Gu was born in 1960 in the outskirts of Shanghai, China, to parents who were both primary school teachers. He entered school in 1966, the year that the Cultural Revolution began. His education was severely disrupted in the chaotic period, and he "graduated" from high school after only nine and half years, with just two and half years of uninterrupted schooling. He was working as a farmer in rural Shanghai when the National College Entrance Examination was resumed in late 1977, a year after the end of the Cultural Revolution. He took the exam and was admitted to the Department of Applied Physics of Shanghai Jiao Tong University. After earning his B.S. in 1982, he pursued graduate studies at the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences, obtaining an M.S. in 1984 and a Ph.D. in 1988. He moved to Australia in 1988, initially as a visiting scholar.
Career
Gu was a Laureate Fellow of the Australian Research Council and a University Distinguished Professor in optoelectronics and Foundation Director of the Centre of Micro-Photonics at Swinburne University of Technology. He was appointed as Pro Vice-Chancellor for International Research Collaboration, Research Innovation, and Research Capacity at Swinburne. He was also the Foundation Director of the Victoria-Suntech Advanced Solar Facility from 2010-2015. From 2003-2015 he was a Node Director of the Australian Research Council Centre of Excellence for Ultrahigh-bandwidth Devices for Optical Systems. From 2005 - 2010, he was a node leader of the Australian Cooperative Research Centre for Polymers. Previously, he was the Special Advisor to Swinburne’s Vice-Chancellor, Acting Deputy Vice-Chancellor and Vice President, Dean of Science, Acting Dean and Deputy Dean of Engineering and a member of the University Council, Academic Board, and Board of Research. Gu is an authority in the fields of nanophotonics, nanofabrication, biophotonics and multi-dimensional optical data storage with internationally renowned expertise in three-dimensional optical imaging theory. He is the sole author of two standard reference books, Principles of Three-Dimensional Imaging in Confocal Microscopes, and Advanced Optical Imaging Theory. He is also the first author of Femtosecond Biophotonics: Core Techniques and Applications,. and Microscopic Imaging through Tissue-like Media: Monte Carlo Modelling and Applications .
