Welcome to the Theoretical Chemistry Group

We aim to understand excited state processes in condensed phases and complex environments and to develop new methods that enable us to do so accurately.

1. Physical Chemistry: Our work is motivated towards understanding light-matter interaction.

2. Theory and Computational Science:  We develop and apply accurate quantum chemical methods to understand the interaction between light and coupled bio-chromophores. Electronic structure theory gives us unique tools to understand the energy states of the chromophores and their coupling to each other and therefore, gives us a glimpse into their photochemistry and photo-dynamics.

3. Developmental Works: We develop new methods to enable us to understand photo-processes. Our codes are part of Quantum Chemistry Software Q-Chem. Students with a sound knowledge of coding has opportunity to excel in this field.
