International research exchanges play an important role in developing the next generation of African scientists by exposing them to global expertise, advanced research environments, and diverse scientific cultures. At AIMS South Africa, students are encouraged and supported to participate in such opportunities as part of their academic and professional development. These experiences strengthen research skills, broaden perspectives, and deepen students’ commitment to advancing scientific innovation on the African continent.

Building on the intensive Introduction to Radiobiology course held at NRF-iThemba LABS in August 2025, AIMS South Africa MSc research student Marry Thekhwe continued her training through a research visit to the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, from January 19 to February 7, 2026. The visit strengthened both the computational and radiobiological aspects of her research. Accompanied by her main supervisor, Dr Thifhelimbilu Daphney Bucher (University of Cape Town), an AIMS South Africa 2006 alumnus, Marry undertook specialised training in computational modelling and radiobiology with Dr Batmunkh Munkhbaatar at the Laboratory of Radiation Biology.

Marry’s MSc research focuses on FLASH proton therapy for the future UCT Proton Therapy Centre. Her work aims to identify which patients and cancer types could benefit most from this emerging treatment approach, which has the potential to deliver radiation doses more safely and effectively than conventional radiotherapy methods.

During her time at JINR, Marry received advanced training in Monte Carlo simulations, FLASH radiation modelling, and radiobiological modelling using the Geant4-DNA toolkit. She learned how to simulate particle track structures within cells and quantify DNA damage caused by proton radiation, linking her laboratory-based knowledge with powerful computational frameworks. This experience broadened her perspective and strengthened her ability to investigate the potential of FLASH proton therapy.

The visit also provided Marry with the opportunity to explore JINR’s advanced research infrastructure and to attend seminars with international scientists working in radiation biology and related fields. She engaged with researchers from South Africa conducting experimental projects at the institute, creating valuable opportunities for knowledge exchange and collaboration.

"What stood out most for me was the culture of kindness, openness, and knowledge sharing at JINR. The researchers were incredibly accommodating and supportive, always willing to help and engage in meaningful dialogue. This atmosphere encouraged creativity and collaboration and left a lasting impression on me." - Marry Thekhwe

The combination of hands-on laboratory training at iThemba LABS and advanced computational modelling at JINR proved transformative for Marry's research development. These experiences not only enhanced her technical skills but also highlighted the importance of supportive, collaborative scientific environments in advancing innovation.

"Special thanks to the UCT Research Support Office and AIMS South Africa for their travel support. I am also deeply grateful to my supervisor and co-supervisors, Dr Daphney Bucher and Steve Peterson (UCT), and Dr Rejoyce Gavhi-Molefe (AIMS South Africa), for their guidance and mentoring throughout my research journey. My sincere appreciation also goes to Dr Batmunkh Munkhbaatar (JINR) for hosting us." - Marry Thekhwe

Marry’s journey reflects the value of combining foundational laboratory training with exposure to cutting-edge computational methods. Such international collaborations continue to play an important role in strengthening African research capacity and preparing young scientists to address global challenges in radiation science and medical innovation.
