Biography:

John joined the Geotechnical Research Group in October 2012 to conduct research on deep geomechanics with support from Engineering and Physcial Science Research Council (EPSRC) and Arup. He is a member of Churchill College.

He obtained his Bachelor degree from the University of Hong Kong in 2005. During his undergraduate study, he was a university representative in Inter-University Invitational Civil Engineering Competition among 7 top Asian universities and was awarded to Excellent Performance Award in Environment Engineering.

After graduation in 2005, John joined the Hong Kong Special Administration Region (HKSAR) Government as a Civil Engineering Graduate and was promoted to Assistant Civil Engineer in 2008, with a short period of training in Chongqing Municipal Construction Commission. In the meantime, he received a scholarship that partly funded his study in a part-time Master degree at Hong Kong University of Science and Technology.

In 2009, John switched his career to AECOM, the largest engineering consultant in Hong Kong, and specialized in the geotechnical field particular in underground construction. He obtained his chartership status and was admitted as a member of Institution of Civil Engineers (ICE) and Hong Kong Institution of Engineers (HKIE). Before he started his PhD study in Cambridge, he had been promoted to Project Engineer leading a small team of young engineers.

With 7 years spent in the industry, John has been involved in several mega scale underground railway projects in Hong Kong, including West Island Line, Grangzhou-Shenzhen-Hong Kong Express Rail Link and Shatin to Central Link. He was also involved in MRT Blue Line Extension in Bangkok and a cross-boundary highway tunnel in Liantang/ Heung Yuen Wai. He specializes mainly in soil structure interaction problems including deep excavation and soft ground tunneling by TBM or NATM methods in heavily built-up areas. Moreover, he has been involved in some specialized topics such as artificial ground freezing. He has also acquired some structural engineering experience and designed a 117m span cycle track bridge. Furthermore, he has more than 2 years of resident site experience including a mega site at Central Reclamation Phase III.

Research Interests

Deep Geomechanics

Enhanced geothermal system (EGS) is a low carbon energy technology that utilizes the heat source and capacity of the ground. A typical EGS utilizes subsurface holes of a depth from a few kilometers up to 10 km. Water is pumped down from some wells and superheated water or steam is extracted from the others. Fracturing the rock formation sufficiently is needed to enable a fluid to flow between the wells. The fluid flows along permeable pathways, picking up in situ heat, and exits the reservoir via production wells. The major issues of the current EGS are identification of a suitable site that can create a geothermal reservoir. The key assumption associated with reservoir creation is that sufficient volumes of rock can be stimulated with enough fracture surface area and permeability to enable the extraction of large quantities of heat. The efficiency depends on the geological condition that has been artificially fractured. The project will develop a “deep geomachanics” THM simulator coupled with micro-seismic geophysical analysis to examine the feasibility of EGS. It is proposed extend the analytical/numerical models of conventional deep geo-thermal wells to a generalized model for EGS and the newly developed model will be validated by laboratory model test data and field data.
