Senior Technical officer



Joined the chemistry department, IIT Madras in 1991 as a Technical Assistant and now serving the department of Chemistry as a Senior Technical officer. A Ph. D. from IIT Madras, under Prof. Ramesh Gardas in the in-situ cryo-crystallization of ionic liquids. Working in the single crystal X-ray diffraction field 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 Bruker Apex II workshop, in Germany, in September 2012, and became a certified APEX II user. The experience involves in the structural determination of organic, inorganic, and hybrid organic-inorganic material as well as organometallic molecules in addition to dealing with supra molecular systems which involved crystallographic disorder and twinning problems. This is followed by the finalization of the structure and contribution to its publication as collaborative work.
