Faculty Profile

Guoxiang Liu received the B.Eng. degree in surveying engineering from the East China Institute of Geology in China in 1991, the M.Eng. degree in geomatics from the Southwest Jiaotong University in China in 1994, and the Ph.D. degree in remote sensing from The Hong Kong Polytechnic University in China in 2003.

Dr. Liu is currently a Professor with the Department of Surveying and Geo-Informatics  at the Southwest Jiaotong University (SWJTU), Chengdu, China, and the Dean of the Faculty of Geosciences and Environmental Engineering of SWJTU. From 2010 to 2012, he was the Associate Dean of the School of Civil Engineering of SWJTU, and the Executive Dean of the Faculty of Geosciences and Environmental Engineering of SWJTU. From 2013 to 2016, he was the Executive Dean of the Graduate School of SWJTU. From September of 2005 to September of 2006, he was a Visiting Scholar and conducted collaborative research with Dr. Sean M. Buckley in the Department of Aerospace Engineering and Engineering Mechanics at The University of Texas at Austin. From September to December of 2008, he worked as a Research Fellow and conducted collaborative research with Prof. Xiaoli Ding in the Department of Land Surveying and Geo-Informatics at The Hong Kong Polytechnic University.

In recent years, Dr. Liu has been actively involved in the development of advanced radar interferometry techniques such as persistent scatterer radar interferometry and the relevant software package development as the principal investigators for several research projects granted by the national-, provincial- and ministerial-level research funds (e.g., the National Natural Science Foundation). These new processing approaches have been used to detect and inverse subsidence caused by groundwater withdrawal in urban areas and along linear structures, as well as ground deformation related to volcano, landslide and earthquakes.
