Dr Xiaohui Chen

Profile

I am an Associate Professor in Geotechnical Engineering at the University of Leeds with extensive cross-disciplinary research experience in geomechanics and geochemistry. My research focuses on Coupled Multiphysics Modelling and Physics-Informed Machine Intelligence, with broad industrial applications including geotechnical engineering, water research, subsurface disposal and energy, sustainable agriculture, and environmental engineering. I am also a Fellow of the Institution of Environmental Sciences and a Chartered Environmentalist (UK).

Geomodelling and Artificial Intelligence Group: I am the founder and director of the Geomodelling and AI Group, which comprises four postdoctoral researchers, 12 PhD students, and nine MSc/MEng students. The group has secured over £2.7 million in funding from research councils (including NERC, EPSRC, Horizon EU, and CSC) and industry partners. Our research focuses on cutting-edge theoretical, numerical, mathematical, and AI modelling in Geoengineering, with a proven impact in various industries such as petroleum, nuclear waste, carbon capture and storage, landfill, tunnelling, water, and agriculture. The group collaborates with world-renowned academics and institutions to achieve low-carbon, long-life geo-infrastructure, circular economy, and environmental protection, which mitigates the impact of climate change on human civilisation.

Research interests

Key Research Directions

  • Mixture Coupling Theory aims to develop a unified theory for multiphase flow transport in deformable porous media, with applications in various disciplines such as Geotechnics (e.g., nuclear waste disposal, CCS, borehole instability, etc.), Biogeotechnics (e.g. agricultural soils),  Medical and Bio Tissue Engineering (e.g., cancer research and tumour growth), and Chemical Engineering (e.g. steel erosion), among others. 
  • Coupled Multiphysics Modelling in Geotechnics and Environmental Engineering (Thermo-Hydro-Mechanical-Chemical-Bio) research focuses on filling the gap between subsurface geochemistry/geomicrobiology/hydrogeology/mineralogy and their effects on chemical transport. This research will lead to a deeper understanding of the influence of geochemical reactions and micro-organism activity on the transport of groundwater/heat/gas/air/radionuclide and the subsequent alteration of stress/strain underground. 
  • Physics-Informed Machine Learning (PIML) are a recent development in the field of machine learning. They combine the power of neural networks with the underlying physical laws governing a system. By incorporating physical laws as constraints during the training process, PIML can learn from limited and noisy data and predict the behavior of complex physical systems with high accuracy. This approach has shown great promise in various applications, including fluid dynamics, geomechanics, and materials science, among others. PIML represent a promising avenue for bridging the gap between data-driven machine learning and physics-based modelling, offering a more accurate and efficient means of modelling complex systems in the real world.
