Giving his PhD dissertation talk he recapitulated his work on single-molecule microscopy and single-molecule tracking and showed us both, the biology of assembling1 and loading2 a bacterial needle complex, the injectisome, and also technical improvements for single-molecule microscopy using red-shifted marker beads3 and origamis (stay tuned, manuscript in prep.!).
It was also a great occasion, to celebrate our most recent publication2 from January this year, where we study the dynamic details of shuttling the effector proteins to the needle complex, finally in person with all first authors!
