Biography

PhD (HK PolyU)

 

Short Description

 
Dr. Tuo Liu received his BSc degree in Acoustics from Nanjing University in 2010 and MSc degree in Physics from China University of Petroleum (Beijing) in 2013. After graduation, he had worked as an acoustic engineer in industry for about 1 year. In 2018, he obtained his PhD degree in the Department of Mechanical Engineering, The Hong Kong Polytechnic University. Before being appointed as Research Assistant Professor, he was first a research associate and then a postdoctoral fellow in the same department.

Dr. Liu’s research interests focus on physical acoustics, acoustic metamaterials, non-Hermitian acoustics and other acoustics-related topics. His work has been published in top-tier journals including Physical Review Letters and Nature Physics. He is a member of the Acoustical Society of America and the Acoustical Society of China. He also serves as a reviewer for a number of journals in the field of physics and acoustics.
