Dr. Nick Barua Research Overview


πŸ”¬ Research Profile

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:

πŸš— Safety-Critical Mobility and Injury Prevention

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.

πŸ”‹ EV Battery Intelligence and Trustworthy Machine Learning

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.

🌐 Broader Research Background

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.

1. Battery State-of-Health as a Functional Safety Variable

Scientific Reports Open Access

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.

3. Multimodal AI for Non-Upright Pedestrian Detection

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.
