Brief Biodata:

Dr Nirmalya Karar did his B.Sc (Phys Hons) from the illustrious Scottish Church College of Calcutta University in 1993. He got his M.Sc (Phys) from the Indian Institute of Technology, Kharagpur in 1995. He was at the Raman Research Institute Bangalore for a year (1995-96). He worked on his PhD at the Materials Science Centre of the Indian Institute of Technology, Kharagpur (1996-2001) under Professor S Basu in the area of growth and characterization of III-V bulk alloy materials. During this period, he was also trained at the Tata Institute of Fundamental Research Mumbai under Professor B M Arora. He then went for a brief Post Doc activity at the Nanotechnology Centre, CSIC, Madrid, Spain on nano-contact formation. In 2002 he was awarded the CSIR-Research Associateship and initially worked at IIT-Delhi in the area of luminescent nano-materials and from 2003 onwards he worked at CSIR-NPL as CSIR-Research Associate in the area of II-VI and other luminescent nano-materials and their characterization, including Surface Analysis. In 2006 his services were regularized as a Scientist and he continues to serve CSIR-NPL till date. In 2009, he was awarded the DST sponsored Indo-US Fellowship with the specific mandate to train and work in the area of Surface Analysis (XPS & TOF-SIMS) for a year at the University of Delaware under Professors Robert Opila and Thomas P Beebe Jr.

Dr Karar has completed a DST Fast Track project and a CSIR-EMPOWER project (in the area of TOF-SIMS as a forensic technique). He has expertise in wet chemical etching of inorganic materials. He has also worked earlier on nanostructured alloy materials and analysis of their properties (including EM abs).

His current R & D interests are (among others), (i) in the usage of such Surface Analysis techniques to understanding the unusual degradation of metal alloys and other materials; (ii) Surface Analysis of various polymeric materials for their practical application prospects.

He has authored more than thirty papers in national and internal journals of repute, including single authored papers and has also written a book chapter based on the above activities.
