I have received my masters degree from KTH, stockholm and studied sustainable energy engineering with specialisation on wind energy. I worked within wind resource assessment area during my master thesis at AQSystems, Göteberg and an internship at Fraunhofer institute, Kassel.

My current research primarily focussed on detection and classification of icing events on a wind turbine blades. During the time, I have also been started working with classification and characterisation of snow/ice for road, ski pits applications. The objectives of my study were investigated based on multispectral imaging, where intensity refelcted from snow surfaces was investigated. This is performed as different phases of water exhibits distinct absorption properties at a given wavelength of light as one can see in the below picture. 


Short description

  • Detection and classification of icing events for wind turbine applications
  • Classification and characterisation of snow for winter road maintanace and skis preparation
  • Multispectral imaging, where wavelegnths from infrared regions are considered and an infrared camera to image the intensity refelcted. 
  • Correlation between physical properties of snow/ice and multispectral imaging is investigated.
