We were pleased to host Prof. Dr. Ben Engel from the Biozentrum in Basel for a guest seminar at the RPTU on Monday, January 16, 2023. The seminar was organized in cooperation of STRESSistance and the Biological Colloquium of the Faculty of Biology. We thank Ben for his great and inspiring talk on the exploration of the molecular architecture of photosynthetic organelles with cryo-electron tomography and for spending time with our PhD students for a discussion on scientific and career-related topics during a casual pre-talk meeting.
