My career is connected with the Brno University of Technology, where I always liked to come back from my internships abroad. The electron-microscopy environment in Brno is extremely inspiring. At Brno University of Technology I teach courses related to physics of materials, nanotechnology, and I use electron microscopes intensively in my research activities in these areas. I enjoy uncovering the history of physical discoveries and explaining to students the circumstances of their origin in an entertaining and especially informative way.
