Leon Kasperek

Born and raised in Hannover, Germany, I developed a strong interest in physics and biology at an early age. Having difficulties in deciding between a career in medicine, biology or physics, my interest in mathematical approaches led me to study physics at the Leibniz University of Hannover.
In 2021 I joined the Biophotonics research group of Prof. Heisterkamp at the Institute of Quantum Optics and the Lower Saxony Center for Biomedical Engineering, Implant Research and Development (NIFE) in Hannover as a student assistant. My work includes performing laser laboratory experiments, cell culture tasks and improving fluorescence microscopy setups for imaging and optogenetic stimulation. During my Bachelor thesis in this group, I developed a widefield microscope for optogenetic stimulation of biological tissues. Working in this interdisciplinary group for years made me realize that I wanted to pursue a combination of physics and biology after my bachelor’s degree.
In 2024, I had the privilege of leading the iGEM-Team Hannover in the international iGEM Competition. Working in a multidisciplinary team, we developed an innovative synthetic biology project that enhanced my skills in interdisciplinary collaboration and deepened my growing fascination with molecular biology. This experience not only strengthened my belief in combining biology and physics, but also played a key role in my decision to pursue my Master’s thesis at ICFO in the Neurophotonics and Mechanical Systems Biology group to further connect physics with the living world.
Outside of the lab, I find peace and inspiration in aquatic environments – whether swimming, scuba diving or simply enjoying the peace of being by the water. I try to combine this love of water with my passion for travel, which allows me to explore new cultures, landscapes and perspectives, and to take advantage of opportunities to live abroad.
