The research theme of Associate Professor Reiko Roppongi is the morphogenesis of synapses in memory and learning. A synapse is a contact structure between two neurons when information is transmitted from one neuron to the next in the brain. When she was a student in the Department of Information Engineering in the Faculty of Engineering, she enjoyed volunteering with children on the autism spectrum. It made her aspire to work in a role supporting these children and their families. She had two options: becoming a clinical psychologist or contributing through brain research. For her graduation thesis, she simulated neural transmission efficiency by programming neural networks. Gradually, she became fascinated by the intricacies of cells and chose the path of research. She pursued advanced studies in the Graduate School of Medicine, specifically in Cellular and Molecular Pharmacology, encompassing challenges in neuroscience and molecular biology. Since then, she has been relentlessly pursuing her dreams and achieving significant results.
