Interview with MBF Fellow Dr. Marina Caballero Bellón

Dr. Caballero Bellón from Barcelona, Spain, is the 11th MBF Neuro-Oncology Fellow, joining the Brain Tumour Research Centre team from 2024 to 2025. During her fellowship, she immersed herself in a world-class environment where researchers and clinicians work side by side, gainin

g invaluable experience in translational paediatric brain tumour research. We spoke with Dr. Caballero Bellón about her journey, the insights she gained, and the global impact of the MBF Fellowship.

How has your experience at the Brain Tumour Research Centre shaped your perspective on paediatric brain tumour research?

My time at the Brain Tumour Research Centre has been truly transformative. Being immersed in a leading-edge environment where clinicians and researchers work side by side has deepened my understanding of how complex, yet urgent, paediatric brain tumour research is. I've gained a greater appreciation for the importance of translational research—bridging discoveries in the lab directly to patient care. It has reinforced my belief that advancing treatment requires not just scientific innovation, but also a collaborative, patient-centred approach.

What has been your biggest takeaway from the Fellowship as you look ahead in your career?

The most significant takeaway from this Fellowship has been the value of interdisciplinary and international collaboration. Working alongside top-tier professionals from various backgrounds has shown me that progress in paediatric neuro-oncology doesn’t happen in isolation—it thrives on shared knowledge and diverse perspectives. This experience has solidified my commitment to continuing research and clinical work in a global, team-driven setting.

What drew you to the Meagan Bebenek Neuro-Oncology Fellowship at SickKids?

What initially drew me to the Meagan Bebenek Neuro-Oncology Fellowship was the opportunity to be part of one of the world’s foremost institutions in paediatric care. SickKids’ reputation for innovation, combined with its compassionate approach to treating children with brain tumours, resonated deeply with my values. I was particularly inspired by the Fellowship’s focus on both clinical excellence and research, and the chance to learn in an environment that prioritizes impact, mentorship, and hope.

What inspires you to dedicate your career to paediatric neuro-oncology?

Working with children facing brain tumours is both humbling and motivating. Their resilience and the courage of their families remind me daily of the importance of what we do. I’m inspired by the chance to make a tangible difference—not just by improving survival, but by enhancing the quality of life for these young patients. The challenges in this field are great, but so is the potential to create meaningful change.

What gives you the most hope for the future of paediatric brain tumour research?

What gives me the most hope is the momentum I see in the field—from advances in molecular diagnostics and precision therapies, to the growing networks of researchers, clinicians, and families advocating for change. There is a rising global commitment to invest in paediatric brain tumour research, and more than ever, we're seeing a convergence of technology, collaboration, and compassion that can truly transform outcomes. That hope is what drives me forward.

Thank you, Dr. Caballero Bellón, for sharing your experience and invaluable insights with us. Her journey highlights the impact of the MBF Fellowship in shaping the next generation of leaders in paediatric neuro-oncology.
