Our research interests are broadly in the direction of addressing the excited-state reaction dynamics that are mediated by fundamental processes such as electron transfer, proton transfer and proton-coupled electron transfer reactions. Such excited-state dynamics are typically described by employing femtosecond transient absorption and emission spectroscopic techniques. However, we focus on a structural perspective, essentially with an aim to unravel the intricate structural dynamics associated with excited-state electron and proton transfer processes by employing the ultrafast coherent Raman and IR spectroscopic methodologies. Some of our interests are directed at

1. Deciphering the early-time events of photo-initiated proton-coupled electron transfer reaction pathways involving photoacids and photobases
2. Development of multidimensional ultrafast spectroscopic methods
3. Elucidation of electronic and vibrational quantum coherences
