2 x Project Data Scientists (2025 - 2025)
Affiliation : University of Exeter & Met Office, UK
Topic : Bayesian Machine Learning Framework for Probabilistic Impact-Based Hazard Decision-Making
Supervisors : Jawad Fayaz, Steven Ramsdale (Met Office), and Andrew Howes (UoE)

Two postgraduate Data Scientists worked on the development of a probabilistic simulation environment of vulnerability parameters for training reinforcement-learning-based impact-based decision-making agents for natural hazards. The project explicitly integrated physical susceptibility, socioeconomic vulnerability, community preparedness, and recovery capacity, using Bayesian hierarchical modelling to address uncertainties and enhance decision-making realism. This approach aimed to produce a robust and evidence-based framework that improves proactive risk management and emergency response capabilities.

Topic : Digital Twinning for Transport Management
Supervisors : Farzad Rahimian (TU), Annalisa Occhipinti (TU), and Jawad Fayaz

Zainab worked as a KTP Associate with Teesside University & Nicander Ltd on intelligent digital twins for transport infrastructure management. Her research focused on applying data science and AI to intelligent transport systems. The partnership connected academic research with transport software development, alongside Nicander's work on asset and fault management and bus-priority solutions.

Dr. Lauren McMillan
Dr. Lauren McMillan
PhD Student (2021 - 2024)
Affiliation : University College London, UK
Topic : Artificial Intelligence-Based Decision Support for Water Distribution Systems’ Health Monitoring
Currently : Lecturer at Northumbria University, UK
Supervisors : Liz Varga (UCL) and Jawad Fayaz

Lauren completed her PhD in Civil, Environmental, and Geomatic Engineering at University College London (UCL), UK. Her research focused on enhancing the resilience and sustainability of critical infrastructure systems through systems-based, data-driven methods. She developed intelligent, data-driven solutions for each phase of leakage management—anticipation, detection, and restoration—envisioning a self-healing system. These solutions were trained and tested on a dataset of over 2,000 district-metered areas managed by a UK water company. This approach provides a rapid and cost-effective method for identifying potential leaks, offering benefits such as increased infrastructure resilience, optimized repair strategies, and improved consumer confidence, which together promote sustainable demand-side behaviours.
