He is also a member of the editorial boards of several reputed scientific journals published by institutions such as the Indian Academy of Sciences.
His research topics include path integral representation of Fractional Brownian motion, ring closing opening dynamics in polymers, first passage time calculation in phase space, energy transfer between molecule and graphene, quantum coherence etc.
He also developed the time dependent version of the coupled cluster theory (CCT) and applied to a problem of ion neutralization scattered from a surface of a metal.
He has also proposed an analytical model to elucidate the mechanism of protein transport across the nuclear pore complex.
More recently he has started working on Levy flights which involves long jumps and on the dynamics of a tracer in a heterogeneous medium, where diffusivity is a fluctuating quantity.
