ABOUT ME

Hi, there. Dr.Junle LIU earned his Ph.D. degree from Hong Kong University of Science and Technology (HKUST) at the Wind Engineering and Building Aerodynamics (WEBA) group and his Bachelor’s degree from Harbin Institute of Technology Shenzhen, at Artificial Intelligence for Wind Engineering lab. His supervisors are Prof.Tim K.T. Tse and Prof.Gang Hu.

Dr Liu, from May 2025, joined KTH FLOW Center as a postdoc research fellow supervised by Stefan Wallin focusing on ERC ROSAS project, and his research topics are centered on DRL and wall modelling.

In his past research journey, he has been concentrating on AI-aided aerodynamics and data-driven techniques in experimental fluid mechanics and numerical simulation. As of now, Dr.Liu has published papers covering AI-enhanced fluid mechanics, experimental fluid mechanics, and reduced-order modelling techniques in aerodynamics.

Some recent research interests of Dr.Liu:

• Wind Engineeirng: Experimental, Numerical, and Data-Driven perspectives;
• Reinforcement Learning for flow control and UAV/drone optimization (low-attitude aerodynamics);
• AI for Fluid Engineering: prediction, reconstruction, and control;
• Atmosphere aerodynamics

Dr.Liu welcomes any kind of academic and industrial collaborations. If you are interested in integrating AI techniques with engineering practices, please feel free to drop an email or send an instant message.
