Biography
Dr Cheng-Yu Hong (洪成雨) is currently an associate professor in Department of Civil Engineering of Shantou University. He received a BSc and an MSc in mainland China and a PhD from The Hong Kong Polytechnic University in Oct 2011. After worked as a research associate in The Hong Kong Polytechnic University for one year, Dr Hong joined Shantou University in 2012. Currently Dr Hong has published 10 international journal papers and 13 conference papers. He also served as reviewers for two international journals: ASCE International journal of Geomechanics and ICE Geoenvironmental Geotechnics. His research concerns involve pullout resistance of pressure grouted soil nails; long-term monitoring of conventional soil nails and GFRP bar soil nails, and application of different optical fiber sensor technologies (fiber Bragg grating sensor; Low Coherence Interferometry; Brillouin Optical Time Domain Analysis) in geotechnical engineering projects.
