Dmitry A. Semchonok is a Principal Investigator at ITQB NOVA, leading the Cryo-EM Integrative Structural Biology Laboratory. His research employs cryo-electron microscopy to investigate multisubunit protein complexes in photosynthetic organisms and cellular transport mechanisms involving COPI and COPII vesicle structures. As a workshop instructor for Grid Preparation for cryoTEM, Dmitry provides hands-on training in grid preparation and sample vitrification techniques essential for cryo-transmission electron microscopy.
