Improving solar fuel efficiency
Meet our new doctoral candidate Goutham Reghunadhan!
International - this is what the "I" in "IMPRS" stands for. It's also what doctoral candidate Goutham Reghunadhan values most about the community at our research school. Coming from India himself, Goutham joined the "Dynamic Spectroscopies" group of Prof. Jürgen Hauer at the Technical University of Munich at the beginning of this year. As a doctoral candidate, he is using ultrafast spectroscopy to investigate materials with potential applications in sustainable energy. Get to know him better in this interview!
What’s your main research focus for your PhD?
My PhD research addresses the global challenge of sustainable energy by exploring solar-driven methods to convert CO₂ and water into fuels. I focus on understanding electron transfer processes in photocatalysts based on metal-organic frameworks (MOFs), which show strong potential for efficient solar fuel production. Using Transient Absorption Spectroscopy and photocatalytic experiments, I study how these materials behave on ultrafast timescales to help improve their performance.
What excites you most about this field?
What excites me most is using transient absorption spectroscopy to track energy flow in materials at ultrafast timescales. The hands-on work of optimizing experimental setups provides both intellectual and practical challenges. Understanding these processes could contribute to more sustainable energy solutions.
What and where did you study?
I completed a dual BSc/MSc in Physics at IISER Mohali, India, with a Chemistry minor. My thesis with Prof. Arijit Kumar De focused on charge carrier dynamics in 2D perovskites using transient absorption spectroscopy. This experience provided the foundation for my current PhD work on MOF photocatalysts at TUM.
What attracted you to the IMPRS-APS program?
What stands out about IMPRS-APS is how it brings together researchers across disciplines to work on fundamental science. I appreciate how the program creates opportunities for regular exchange of ideas through seminars and workshops. Most of all, I value its international community - this diversity of perspectives consistently produces exciting science.
What skills do you want to develop during your PhD?
During my PhD, I aim to deepen my expertise in ultrafast spectroscopy techniques and complex data analysis. I also plan to strengthen my ability to communicate scientific results effectively. These skills will be essential for my growth as an independent researcher.
What is something you enjoy outside of research?
Outside of research, I maintain an active lifestyle through regular gym workouts and hiking. I also enjoy traveling to experience new cultures and environments. These activities help me stay balanced and bring fresh perspectives to my scientific work.
