Recent Research Projects

My wind energy research is mainly funded by national agencies such as the National Science Foundation project I lead entitled, "Multiple wake interactions in large wind farms" that incorporates modeling, measurements and analysis of data from large wind farms.

I am also focusing on quantifying offshore wind resources and wind turbine wakes in projects funded by the Department of Energy in a project I am leading entitled, "An integrated approach to offshore wind energy assessment: Great Lakes 3D Wind Experiment" that uses remote sensing and traditional measurements, and in a project led by the National Laboratory for Renewable Energy to develop better models for predicting power and loads in offshore wind farms entitled, "Simulator for Offshore Wind Plant Applications", and in a project led by the Danish Technical University Risoe Wind Energy Department that is funded by the European Commission entitled, "Design Tools for Offshore Wind Farm Cluster (Offshore Cluster)."

I also work with private companies to improve their wind resource and wind power estimates using both measurements and modeling.
