Biography
Dr. Zbigniew Sojka is the Professor of Chemistry in Jagiellonian University.He has been to the positions of Vice-Dean for Research and Cooperation; Head of the Inorganic Chemistry Department; Head of the Catalysis and Solid State Group; Head of the Faculty EPR Laboratory; Visiting Professor at the Universities of Paris and Lille. The research interest of his group focuses on molecular design, spectroscopiccharacterization and reactivity studies of nanostructured, porous and bulk inorganic materials functionalized with transition metal ions. The functionalization aims at imparting desired properties to the investigated materials and at guiding surface reactions along specifi c pathways. In our methodology we use computational spectroscopy and mole cular modeling for establishing quantitative structure-property-function relationships, and for working back from the observed kinetics to the underlying reaction mechanisms with quantum-atomistic resolution. Special emphasis is put on the elucidation of the electronic and magnetic structure of active sites and intermediates, and on the development and application of advanced EPR methods for in situ investigation of heterogeneous materials.
