Senior Professor
Saha Institute of Nuclear Physics

I work on structure and dynamics at interfaces of soft materials and nanomaterials. Recently I have become interested in biomaterials and in pattern evolution. My special interests have been in the metal-organic interface and the evolution of structure in organic films on water surface.

Biography

I was born in 22 August 1957 in a town called Coochbehar in the state of West Bengal, India but I have lived in the metropolis of Kolkata since I was a few months old. I passed out from school in 1975 and did my graduation (BSc) with Physics major and Chemistry and Maths as minors from St Xavier's College (Calcutta University). I did my Masters in Physics from Calcutta University in 1980 and joined Saha Institute of Nuclear Physics as a Research Fellow working on Microwave Spectroscopy of molecules as my dissertation topic. My PhD was awarded in 1989 by Calcutta University and I joined Saha Institute as a Lecturer in the Solid State and Molecular Physics Division in 1990. I did some work on coupling of intense radiation to matter and then shifted my interest to Langmuir monolayers in 1992, where I and my friend Sujata Modak predicted in 1994 the formation of a 2D lattice of counter-ions beneath a Langmuir monolayer of fatty-acids that was experimentally corroborated by the group of Als-Nielsen in that year. In 1996, I and my senior colleague Milan Kumar Sanyal set up a laboratory to study surfaces and interfaces by x-ray scattering and scanning probe microscopy, where we showed for the first time that molecules in a polymer film below a certain thickness spontaneously form layers parallel to the surface, a phenomenon that was found also to happen in a simple liquid by me with co-workers in the laboratory of Pulak Dutta in Northwestern University, USA, during my postdoctoral stint from 1998-2000.

The influence of nanoporous aluminosilicate nanoparticles (NP), citrate-capped gold NP, lipophilic silica NP, BSA-capped silver NP, and lipophilic zinc oxide NP were studied on 75 cell cycle-related genes of adult Drosophila melanogaster. Data showed that silver, zinc oxide, and alumino silicate NP predominantly perturbed cell cycle genes, whereas gold and silica NP exerted the least influence on these genes.
