My current research work centers on the development and deployment of novel biophotonic technologies that interface and bridge Physical Chemistry, clinical diagnosis, and Raman imaging. Specifically, I seek to employ vibrational spectroscopic and imaging techniques to obtain biochemical signatures that can reveal latent information on pathological conditions.
My doctoral work was focused on unraveling the spectroscopic mystery displayed by a biologically important molecule called thioxanthone by providing both structural and dynamical insights in its triplet excited state responsible for unusual but important photochemical and photophysical properties. We investigated the triplet state structure of the thioxanthone and recorded the first-ever Raman spectrum of this important molecule in its triplet-excited state. Structural information derived from this study has significantly helped to better understand the triplet state photochemistry of the thioxanthone. We for the first time probed two triplet states simultaneously using time-resolved resonance Raman spectroscopy.
