Short CV
Dr. Dumisani Kama completed his M.Sc. in 2015 working on phosphorus bidentate ligands coordination to various platinum group metals and their application thereof to various homogeneous catalytic systems. He obtained his Ph.D in Inorganic chemistry in 2018 at the University of the Free State under the supervision of Prof A Roodt and Prof A Brink. His Ph.D research was on structural and reactivity relationships aryl- and alkylamine bisphosphine complexes of Tc-99 and Re(I).
