Dimitrios Gournis is a Professor of Nanomaterials and Nanotechnology in the School of Chemical and Environmental Engineering at the Technical University of Crete (TUC), Chania, Greece. He is an experimental synthetic chemist working in the area of layered and nanoporous materials. Since 2023 is affiliated faculty (and vice-director since 2024) of Institute of GeoEnergy, and member (and vice-director) of Physical Chemistry & Chemical Processes (PCCP laboratory) of School of Chemical and Environmental Engineering of TUC (www.pccplab.tuc.gr).

His research interests are focused on the synthesis, characterization and study of the properties of layered (2D) materials [in particular inorganic layered structures, clay-based materials (clays, pillared clays, organo-clays, LDHs), carbon layered structures, TMDs, germanane, silicane, MXenes etc], carbon nanostructures (carbon nanotubes, fullerenes, graphenes, carbon dots, molecular diamonds), hybrid organic–inorganic nanocomposites, metallic (magnetic, catalytic or semiconducting) nanoparticles, mesoporous materials (carbon or silica-based) and biocatalysts.
