Lixi Huang (in Chinese黃立錫) was born in Zhejiang province of China, educated at Beijing University of Aeronautics and Astronautics (BUAA) and University of Cambridge. His bachelor and master degrees from BUAA were in the field of aerospace engineering (jet propulsion), while the topic of his PhD study at Cambridge was theoretical acoustics and respiratory biomechanics (supervised by Prof JE Ffowcs Williams). He spent 8 years each in Beijing and Cambridge before coming to Hong Kong in 1996, initially at PolyU. After completing his PhD work in 1991, he worked as a research associate at the Whittle Lab (of turbomachinery), then as a college research fellow at Peterhouse, both within the University of Cambridge. His work on the mechanism of human snoring helped medical/surgical colleagues devise a successful laser surgery procedure in the early 1990s, and the related pursuit in fluid mechanics touched upon the fundamentals of fluid-structure energy transfer mechanisms. In 2017, he was the acting executive director for the University of Hong Kong Zhejiang Institute of Research and Innovation. Much of the research activity in mainland was funded by the provincial government and a national key fundamental research (973) project on aircraft noise led by Beihang University. Dr Huang is currently a full professor at HKU, teaching dynamics (with application to space flight), thermodynamics, aeronautical engineering, and acoustics. He serves as a subject editor for Journal of Sound and Vibration, an associate editor for Journal of the Acoustical Society of America, and an editorial board member for Chinese Journal of Acoustics.
His current research interests are focused on the use of electromagnetic forces in mechanics, broadband noise control, flow and thermal induced instability control, with applications ranging from home appliances, electronic cooling, to power plants and aerospace engineering.
