John Wheeler

Professor John Wheeler is a faculty member at the University of Liverpool's School of Environmental Sciences, Department of Earth, Ocean and Ecological Sciences. His work bridges geological processes with materials science through the lens of stress-chemical interactions in crystalline materials.

Research interests span three primary themes:

• Development of Electron Backscatter Diffraction (EBSD) techniques for crystal orientation analysis
• Fundamental links between stress and chemical processes in geological systems
• 4D visualization of metamorphic dehydration reactions using synchrotron tomography

Key methodologies include diffusion creep modeling, dislocation density analysis, and solid-state phase transformation studies across rocks, metals, and ceramics.

His publications reveal a focus on magma emplacement dynamics, mantle convection feedback, and deformation mechanisms in minerals. Research grants from the Natural Environment Research Council (NERC) support projects like 'Feedbacks between mineral reactions and mantle convection' (2022-2028) and '4D micro-scale quantification of coupled mineral dehydration' (2020-2022).

Professional activities highlight extensive involvement in academic conferences, including co-convenor roles at international geoscience meetings and editorial contributions to Earth Systems reference works. Teaching responsibilities include coordinating modules on crust-mantle dynamics, metamorphism, and research methods.
