The electronic excitiation of a molecule or a nanoparticle is the primary initial event in several schemes associated with the control of molecular machines and several new photopharmacological and photoinitiation schemes. Understanding the excited state dynamics of chemical compounds is to understand the nature of its behaviour and its properties. The range of our research includes everything from nitroaromatic compounds and their importance to enviornmental chemistry to the ultrafast excited state dynamics of DNA.

Exploiting a molecules linear and non-linear optical properties brings exciting opportunities in their applications.
