Born in a remote village near Sivaganga town. Moved to Chennai during the year 1966 and joined K.V. C. L. R. I., Adyar for schooling till 12th Standard. Obtained B. Sc from A. M. Jain College, Meenambakkam, M. Sc from Kuvempu University and M. C. A from Bharathidasan University. Pursuing Ph. D under staff category guided by Dr. Ramesh Gardas. Joined Department of Chemistry, IIT Madras in the year 1991 as Technical Assistant and now serving the Department of Chemistry as Technical officer. Working in the field of single crystal X-Ray Diffraction on the state-of-the art Bruker Kappa APEX II with 4-circle technology since 2005 and responsible for its operation and maintenance. Underwent training in Bruker AXS, Delft, Netherlands in October 2007 as well as a specialized BrukerApexII workshop in Bad Herrenalb, Germany,September2012and became a certified APEX II user. Experience involves in structural determination of organic, inorganic, hybrid organic-inorganic material as well as organometallic molecules in addition to dealing with supra molecular systems which involved crystallographic disorder as well as twinning problems. This is followed by finalization of the structure and contribution in its publication as collaborative work.
