"PhD positions are open !! Highly motivated candidates with valid CSIR/UGC-JRF can contact us anytime in the year."

Main objective of our research group (LBCS) is to investigate chemical and biological macromolecular systems using spectroscopic, microscopic and computational methods. We use fluorescence based steady state and time resolved spectroscopy and microscopy techniques to understand interactions between key biomolecules such as proteins, DNA and RNA.

Our research objectives include;

    Characterization of the excited-state photophysical properties of molecules.
    Fluorescence spectroscopy and structural dynamics of serum and milk proteins.
    Biophysical analysis of protein-DNA/RNA interactions.
    Structural and dynamics impact of epigenetic modifications on DNA.
    Development of chemical tools for biomolecular imaging and biosensing applications.
    Exploring the luminescence behavior of nanomaterials such as graphene oxides, carbon dots and nanocrystals.
