Thesis title: Human behaviour in High-Risk Environments: Understanding how role setting influences individual assertiveness and decision-making in dyads and small teams

Supervisors: Professor Peter Ayton and Professor Lorenzo Strigini

Higher educational background

  • MSc Air Safety Management

Overview and research interests

Tom looks for reasons behind the recurring phenomena of missing or ineffective intervention and undesired human decision-making in high-risk-environments despite already implemented human factor trainings. His work deals with the work-reality of dyads and small teams in High-Risk-Environments with a special focus on advantages and disadvantages of traditional team and role settings versus alternative options for effective accident and incident prevention.
