Senior Professor in Chemistry

Department of Chemistry

I earned my B. Sc. (Special) Degree in Chemistry with a Second Class Upper in 1982 from the University of Sri Jayewardenepura. I received my Ph. D. (with Prof. James Grimshaw on “Electroactive Polymer modified Electrodes”using 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 Chemistry, Catalysis (with Prof. Bernard L. Shaw, FRS – complexes of PO, PN, PP, PNP, PNN, PNS, PNO, PNC, NNC ligands, cyclometalation, agostic interaction, F coordination, CH and CX bond activation and Heck olefination) and Boron Chemistry (with Prof. John D. Kennedy – complexes of B₁₆H₂₀, B₁₈H₂₂, and B₂₀H₁₆ and thiaboranes).

Then, 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 over 20 Chemistry Books. I am involved in publishing over 75 Scientific Papers in International refereed Journals with over 1200 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. Draper – N- and S-doped graphenes, 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).
