Jonathan Weidow

Docent at Chalmers, Physics

I have the assignment as director of undergraduate studies at the Departments of Physics at Chalmers and at the University of Gothenburg (GU). My main task with this assignment is staffing planning with the overall goal of generating the best possible teaching.In my research, I investigate the microstructure of different materials and connect this to the material properties.The courses I am responsible for are the Tools of Engineering Physics, the first course in the Master of Science in Engineering Physics program, and for the eight courses in school-based education in physics and technology for the teaching education program at the University of Gothenburg. I am also program responsible for the teaching education program in technology (GU).
