Research Interests

Animals alter their behavior to respond to the demands of changing circumstances. We have investigated the design principle of neuronal mechanisms underlying adaptive behavior including social adaptability in animals. We focus on how animals decide their behavior depending on their circumstance and previous experiences. Aggressive behavior in insects provides great model systems to investigate the neuronal mechanisms underlying emerging adaptive behaviors. We focus on insects and some kinds of invertebrate animals to investigate neuronal mechanisms of adaptive behavior since they have relatively simple and identical nervous systems. From comparative neurophysiological research, we deepen our understanding of the adaptive behavior of animals, which helps us to develop biology and biological-inspired technical innovations.

Research Focus

1. Neuronal mechanisms underlying aggressive behavior and escape behavior of animals
2. Biomechanics of ultra-fast movements of insects
3. Effects of electromagnetic field on insect nervous systems
