Professional Experience:
* 1998 June-present: Post Doctoral Research Associate, University of North Carolina, Department of Biochemistry & Biophysics, Chapel Hill, NC-27599, USA.
Preparation and characterization of leakage free liposomes and encapsulation of drug like molecules.  Development and design of new lipid mixing assay.  Details molecular mechanism of membrane fusion in presence of peptides (HA and HIV) and poly(ethylene glycol) based on time kinetics and proposed a novel hypothesis for membrane fusion events.

* 1997 Sept.-1998 May: Post Doctoral Research Associate, Institute of Chemistry, Academia Sinica,Taipei, Taiwan.
Synthesized two short chain peptides representing HIV protein and influenza respectively using automatic protein synthesizer and purified by HPLC.  Structural changes occurred during membrane binding was determined by NMR, CD and fluorescence.  A novel model was proposed for understanding the mechanism of membrane fusion by HIV protein.

* 1996 Nov.-1997 Sept. : Post Doctoral Research Associate, Saha Institute of Nuclear Physics, Department of Nuclear Chemistry 1/AF Bidhannagar, Calcutta-700-064.
Structural biology of proteins (HRP, HSA) in presence of denaturants.  A detailed study was carried out to understand the role of denaturants in protein folding.
Developed a novel method for determining the hydrophobic pocket of protein by pyrene fluorescence

* 1991 Dec.-1996 Oct. : Ph.D. work, Indian Association for the Cultivation of Science, Polymer Science Unit,  Jadavpur, Calcutta-700-032, India.
Surfactants and Polymer Chemistry, Dissertation: "Physicochemical properties of Mixed Micelle Formation and Polymer Surfactant Interaction".  Extensive studies on surface and bulk properties (CMC, polarity, aggregation number, area per surface active molecules, surface excess, thermodynamics of micellization and adsorption) of mixed surfactant and polymer-surfactant systems.
