Research

Major contribution has been establishment of a laboratory at RRCAT for directed basic research on the development and utilization of optical techniques for biomedical imaging, diagnosis and therapy. Major achievements in this area include (i) Development of spectroscopic systems that have been used at Hospitals in Indore as well as at Tata Memorial Hospital, Mumbai for non-invasive screening of the cancer of oral cavity with promising results. (ii) Development of Optical Coherence Tomography setups with different functional extensions and their use for non-invasive, high resolution (~ 10 µm) biomedical imaging applications e.g. monitoring of the healing of wounds; (iii) Development of novel laser micromanipulation techniques for optical transport and rotation/orientation of intracellular objects; use of optical tweezers for applications like, malaria diagnosis, transfection, Raman spectroscopy of single trapped cell, etc.; (iv)The use of Chlorin derivatives synthesized in house for the treatment of cancer and for healing of antibiotic resistant bacteria infected wounds in both healthy and diabetic animal models. Further, as Head of Laser Materials Development and Devices Division and Laser Biomedical Applications and Instrumentation Division, RRCAT supervised programs on (a) growth of laser host material and nonlinear optical crystals, (b) development of Pt loaded carbon aerogel based catalyst for H/D exchange (c) development of instruments for remote measurements and metrology in high radiation environment, and (d) looking after the scientific responsibility of RRCAT in the Indo - US project on setting up a Laser Interferometer Gravitational Wave Observatory (LIGO) in India in its initial phase.

Earlier contributions were on the generation of tunable coherent radiation in mid infrared region by non-linear frequency conversion and optically pumped molecular gas lasers for which received the N S Satyamurthy memorial award of Indian Physics Association for the year 1988. Other awards received include the 1998 Homi Bhabha Science and Technology Award of the Department of Atomic Energy for contributions in the area of biomedical applications of lasers, the annual award of the Society for Cancer Research and Communication for the year 2006, group achievement awards of DAE for the years 2012 and 2013 and Homi Bhabha National Institute Distinguished Faculty Award for the year 2015.
