I earned my Ph. D. (with Prof. James Grimshaw on Electroactive Polymer modified Electrodes with poly(amino acids), polypyrroles, and polythiophenes) in 1989 from the Queen’s University of Belfast, UK. From September 1989 to May 1995, I was a Research Fellow at the University of Leeds where I carried out research work in the areas of Organometallic ChemistryCatalysis (with Prof. Bernard L. Shaw, FRScomplexes of PO, PN, PP, PNP, PNN, PNS, PNO, PNC, NNC ligands, cyclometallation, agostic interaction, F coordination, CH and CX bond activation and Heck olefination) and Boron Chemistry (with Prof. John D. Kennedycomplexes of B16H20, B18H22, and B20H16 andthiaboranes).

I joined The Open University of Sri Lanka as a Senior Lecturer in Chemistry (1995-2003), was appointed Head/Department of Chemistry (April 2002 to September 2004). I was promoted to Professor in Chemistry (2003-2011) and then to Senior Professor in Chemistry (November 2011 to date). I have authored about 20 Chemistry Books. I involved in publishing over 70 Scientific Papers in International refereed Journals with over 1000 citations and I have presented about 50 papers in Conferences. I am a recipient of many Research Fellowships from University of Leeds (1989-2002) and Trinity College Dublin, Ireland (2005 to 2018, with Prof. Sylvia M. DraperN- and S-dopedgraphenes, complexes of N-heterosuperbenzene, azafluoranthenes and pyridyl polyphenylenes, and inorganic polymers). I have received many Research Awards including CVCD Excellence Award in 2012 for the Most Outstanding Senior Researcher in Physical Sciences. I was the Editor-in-Chief of the OUSL Journal of The Open University of Sri Lanka for 3 years (2014-2016).
