Academic Qualifications:

 Area of Specialization:         

      Our academic research broadly covers physico-organic, bioorganic and biophysical chemistry. For last five years our group research activity is mainly focused on the design and synthesis of some novel organic, organo-metallic framework and inorganic functional materials, scaffolds, fluorophores, fluorescent probes, good chromogenic and fluorogenic chemosensors and biosensors to detect heavy and transition metal ions, anions and biomolecules like important amino acids, nucleic acids, protein and carboxylic acids. The optoelectronic behaviors of some of molecules have been utilized to construct logic devices such as logic gates and molecular security keypad lock systems. We use different spectroscopic techniques to characterize and establish the basic mechanisms (reaction as well as photophysical mechanism such as ICT, PET, FRET, MLCT, EET etc.) These molecules have also been explored as a fluorescent tag to label biomolecules (DNA/RNA/Protein) and for noncovalent interaction studies. Synthesis of nucleoside analogues and covalent attachment of fluorophores with oligonucleotides for homogeneous hybridization studies in DNA diagnostics and related biophysical studies. Some heterobifunctional reagents have also been developed to immobilize biomolecules on the solid surfaces as well as to construct oligonucleotides/protein microarrays for diagnostic purposes. Under my supervision five Ph.D. and twelve M.Sc. students have completed their research/project work. Our research group has contributed good research papers with total citations: 300 (Impact Factor: 125; H-index: 10)
