A. Current Research Interest-     Somendra Mohan Bhattacharjee

  • Is it possible to develop a dynamical description for the replication of DNA?

    The DNA Replication process is a co-ordinated (or is it correlated? ) action of a large number of "polymeric objects" over long scales both in length and time (whole length of DNA, in minutes). As opposed to the biological base by base description, our philosophy is to consider minimal coarse-grained models.

    Our starting point is the unzipping transition of DNA
              -a phenomenon whose existence was first shown theoretically from Bhubaneswar.
    Our choice: Velocity selection is one criterion to quantify or define "co-ordination".

    Still, a bother: Is there something that can be called a minimal biology?

  • As yet there is no indication that biology needs any new law that is still not known in "physical sciences". What is missing is more of our understanding of nonequilibrium situations in general. The connection between equilibrium and nonequilibrium is another topic of interest.

    • B. Nonphysics:

    Immensely enjoyed finding a unique solution to the vexing issue of positions of short vowels (i-,e-,oi-,o-kar etc) in the transliteration of romanized assamese, bengali, and oriya, especially for LaTeX.
    This also led to the development of web-based search programs that are now functional since 2002. The fully searchable gitobitan was made operational in 2002. Currently the repertoire, with help of a few, espeially Sudipta Mukherji, includes many other classics and folk songs in bengali and oriya. How many languages can it be extended to?
