I am a Reader at Imperial College London, working on the application of AI and Machine Learning to Earth and planetary systems. My work invludes applied AI for satellite imagery, as well as computer vision for geological images, notably carbonate systems. I also run a stable isotope lab capable of doing clumped isotopes on carbonates.

My main interests include:

  • Application of neural networks and machine learning for geological applications, for instance, image recognition to automatically extract information from core and thin sections.
  • Clumped isotope geochemistry for carbonate paleo-thermometry, notably in the context of carbonate diagenesis
  • Numerical methods and programming, such as forward modelling of stratigraphy or development of software for geochemistry

The information presented here is just a brief summary. If you are interested in more information, for instance if you want to work with me, visit the my carbonate research group website:

Research Interests

  • Use of machine learning, notably neural network, for automatic feature extraction from unstructured geological data (for instance, image recognition of facies in cores)
  • Forward modeling of sedimentary processes to constrain the architecture of carbonate systems and the distribution of different facies 
  • Clumped isotope geochemistry and thermal history of carbonate, notably applied to carbonate diagenesis
  • Continental margin sediment and shallow-water carbonates. notably linked to field research
  • Climate change and the environment
