Hi,

   I am a theoretical physicist working in the general area of non-equilibrium statistical physics and its application to some interdisciplinary fields. My interests include Non-equilibrium phase transitions, Novel correlations in  non-equilibrium steady state , Exactly solvable  driven diffusive systems,  Structure and functionig  of Networks.

    Classical non-equilibrium systems  do not ensure existence of the  state functions like Hamiltonian and entropy as these systems are  known to have  non-zero current in the configutaion space.  Thus the steady states of these systems posses interesting and non-trivial  correlations which are usually absent in equilibrium.  My current research interest is to unfold these  novel correlations.

    One of the striking features of these systems is that they can exhibit phase transitions even in one spatial dimensions. Surface roughening, wetting, synchronization, extinction and reaction diffusion systems show a very special kind of non-equilibrium transition into absorbing states which generically belong to the directed percolation universality class. However, there are several systems which show exceptions and our group focuses at characterising these unusual critical behaviours.

    In the application front, our group works, in collaboration with experimental bio-physicists, to understand the underlying structure existing in bio-molecular networks. It is well known that short non-coding RNAs, called micro-RNAs, target most of the human genes and crucially regulate the gene expression. Possibly the genes are better regulated by co-targeting of clusters of miRNAs, compared to the single ones.  We aim at finding such community structures existing in the miRNA co-target network of human and other species.
