Research Interests 
Organometallic polymers. Formation and evaluation of silyltransition mixed valence polymers with potential as sensors and conducting polymers.

Self-assembly in organotin biocides. Both intra-and inter-molecularly self-assembled organotin compounds are designed to impact their biological selectivity.


Actinide extractants. The modification of traditional CMPO ligands to facilitate, inter alia membrane separation is in active progress.
