Hajo Spaethe, applicable BSc. Wood Science University of Hamburg and University of Freiburg, Germany

Masters Student Forestry
University of Alberta (Canada) & University of Freiburg (Germany)

In my undergrad, I studied wood science at the University of Hamburg, Germany which is not directly connected to preservation but it gave me a solid understanding of the working material - wood. In my Master's, I switched to forestry (conservation) at the Albert-Ludwigs University in Freiburg. As part of the Transfor-M program (an exchange program between European and Canadian universities), I studied my second year at the University of Alberta finishing with my thesis project (course-based Master): "Preliminary Evaluation of Coatings for Preservation of Historical Wood Structures in Alberta". The results will be presented at the APT Buffalo Niagara 2018.
