Experimental, theoretical and computational molecular optics. Measuring and modelling intermolecular interaction effects.
My main research interest lies in measuring the molecular electric quadrupole moment of various gases using the technique of electric-field-gradient induced birefringence. We have succeeded in measuring the quadrupole moments of nitrous oxide, carbon dioxide, carbon monoxide, hydrogen and carbonyl sulphide. These results are highly sought after by the molecular physics community. Currently we are the only resaearch group in the world with a working set of apparatus to perform such measurements.
I also have a keen interest in Physics educationa and a current research project is a feasibility study on teaching Physics in isiZulu.
