Research Statement
Our research is directed toward understanding the nature of the interaction of molecules with light – the field known as molecular photonics. Of special interest are molecules containing multiple chromophores, including DNA and organic molecules with arrays of stacked aromatic chromophores. The principle activity of our group is the design and synthesis of molecules expected to have specific photonic behavior.
