Short CV

Elizabeth (Lizette) Erasmus completed her M.Sc. in 2003 at the University of the Free State, working on titanium beta-diketonato complexes for medical applications. She obtained her Ph.D. in 2006 from the same university where she worked on ruthenoceneyl-containing beta-diketonato titanium complexes, with the focus being on their electrochemical properties and some kinetic aspects.

She is a Senior lecturer in the Department of Chemistry at the University of the Free State. Her main research focus is surface chemistry and heterogeneous catalysis. Lizette has worked as a Senior Researcher at the CSIR before joining the Physical chemistry group at the University of the Free State in 2009. Since then she has made a number of international research visits to the labs of Prof Hans Niemantsverdriet at the Technical University of Eindhoven in the Netherlands and Prof Bruce Gates at the University of California Davis in the United State of America.

Dr. Erasmus’s research mainly focuses on bimetallic heterogeneous catalyst prepared from single source heteronuclear organometallic compounds.
