Ngoran Aristide Tehtinnyuy, a Cameroonian student, has recently made history by becoming the first international student to be recognised as the most outstanding graduate in the Graduate School of Engineering at Tokai University, Japan. This remarkable achievement comes after completing her master’s degree in civil engineering, where she authored a groundbreaking thesis titled “The Recycle of Paper and Plastic Waste in the Stabilisation of Weak Soils for Civil Engineering Construction Projects, Especially Unpaved Roads.”
Ngoran’s accomplishment not only shines a spotlight on her personal hard work and determination but also serves as a beacon of hope for Cameroonian students and aspiring engineers worldwide. “This achievement is not just for me but for every young Cameroonian striving to make a difference,” Ngoran shared. “It proves that with determination and access to quality education, we can compete on a global scale.”
Innovating for Sustainable Civil Engineering
Her thesis focused on a topic that aligns with the growing demand for sustainable construction methods. By exploring the use of recycled paper and plastic waste in strengthening weak soils, Ngoran’s research offers innovative solutions for addressing environmental challenges in civil engineering, especially in areas with unpaved roads.
A Message of Empowerment
Beyond the academic accolades, Ngoran is also passionate about encouraging other young people, especially girls, to pursue their dreams. She sent a powerful message: “To every youth, girl out there, there is something you were created for. Find that thing and press on. It’s not always easy, but persistence and the grace of God will make you triumph.”





Overcoming Cultural Shocks and Language Barriers
Like many students studying abroad, Ngoran faced a series of challenges, most notably the cultural shock and language barrier. “It took me six months to start familiarising myself with the Japanese culture,” she said. “I started making friends from all other continents and attended exchange programmes and webinars. I remembered that I can speak about 5 languages as a Cameroonian and tapped into that to start learning Japanese real quick—and it paid off.” Her resilience and willingness to adapt became key factors in overcoming these obstacles.
Looking Toward the Future of Cameroon
Her success highlights not only the potential of African students abroad but also the importance of nurturing talent that can contribute to development in their home countries. Ngoran strongly believes that Cameroon can benefit from integrating the technology and knowledge gained by students abroad. “I believe that if our leaders find ways to integrate the technology we learn abroad into local industries, it will drive sustainable development,” she said.
Ngoran Aristide Tehtinnyuy’s story is a testament to the power of education, persistence, and the global community. As Cameroon and the world look toward a future driven by innovation, her achievement serves as an inspiration for others to continue striving for excellence, no matter the barriers they face.
