Research Interests

​My research interests have been mainly focused on understanding the chemistry of thermo-catalytic conversion of variety of feedstocks to value added chemicals. Valorization of lignin for the production of valuable chemicals. Theoretical (Density functional theory or molecular modelling) and kinetic modelling of complex reaction systems.
