Jai Singh is a Professor of Physics at the School of Engineering and IT, Charles Darwin University, Australia. He is an internationally recognised theoretician in the field of excitonic processes in condensed matter, both bulk and nanostructures, optoelectronic properties of thin film organic and inorganic solar cells, organic light emitting devices and scintillators. He has made significant contributions to the literature in these fields with 200 research articles and two research monographs: (i) Excitation Energy Transfer Processes in Condensed Matter (Plenum, 1994) and (ii) Advances in Amorphous Semiconductors with K. Shimakawa (Taylor and Francis, 2003). He has also edited a book Optical Properties of Condensed Matter and Applications (John Wiley and Sons, 2006). He has held numerous visiting posts around the world, including Germany (Max-Planck Institute and Hahn Meitner Institute Berlin), Japan (as a JSPS Fellow) and USA (UC-San Diego and Lawrence Berkeley National Laboratory, Berkeley).
