effectiveness analyses of interventions in hematology and oncology.
Through constructive feedback, patience and clear guidance, she’s helped Ibiyeye break complex ideas into manageable steps. Bolous supported Ibiyeye throughout the development of her thesis proposal and will continue to mentor her as she carries out the project. For Bolous, effective mentorship means meeting students where they are. Drawing from her own transition from clinical medicine into health economics, she emphasizes patience and perspective.
“It’s about holding their hand at the beginning and reminding them to trust the process,” Bolous said. “When they look back, they realize just how far they’ve come.”
Together, Ibiyeye and Bolous exemplify how mentorship within the St. Jude Graduate School supports students as they develop the skills, confidence and vision needed to pursue research with long-term impact in their home countries.
