Dr. Johan Casselgren is an Associate Professor in Experimental Mechanics at Luleå University of Technology (LTU), specializing in the study of snow and ice. With over 18 years at LTU, he has developed innovative solutions to challenges posed by cold climates. Notably, he created a system that combines camera technology, artificial intelligence, and weather data to detect and predict ice formation on wind turbine blades, enhancing their efficiency during winter months. Dr. Casselgren’s research extends to various applications, including the development of a portable bevameter for measuring snow properties in the field, aiding in vehicle and tire testing on snow-covered tracks. He also contributed to the discovery of the “snabel snöflingan,” a unique snow crystal, using advanced imaging techniques. In recognition of his contributions, Dr. Casselgren was named Innovator of the Year 2023 at LTU. Beyond his professional endeavors, he is passionate about outdoor activities, particularly skiing, which aligns with his research interests and provides practical insights into the dynamics of snow and ice.
