I am continuously seeking potential PhD candidates, Master’s graduates, Postdocs, and exchange PhD students to join my team. If you are interested in research on building acoustics, environmental noise control, acoustic metasurfaces, or other acoustics-related areas, please send your CV, transcript, and list of publications to me via email at liangfen.du@polyu.edu.hk

I also provide consultancy services in various acoustic-related areas, including Noise Impact Assessment, Room Acoustics, Noise and Vibration Control, Acoustical Measurement, and other related fields.

10/2024: Welcome Dr. Zhou Tong (周桐) to my team as a postdoc fellow!

08/2024: Welcome Ma Kai (马凯) to my team as a visiting student!

08/2024: I was invited by the Hong Kong Institute of Acoustics (HKIOA) and the Australian Institute of Building (AIB) to give a talk on “Noise Reduction Enabling Natural Ventilation Technologies”.

Dr Liangfen DU joined the Department of Building Environment and Energy Engineering (BEEE) as an Assistant Professor in April 2024. She obtained her BEng in Environmental Engineering and MSc in Acoustics from the Northwestern Polytechnical University in China, and received her second Master’s degree and a PhD in Acoustics from the Institut National des Sciences Appliquées de Lyon (INSA Lyon) in France. After graduation, she worked as an Acoustic Consultant in the industry for various industrial projects involving noise impact assessment, acoustic design, building acoustics and more. She later returned to academia as a research fellow at the National University of Singapore (NUS) from 2017 to 2021 and at the Nanyang Technological University (NTU) in Singapore from 2021 to 2024, respectively. Dr Du’s research interests encompass noise reduction technologies enabling natural ventilation, acoustic metasurfaces, sound prediction, and environmental noise control.
