My time in the doctoral program at Saitama University was one of the most formative periods of my professional and personal life, and it continues to shape how I work today as a university researcher in the United States. Looking back, I realize that the value of my experience at SU extended far beyond technical training—it provided me with a way of thinking, a global perspective, and a resilience that has been essential throughout my academic career.

During my doctoral studies, I was trained rigorously in plant molecular biology and genetics, with a strong emphasis on experimental design, data integrity, and scientific reasoning. At SU, I learned how to approach complex biological questions systematically—how to break them down into testable hypotheses, design appropriate experiments, and interpret results critically. This foundation directly supports my current role as a research scientist, where I independently plan projects, mentor students, manage laboratory operations, and contribute to collaborative research programs.

One of the most valuable aspects of my doctoral training was the emphasis on independence and responsibility. From an early stage, I was encouraged to take ownership of my research, manage my time effectively, and communicate my findings clearly. This mindset prepared me well for my postdoctoral work in Sweden and my current position at the University of Kentucky, where self-direction, problem-solving, and collaboration are essential. The ability to work independently while remaining open to feedback is something I developed strongly at SU.

Beyond technical skills, SU helped me develop a broad scientific perspective. My research on transcription factors and regulatory networks exposed me to systems-level thinking and feedback mechanisms—concepts that later influenced my interdisciplinary interests in environmental monitoring, sustainability, and instrumentation. Today, my work integrates molecular biology with engineering approaches, and I often reflect on how my doctoral training at SU taught me to think across scales, from genes to systems.

There are many memorable experiences from my time at SU. Conducting experiments late into the night, troubleshooting protocols that initially failed, and celebrating small breakthroughs with lab members are moments that still resonate with me. One of the most important challenges I faced was learning how to persist when experiments did not work as expected. These experiences taught me patience, resilience, and the importance of critical reflection—qualities that are indispensable in research. The supportive yet demanding research environment at SU helped me grow both scientifically and personally.

Equally impactful was the multicultural environment at Saitama University. As an international student, I was welcomed into a diverse academic community that included students and researchers from many countries and cultural backgrounds. This experience broadened my worldview and taught me how to communicate across cultural and disciplinary boundaries. Today, having lived and worked in Sri Lanka, India, Japan, Sweden, and the United States, I deeply appreciate how my time at SU prepared me to thrive in international research environments.

To students considering graduate studies, my advice is simple but important: choose a program that will challenge you, not just technically but intellectually and personally. Graduate school is not only about gaining knowledge; it is about developing habits of thinking, perseverance, and ethical responsibility. Embrace challenges, seek mentorship, and do not be afraid of failure—many of the most valuable lessons come from moments when things do not go as planned.

I also encourage students to remain open to interdisciplinary learning. The scientific and societal challenges we face today—whether related to environment, health, or technology—require perspectives that cross traditional boundaries. Use graduate school as an opportunity to explore, to ask broader questions, and to connect your research to real-world applications.

I am deeply grateful for the education, mentorship, and community I experienced at Saitama University. The doctoral program provided me with a strong foundation that continues to guide my work as a researcher, mentor, and collaborator. I am honored to be an alumnus of SU, and I hope my journey encourages current and future students to pursue their goals with curiosity, dedication, and confidence.
