Dr. Edward Rajaseelan

Research Interests

Dr. Rajaseelan's research interests are in the areas of synthetic inorganic, bio-inorganic, and organometallic chemistry. His research involves synthesis, characterization of transition metal complexes consisting of nitrogen oxides, N-heterocyclic carbenes, and chelating phosphines as ligands. These complexes have many potential uses as catalysts in green chemistry, organic synthesis, and in various industrial reactions.

About Dr. Edward Rajaseelan

Dr. Rajaseelan joined the Chemistry Department in August of 1990, following a year of teaching and research at St. Olaf College, Northfield, MN. He did his sabbatical research at Brown University, Providence, RI in 1997 on organometallic catalysts for industrially important hydrodesulfurization reactions, and at Yale University, New Haven, CT in 2005 on N- Heterocyclic Carbene Complexes, a new generation of catalysts in organic synthesis.
