Job: Postdoctoral researcher and X-ray crystallography support to the Center for Catalysis and Peptide Research Unit, UKZN, South Africa.Duties: Crystallization, Crystal growth of novel inhibitors, Chiral seperation by host-guest chemistry, and Protein crystallization. Teaching crystallography, crystallization techniques, crystal structure solution to the students and writing crystallography papers for the group.

Job: Postdoctoral research on Inclusion Compounds and Host-Guest Chemistry for chemical separations.The work is carried out and characterized by 1H and 13C NMR, Thermal Gravimetric Analysis (TGA) and Differential Scanning Calorimetric (DSC) to study the different guest proportions and phase transitions in the crystals. The structure of the host-guest systems were characterized by single crystal X-ray diffraction technique. Hot stage optical microscope analysis for phase transition of the single crystals and solid samples. I have also gained experience in solid state kinetics of decomposition and enclathration of Inclusion compounds.Adviser: Professor Luigi R Nassimbeni
