Area of specialization:
 

My main research interest lies in understanding the properties of interstellar dust and interstellar Polycyclic Aromatic Hydrocarbon (PAH) molecules. I am interested in theoretical, observational and experimental spectroscopy of dust & PAHs using a multi-wavelength approach. I also have interest in astrobiological implications of these studies. On a wider perspective, I have interest in observational and theoretical modeling of interstellar dust, and theoretical and experimental spectroscopy of astrophysical molecules.
I am also working in exploring UV properties of the interstellar and intergalactic medium.
