Biography
Dr Derek G. Ma is an Assistant Professor at the University of Warwick. His research sits at the interface of applied mathematics, AI, stochastic modelling, uncertainty quantification, and risk analytics. His current programme connects three complementary research branches:
- AI-informed random fields and risk assessment – learning spatial uncertainty while preserving mathematical structure;
- Visual AI for geomaterials – translating images and physical evidence into interpretable models of material behaviour;
- Energy risk pricing and decision-making – turning uncertain evidence into robust, risk-aware decisions.
Across these branches, he develops data-driven and physics-informed methods for complex physical, environmental, and financial systems, with applications across geosystems, natural hazards, energy, and finance. This interdisciplinary work has been recognised through a prestigious Early Career Fellowship.
He was awarded Global Talent status by the Royal Academy of Engineering and contributed to policy advisory work with the Welsh Government’s Coal Tips Safety Taskforces before taking up his permanent academic position at the University of Warwick. He also serves as a corresponding member of ISSMGE TC309, the technical committee on Machine Learning and Big Data.
His broader academic mission is to turn uncertainty into actionable risk intelligence. Further details are available on the Personal Website.

Research Interests
From uncertainty to informed decisions. A silent, 10-second conceptual animation using synthetic data; not a model output or scientific result. The animation plays silently; use the player controls to pause, or view the static illustration.
Animation description
A synthetic random field represents spatial uncertainty, with five points indicating sparse observations. An estimated curve retains an illustrative, non-zero uncertainty band. Two generic loss distributions, distinguished by dashed and solid lines, show how decisions can compare performance and tail risk. The arrows describe a research workflow, not a validated computational pipeline. The uncertainty is not calibrated, and neither option is claimed to be optimal.
Derek works at the interface of applied mathematics, artificial intelligence, stochastic modelling, and decision science. His research asks how incomplete, heterogeneous, and spatially varying evidence can be converted into reliable, risk-aware engineering decisions.
AI-informed stochastic fields and uncertainty quantification
Random fields, Bayesian inverse methods, probabilistic modelling, and physics-informed machine learning for characterising spatial variability and propagating uncertainty through complex engineering systems.
Visual intelligence for engineering materials
Computer vision, image segmentation, and perception-based modelling to extract interpretable material features and connect visual evidence with physical behaviour.
Computational risk and decision analytics
Reliability analysis, catastrophe risk, risk pricing, and robust decision-making for natural hazards, energy, infrastructure, and emerging financial systems.
Methods: stochastic processes; random fields; Bayesian inference; uncertainty quantification; machine learning; computer vision; and numerical modelling.
Teaching Interests
Derek teaches and supervises across engineering mathematics, mathematical modelling, project-based learning, and degree apprenticeship education. His teaching helps students move from formulas to model-based reasoning, connect mathematical structure with engineering practice, and use analytical and computational methods with confidence.
