ImpactWind SouthWest (2022–2027): Facilitating sustainable offshore wind development in Norway through interdisciplinary research, open-access data, and educational initiatives. The project aims to improve regulatory processes and strengthen collaboration between academia, industry, and public authorities.

LOWT (2022–2027): Large Offshore Wind Turbines – Structural Design Accounting for Non-Neutral Wind Conditions. The project investigates the influence of atmospheric stability on turbulence, wind turbine loads, and wake dynamics. It combines offshore wind measurements, remote sensing, and numerical modelling to improve the design of large offshore wind turbines.

COTUR II (2021–2022): Analysis of the COTUR measurement database to improve the characterisation of offshore atmospheric turbulence and spatial coherence. The project focused on evaluating turbulence models and extracting information from synchronised Doppler wind lidar measurements.

COTUR (2018–2020): Measuring Coherence and Turbulence with Lidars. The project investigated the spatial coherence of atmospheric turbulence over the sea using synchronised long-range Doppler wind lidars. The measurement campaign provided a unique dataset for improving offshore wind turbulence models and wind turbine load calculations.
