Research interests focus on the general area of risk analysis, uncertainty modelling of Earth Systems Engineering. A cross-disciplinary endeavour aims to build an interface between the theoretical basic research, application oriented developments and numerical implementations. In the area of basic research, the focus is on the development of advanced stochastic computational methods for stochastic differential equation, reliability analysis and risk management. The developed procedures have been applied in different areas in civil engineering as well as in coastal engineering (embankment, dam, foundation). The numerical implementations have been resulted in the development of several software packages (such as GeoRiskR, and SADSS) for uncertainty quantification.

Who he is

Xingzheng was born in Liangshan County, ShanDong province of China (which is in the east of China between Beijing and Shanghai) in 1972. In 1990 he finished his high school at Liangshan No.1 high school. In the same year, he entered the ShanDong University of Technology (Now named ShanDong University) in Jinan. After four years, he received his B.S. in Civil Engineering in 1994 rewarded as top graduate, then pursued his M.S. degree in the same university on Solid Mechanics following a recommendation by the Academic Committee. The title of his master thesis is 'Study of Geosynthetic Reinforced Soil Embankment' [Abstract]. In 2001, he finished his Ph.D degree from the Dalian University of Technology, Dalian (a coastal city in Northeast). The title of his thesis is 'Constitutive Models of Coarse-grained Soils with Static and Dynamic Loading and Their Applications in High Concrete Faced-slab Rockfill Dam' [Abstract]. During his study, he worked as a research assistant for the National Science Foundation project of China and the 9th Five-Years Plan Project. In these projects, he was active on constitutive model and numerical approach in 3-D finite element analyses of a Rockfill Dam(CFRDSDB3).


At the beginning of 2001, he started working towards a new research field in the probabilistic optimization design and risk assessment of flood defences at China Institute of Water Resources and Hydropower Research (IWHR), (Research Center of flood and drought disaster reduction of Chinese Ministry of Water Resources in Beijing). The funding supported by the sub-theme of the WORLD BANK and the Youth Acceleration Fund of National Electric Power Corporation project, he and his colleagues developed the Software system for safety evaluation with multi-criteria on flood defences (SADSS, the description and evaluation version of the Software system [Introduction;Theory;UserManual]. In the meantime, he acted as a research secondment, funded by a cooperation programme between the Directorate-General Rijkswaterstaat (RWS) of the Ministry of Transport, Public Works and Water Management in the Netherlands (Delft), and his Research Center, stayed in Delft for three months. The comparison of the probabilistic modelling and their application on dike failure mechanisms for safety evaluation between the Netherlands and China was carried out [Report].


From July of 2004, he begins to pursue his international career as a postdoctoral research fellow at the University of Dundee. The 1st project involved by him is Physical and Mathematical Modelling of Soft Cliff Erosion and Coastal Erosion Risk Assessment, from the Leverhulme Trust. A process-based deterministic numerical model to predict coastal Cliff-Beach erosion due to wave actions was developed. The components (including slope stability, mass movement, beach erosion process) are ulitilised in a typical cliff-beach cross section and profile updating can be displayed on the screen in real time and some meaningful results were gained [Introduction].

The 2nd project at the University of Dundee, supported by EPSRC and cooperated with university of Plymouth, A Risk-based Framework for Predicting Long-term Beach Evolution. A newly long-term shoreline evolution model based on stochastic differential equation (SDE) was presented. The proposed model is able to account for the effects of uncertainties in breaking wave parameters and the initial shoreline position and provides an efficient means of predicting the complete stochastic characteristics of shoreline evolution without requiring a Monte Carlo sampling, validation against the historical and measured data at Christchurch Bay is completed [Introduction].


The 3rd project at the University of Dundee "New geotechnical approaches to soil biological processes", which was sponsored by UK Joint Research Council (MRC/EPSRC/BBSRC) Discipline Hopper scheme. The specific contribution of two-dimensional particle image velocimetry (PIV) to characterize penetration resistance of penetrometer, pressure meter deformation, root growth and earthworm burrow processes in compacted sandy and clayey soils was explored. Building linkage between geotechnical engineering installing and biological behaviour was attempted, it provides a basis for advancing the design of civil engineering in soils.


In June of 2009, he moved to the Newcastle University, UK. The 4th project who involved "Incorporating beach morphological changes to flood risk assessments attributed to climate change in a regional perspective" was sponsored by Tyndall Centre for Climate Change Research Phase II (Coastal). A direct Monte Carlo sampling method is developed to capture a wide range of inundation map and damages under all sorts of loading conditions, sea level rising, wave height and breached beach level, with overtopping and breaching failure mode.


The 5th project at the Newcastle University "A foresight future evolution implications of flood risk assessment by integrating near-shore beach morphological behaviour" was supported by an EPSRC Platform grant: Earth systems engineering: Systems engineering for sustainable adaptation to global change (Uncertainty analysis). Joint extremes of beach morphological changes are built to further analyze the potential expected annual damages in the impacted zone due to breaching events.

He always believes that he came into the world and will be ended up with in the research to handle with the uncertainty system in engineering by numerical models. It can be a miracle though hope is frail. During his research life, there might be pain, frustrations and loneliness, but after such experiences, hope and joy and happiness will emerge and long with the whole life.
