Frequency Biology Project

I have long been interested in resources and energy, as they are essential for everyone, regardless of individual preferences. In the coming years, I believe that interest in the ocean—where vast untapped resources lie—will continue to grow. However, observation in remote areas such as the deep sea remains technically challenging, and scientific understanding of its impact on ecosystems and carbon cycles is still limited. I began to focus on plankton and benthic organisms, which are highly sensitive to environmental changes, and considered the possibility of detecting variations in their behavior and biomass using advanced sensing technologies. When I observed plankton collected with a net in an aquarium, I noticed that each species displayed distinct movement patterns. This observation inspired the concept of a new behavioral biology, "Frequency Biology," which captures biological activity at the millisecond scale. Based on this concept, I initiated research to directly observe marine particles. Moving forward, I aim to advance this work toward practical implementation through continued research and development.
