My group is involved in experimental physical chemistry research with particular emphasis on laser spectroscopy, ultrafast spectroscopy, biophysics, spectroscopy of materials, chemical education and analytical spectroscopy. Myself is currently involved in the development of fluorimeter prototype for sensitive detection and estimation of Arsenic pollutants in water with the help of our own developed quantum dots. We are in the process of developing quantum dot based systems for biological applications.
