The Making of a Researcher: Reflections from a Doctoral Journey
A PhD is much more than completing a thesis. It is a journey of learning, questioning, improving, and gradually becoming an independent researcher. Looking back, I am grateful for everything I have experienced since beginning my doctoral studies three years ago at Aalto University School of Engineering. My journey began with a simple email to my supervisor, Professor Sanna Syri, asking about research opportunities in her group. I have recently submitted to pre-examination my doctoral thesis, which focuses on power system modelling and the integration of variable renewable energy in the Nordic-Baltic region.
A major part of my doctoral work was carried out within the RealSolar project, which became one of the most valuable experiences of my PhD. Through RealSolar, I connected my research on power system modelling with broader discussions on solar energy development in Finland. The project also gave me the opportunity to collaborate with experts working on bifacial solar technology.
One of the key lessons I learned during my PhD is that research is not only about producing results, but also about communicating them clearly. Writing research articles and presenting at international conferences helped me share my work, follow recent developments in the field, and connect with researchers from around the world. Presenting at RealSolar consortium meetings also strengthened my ability to explain technical results to audiences with different areas of expertise. The questions and feedback I received encouraged me to consider new perspectives and think more carefully about how research can support practical discussions on future energy systems.
I feel fortunate to have a supervisor who was supportive, encouraging, and available when I needed guidance. At the same time, I was given the freedom to develop my own ideas, make decisions, and grow as an independent researcher. This balance between support and independence made a significant difference throughout my PhD.
During my doctoral studies, I also worked with a commercial power system modelling tool, which has been valuable for both my research and future career. With the guidance of my advisor, Dr. Jaakko Jääskeläinen, I began developing a Nordic-Baltic power system model, which was later adapted for the aims of each publication. It has been especially rewarding to see this initial work used and further developed by colleagues in our research group.
I am originally from Sri Lanka, and before coming to Aalto, I completed my master’s degree at the University of Oulu. Moving between different environments and cultures can be challenging, but I now see this as an essential skill I expertise during this time. I have truly enjoyed living and working in Finland, where I learned to balance the productivity, wellbeing, personal life, and hobbies.
In the end, the greatest outcome of my PhD is not only the thesis I completed, but the person I became along the way. I am grateful to my supervisor, advisor, research group, and the RealSolar project for making this journey so meaningful.
