Academic Profile

Dr Ashok Kumar Mishra completed his Master of Science from University of Delhi in 1980 and received his Ph.D. from IIT Kanpur in 1985. After a stint in Sambalpur University as a faculty member in Chemistry, and in Gunma University (Japan) as a Monbusho fellow, he joined IIT Madras in 1992. He was also a JSPS Visiting Scientist in Gunma University, Japan during 2002-2003. Currently he is a Professor in the Department of Chemistry, IIT Madras. He is the recipient of CRSI Bronze Medal from the 'Chemical Research Society of India' and a Fellow of the 'National Academy of Sciences, India'.

He works in the general area of Physical Photochemistry and Fluorescence Spectroscopy. He has an active research group. So far he has guided 16 Ph.D.'s, many M.Sc. students, and has published about 115 research papers, reviews and monographs.

    Research Interests

    In the general areas of Fluorescence Spectroscopy and Physical Photochemistry, Dr Mishra's research group has been working on a variety of diverse systems and problems, ranging from basic photophysical studies to newer applications of fluorescence. Two major directions in recent years have been (i) Developing novel paradigms for understanding the fluorescence behavior of complex multi-fluorophoric systems, and (ii) Developing fluorescent molecular probes for organized media based on various photophysical concepts.

  • Excitation-Emission-Matrix Fluorescence (EEMF), Synchronous Fluorescence Spectroscopy (SFS) and Total Synchronous Fluorescence Spectroscopy (TSFS)
  • Integration of Chemometry with fluorescence based analytical methods
  • Design and development of Fiber optic based fluorimetric techniques
  • Use of White light excitation fluorescence (WLEF) as a low cost, fast response alternative in fluorimetric instrumentation
  • (ii) Developing fluorescent molecular probes for organized media based on various photophysical concepts
