Personal profile（个人简介）

Dr. Bilong   Liu is now a professor and the director of Acoustic & Intelligent Control   Laboratory at the School of Mechanical and Automotive Engineering, Qingdao   University of Technology, China. He has more than 20 years of experience on   vibro-acoustic research after he completed a B.S. degree in physics. He   received a PhD in acoustics at the Institute of Acoustics, Chinese Academy of   Sciences (CAS) in 2002. Then he worked on noise transmission of aircraft   plates at MWL, KTH, Sweden, and received another PhD in applied acoustics   from KTH in 2006. From 2007-2017, he had been working as a research professor   and leading the group on acoustical materials and structures at the Institute   of Acoustics, CAS. Dr. Liu has competed over 30 projects for industries and the   government, has authored and co-authored over 100 journal papers, conference   articles, and three-volume monograph of “Vibro-Acoustics”. He was honored as   “Distinguished Research Professor of CAS” at 2015 and was invited to give a distinguished   plenary lecture on “Noise transmission and absorption of lightweight   structures” at ICSV26, Montreal.
