Panagiotis L. Kastritis studied Biology at the University of Athens (Greece) and specialized in Structural Biology. In 2012, he earned his Ph.D. in Chemistry in the NMR Spectroscopy group at Utrecht University (The Netherlands). From 2013 to 2018, Panagiotis Kastritis was a postdoctoral researcher at the EMBL Heidelberg (Germany), where he characterized cell extract structures with integrative modeling methods. In 2018, he started his own research group within the ZIK HaloMem program and was appointed as Junior Professor for “Cryo-Electron Microscopy of Membrane Protein Complexes” at the Martin Luther University of Halle-Wittenberg (Germany). Since 2023 he is also the ERA Chair for cryo-EM at the Hellenic Research Foundation in Athens, Greece, where he leads his second laboratory to establish the cryo-EM in south east Europe. Panagiotis Kastritis aims to understand cellular architecture via the analysis of native cell extracts. His main interest is on using cryo-EM as a core biophysical method, together with computational structural biology and XL-MS, for a structure-based modeling of biomolecular interactions.
