Jialei studies aerodynamics behind birds’ flight using computational fluid dynamics (CFD) approach. The study aims to find out the tactics that birds adopt to achieve the remarkable flight performance.
Jialei graduated from University of Science and Technology of China (China) in 2011 with BS degree in theoretical and applied mechanics. He continued his study at Vanderbilt University (USA) and earned a PhD in mechanical engineering in 2016. Later, he joined a robotics group in The Chinese University of Hong Kong (Hong Kong) as a postdoctoral researcher. He starts the current role in 2018.
Jialei’s research focuses on the mechanisms of animal locomotion in fluid, like birds/insects flight and fish swimming, using computational fluid dynamics approach. Now he is exploring the aerodynamics of large birds at different flight modes (gliding, flapping) and at different motions (forward flight, hovering, rotating). His previous research includes the fluid dynamics of hummingbirds’ flight and fish undulatory swimming.

We are measuring dynamic morphing in bird wings using modern computer vision approaches to develop dynamic three-dimensional surfaces. Using these models, we are exploring kinematic patterns of force generation, identifying mechanisms of gust rejection and recovery, and performing computational fluid dynamics to understand how forces are produced and distributed. These results will shed new insight into the interplay between passive/active wing morphing and aerodynamic force generation and may lead to a new generation of aircraft.
