polymers and natural light harvesting systems using both steady state and
time resolved absorption and fluorescence spectroscopy. I also have research
experience in fluorescence probe studies of polymers, micelles and reversed
micelles, and inorganic surfaces. I am at present working as a postdoctoral
research
associate at the Department of Chemistry at the University of Connecticut.
This position is
available till the end of March 2000.
Please find below my curriculum vitae and list of publications for favor
of your perusal and
