Research Projects

Bats emit ultrasonic pulses and use echolocation—listening to and analyzing reflected sounds from their surroundings—to perceive three-dimensional space, enabling real-time, high-speed flight navigation that surpasses current engineering systems. My research primarily focuses on the application of bat ultrasonic sensing from a comprehensive perspective encompassing mathematics, animal behavior, and engineering. I propose engineering applications by mathematically translating bat behavioral patterns and integrating them into actual devices such as drones, while also striving to understand the advantages of the unique biological functions hidden behind their behavior.

The appeal of research

"Under the banner of freedom and autonomy, grown adults engage in a battle of wits with the natural sciences." This is where I find the romance of research. Furthermore, once your findings are accepted as an international original research paper, you can search and read them anytime, anywhere on Google Scholar. These databases will not disappear even after we are gone. In other words, your living proof will remain forever as a small page in the history of human intellect. Don't you think there is value in that that makes it worth giving your all?
