About Me

I am a Postdoctoral Researcher at NTNU’s Department of Structural Engineering, specialising in vehicle aerodynamics and crosswind risks for road vehicles. My research focuses on developing data-driven methodologies to assess aerodynamic loads and improve transport safety in challenging wind conditions. By integrating sensor-based force estimation, vehicle dynamics modelling, and full-scale field testing, I aim to enhance the understanding of wind-induced vehicle instabilities and contribute to safer, more resilient road transport systems.

Research Interests

Aerodynamic Force Estimation: Developing observer-based methods to estimate wind loads on vehicles using onboard sensor data.
Driver Modelling & Human-in-the-Loop Dynamics: Investigating how drivers perceive and respond to crosswind disturbances, and developing control-based models that capture driver compensation strategies in time and frequency domains.
Crosswind Risk Assessment: Investigating how strong winds affect vehicle stability and accident likelihood.
Full-Scale Testing & Field Experiments: Conducting real-world vehicle tests to validate aerodynamic models and risk assessment methods.
Data-Driven Transport Safety: Leveraging vehicle sensor data, statistical wind modelling, and machine learning to improve road safety.
Structural & Vehicle Dynamics: Studying the interaction between aerodynamic loads, vehicle response, and driver behaviour.
