Research Interests

His research focuses on multivariate modelling/AI prediction/probabilistic analysis in earth sciences, specifically for failure analysis and risk assessment of granular flows, avalanches, and natural hazards. Derek develops robust statistical numerical algorithms through the integration of Computational Statistics and Data Science to quantitatively evaluate the uncertainties of granular flows in heterogeneous materials that exhibit significant randomness.

Research portfolio includes:

• Stochastic Analysis of Geo-systems (e.g. Random Field, Bayesian Inference)
• Risk Assessment and Crisis Response of Natural/Anthropological Disasters
• Artificial Intelligence and Machine Learning (e.g. Deep Learning)
• Risk Pricing for catastrophe insuranceLink opens in a new window and catastrophe bondsLink opens in a new window.
