Dr. Daehyun Choi is a postdoctoral researcher at Georgia Tech who has expanded the frontiers of modern fluid mechanics, including turbulence, two-phase flow, and fluid-structure interaction. His research further explores extreme behaviors in aquatic animals and humans through field studies and robotic design, aiming to develop groundbreaking propulsion techniques. His projects are supported by DARPA and the National Research Foundation of Korea.
He earned his Ph.D. degree in the Department of Mechanical Engineering at Seoul National University in 2022 under
the supervision of professor Hyungmin Park.
In the same department, He received M.S., and B.S. degrees in 2018, and 2015, respectively. He also
received the best Ph.D. thesis award at Seoul National Univerity.
