Dr Suman Kumari Mishra, the Director of CSIR-CGCRI, is a materials scientist specialised
in advanced materials process- ing, material properties and applications. She completed
her PhD from the Indian Institute of Technology, Kharagpur, and was also the recipient of the University Gold Medal of Ranchi University in 1985 for ranking 1st in class, first in the batch. On the professional front, she rose to the level of Chief Scientist with the CSIR-National Metal- lurgical Laboratory (CSIR-NML), Jamshedpur. She was also Dean of Engineering Sciences with the Academy of Scientific and Innovative Research (AcSIR) for several years.
Dr Mishra is an elected fellow of the National Academy of Sci- ences of India and has received several awards in recognition
of her scientific contributions. These include CSIR Raman Fel- lowship, CSIR Young Scientist Award, Vasvik Award, Best Metallurgist of the Year Award by Ministry of Mines and MRSI Medal, among others.
Dr Mishra has published more than 100 papers, she has to her credit 13 patents, contributed seven book chapters, trans- ferred two technologies, handled around 25 sponsored projects, guided seven PhD students and also a large number of students for their graduate and post-grad- uate dissertations. She has also been a member of the Interna- tional Editorial Board of the IIM- Universities Press and Defence Science Journal, DRDO.
  evaluation, training and education are provided to national industries through technical projects. Apart from these, social connect programmes comprising skill development, training and demon- stration etc meant for rural sectors are also undertaken on regular basis to pro- mote self-employment for rural people and their socio-economic benefit.
R&D at CSIR-CGCRI is under- taken in the following interconnected domains:
· Glass and Specialty Glass
· Fibre Optics and Photonics
· Functional Materials
· Bio-ceramics
· Renewable Energy
· Ceramic Membrane Technologies
· Non-Oxide Ceramics
· Refractories
· Materials Characterisation
· Coatings and Composites
· Potteries, Tiles and Rural Industrialisation
CSIR-CGCRI is one of the key com- ponents for national innovation space when it comes to providing technologi- cal inputs for the strategic as well as ci- vilian sectors.
Atomic energy, defence and space are among the major stakeholders in the strategic sector. Industrial applica- tions covering civilian stake- holders include telecom,
steel, energy, healthcare, power and water among others. A few important achievements include:
· Radiation Shielding Glasses: The technology has produced high density RSW glass using the platinum pot bot- tom pouring flow casting technique to produce glass blocks of varying dimen- sions. Efforts are currently on to switch towards specialty clay-based refractory crucible that works on tilt casting.
· Glass Beads for Immobilisation of Nuclear Waste: A process technology has been developed that makes custom- ised glass nodules in a five-component borosilicate glass matrix to be used as feed base glass in high temperature Joule Melter to produce vitrified product. The technology finds application in immobil- ising high level liquid nuclear waste in nuclear reactors.
· Chalcogenide glasses: Known for their extended infrared transmission upto 20μm, chalcogenide glasses are indis- pensable for IR optical components and thermal imaging. The institute has es- tablished moderate facilities for devel- opment of such glasses with stipulated specifications.
· Ceramic EM Windows for strategic applications: The technology is aimed at producing reaction bonded silicon nitride EM windows for stipulated ap- plication in the strategic sector
· Specialty Optical Fibres: Several types of specialty optical fibres have been developed. These include Er doped optical fibre for low power optical amplifier(CATV application); Er-Yb co- doped optical fibres for high power opti- cal amplifier (free space communication and FTTH); photonic crystal fibre for super-continuum light source in confo- cal microscopy; and germanium doped optical fibre for making of FBG based components
· Fibre Lasers: Various types of fibre la- sers have been developed for industrial and medical application that include Yb- doped lasers (industrial application), Tm-doped lasers (medical application in surgery) and Distributed Feedback (DFB) fibre laser for making of fibre- based hydrophone.
· Superior refractories: Technologies for
