Biographic Sketch:
Dr. John Prakash obtained his PhD from Indian Institute of Technology, Madras in 2013. His major areas of research include analytical fluorimetry, development of modular spectroscopic instrumentation for environmental and biologically relevant systems as well as application of chemometrics tools to spectroscopic data. He is the recipient of the Lilly Award for the Best Thesis from the 'Eli Lilly and Company Asia'. He has introduced a novel spectroscopic technique, White Light Excitation Fluorescence (WLEF) for multipurpose applications. He is very passionate in the area of specialized spectroscopy techniques like laser spectroscopy and Imaging. He is motivated to teach Physical and Theoretical chemistry topics and want to bring my enthusiasm and sense of confidence to the organization and to the people I work with. His involvement in various areas of activities at college has taught me crucial lessons on leadership & teamwork. Also, He had opportunity to responsibly carry out laboratory experiments (mainly physical and gravimetric) last 9 years. As part of curriculum, he has guided one MPhil thesis, 38 PG, 12 UG, and 7 PG Diploma dissertations. He is also a recipient of Certificate of Excellence in Reviewing -2021 by Indian Journal of Science & Technology.

Research Highlights :

  • Inventing, developing, and validating a novel technique for chemical analysis:  White Light Excitation Fluorescence (WLEF) emitted from the excited sample is measured and then analysed to determine the quality of complex and transparent analytes.
  • Design & Fabrication: Constructing a portable, low cost, modular, and highly sensitive optical Multipurpose spectrophotometer for the simultaneous measurement of the absorption and fluorescence spectra of samples
  • Remote and Onsite Monitoring: Modifying the WLEF instrument using a dip-probe fiber-optic spectrometer to quantify analytes remotely.
  • Multiparameter Sensors: Design of multi-parameter chemo-sensors to address environmentally relevant issue.
  • Multivariate Analysis: Exploring the strength of chemometrics to address real samples
