My research sits at the intersection of safety-critical artificial intelligence, physics-based modelling, sensing, biomechanics, and functional safety.
Two connected research streams currently define much of my work:
I investigate how vehicle safety systems can better detect, interpret, and respond to difficult or atypical safety scenarios, particularly non-upright pedestrians and vulnerable occupants.
This programme connects:
- multimodal sensing and sensor fusion;
- computer vision and uncertainty-aware AI;
- forensic biomechanics;
- pedestrian-impact reconstruction;
- injury-risk modelling;
- autonomous vehicle and ADAS safety; and
- ISO 26262-aligned functional-safety architectures.
The broader objective is to move from post-event forensic reconstruction toward proactive detection, intervention, and injury prevention.
A second major research stream examines battery State-of-Health (SoH) from both machine-learning and functional-safety perspectives.
My recent work investigates:
- battery SoH estimation;
- validation inflation and model generalisation;
- cross-cell transfer reliability;
- predictor structure;
- battery-health uncertainty;
- EV power-margin integrity; and
- the role of battery condition in safety-critical vehicle functions.
The central question is not only whether a model performs accurately on familiar data, but whether its predictions remain reliable when transferred to previously unseen cells and real operating conditions.
Research principle: High apparent accuracy is not enough for a safety-critical system. The system must remain reliable when the operating conditions, data distribution, or physical system changes.
Earlier and parallel research includes geospatial intelligence, remote sensing, satellite-data analysis, computational astrophysics, stellar-population modelling, and galactic evolution.

Predictor Structure Modulates Validation Inflation and Cell-Transfer Reliability in Battery State-of-Health Estimation
This study examines an important limitation in machine-learning-based battery SoH estimation: strong validation performance does not necessarily imply reliable generalisation to an unseen battery cell.
The work investigates how predictor structure, validation strategy, and cell-to-cell transfer influence apparent model performance and cross-cell reliability.
A central implication is that battery-health models should be judged not only by their accuracy on familiar data, but also by their ability to transfer reliably to previously unseen cells.

Battery State-of-Health as a Functional Safety Variable: an ISO 26262-Aligned AI Framework for Electric Vehicle ADAS Power Integrity
This research treats battery State-of-Health as a functional-safety variable, rather than solely as a maintenance indicator.
It presents a five-layer architecture linking:
SoH estimation β power-margin monitoring β safety decision logic β vehicle response β lifecycle management
The framework examines how battery degradation and auxiliary electrical demand may affect the power margin available to safety-critical ADAS functions.

A Multi-Modal AI System for Detecting Pedestrians Lying on the Road: Simulation-Based Safety and Injury Risk Analysis
This research investigates one of the difficult edge cases in automated vehicle safety: detecting pedestrians who are already lying on the road.
The work combines multimodal sensing, AI-based detection, simulation, and injury-risk analysis to examine how improved perception could support earlier intervention.
