Shelly John Mechery, PhD, Team Leader, has over 11 years of experience in developing optical sensors for measuring physical, chemical and biological parameters using fluorescence and evanescent wave spectroscopy. He has extensive research experience in the field of nanoparticles (dye-doped silica nanoparticles) and their bioanalytical applications. Shelly has developed surface immobilized biomolecular probes (molecular beacon (MB), linear DNA FRET probes) for DNA and RNA detection at single molecule level. Confocal microscopy, fluorescence correlation spectroscopy (FCS) and flow cytometry are other areas of his expertise. He received his doctoral degree from Cochin University of Science and Technology (CUSAT), Cochin, India in 2000. Soon after his doctoral work, he joined Nanyang Technological University (NTU), Singapore as a Research Fellow. At NTU he worked in the area of Fiber Optic Chemical Sensors (FOCS) and biosensors. He designed and developed a fiber optic bacterial sensor to monitor 'streptococci mutans' in human saliva for the early detection of dental carries. He also designed Fiber Optic Polarimetric Sensors (FOPS) and Fiber Bragg Grating (FBG) for structural health monitoring. During his tenure at Diagnostic Instrumentation Analysis Laboratory (DIAL) at Mississippi Sate University, he developed a fiber optic gas sensing system, to monitor NO₂ in the parts per billion ranges. He has published over 15 peer-reviewed scientific articles in leading national and international journals, contributed in book chapters, and has 3 U.S. patents pending.
