Present Research Interest:

 

Laser induced optoacoustic spectroscopy (LIOAS), laser spectroscopy, steady-state and time-resolved fluorometric study of the photophysical and photochemical processes (ESPT, ICT, electron transfer, charge transfer and energy transfer) in homogeneous as well as microheterogeneous environments, theoretical modeling and simulations of photophysical and/or photochemical observations, fluorescence sensing.
