Brief Introduction:
My work mainly involves the generation of the mid-IR spectrum (2-10 micron) and applying it to unravel the ultrafast energy dynamics of 2D materials and their related field and probing the bio-physical polymer system.
The approach I followed is mid-IR pump-probe Spectroscopy and 2DIR spectroscopy. Both are Nonlinear Spectroscopy.

Research Interests
Ultrafast Mid-IR Pump-Probe Spectroscopy:
Ultrafast Mid-IR pump-probe spectroscopy is a non-linear phenomenon associated with 3rd order non-linearity. We use femtosecond visible pumps on TMDs like MoS and WS and study their ultrafast carrier dynamics in the Mid-IR region. This help to understand the formation of dark excitons and excitons' fine structure.
​
Dual Frequency 2DIR Spectroscopy:
The 2DIR method is capable of measuring structural constraints for various molecular systems in condensed phases. Dual Frequency 2DIR setup permits measuring long-range bond connectivity patterns in molecules, energy transfer pathways, and their rates. This 2DIR spectroscopy itself is an interdisciplinary area that can unravel the dynamics in bio-molecular complexes, triggered the chemical reaction, allows to study of the energy pathways,
