Visiting Academic

  • May 2017-July2017: Visiting Academic at the University of New South Wales, Sydney, Australia
  • April 2015-Present: Assistant Professor at Centre for Polymer Science and Engineering, Indian Institute of Technology Delhi, India.
  • Jan 2011-April 2015: Senior Scientist at Goodyear Tire & Rubber Company, Akron, Ohio, USA.
  • Sept 2007-July 2010: Scientific coworker in the group of Prof. Christopher Barner-Kowollik (PhD research work), Karlsruhe Institute of Technology, Germany. During PhD, research work was focused on orthogonal modification of solid substrates via a combination of Reversible Addition Fragmentation Chain Transfer polymerization and hetero Diels-Alder (RAFT-HDA) chemistry.
  • Sept 2006-May 2007: Scientific coworker in the group of Prof. Hans-Juergen P. Adler and Prof. Dirk Kuckling, Technical University Dresden, Germany, Prof. Veena Choudhary (IITD advisor) (research work for fulfillment of credits for M.Tech degree). Here research was aimed at preparing metal ion sensitive hydrogels which can find application as sensors (specifically piezo-resistive sensors).
  • May 2006-Aug 2006: Scientific coworker in the group of Dr. Josemon Jacob, Indian Institute of Technology Delhi, India (research work for fulfillment of credits for M.Tech). The project aim was to prepare soluble analogues of polyphenylene sulfide (PPS). Fluorene derivatives were modified by the introduction of solubilizing alkyl groups. Direct polymerization and polymerization by modification to dithiols and coupling in presence of palladium catalyst were attempted.
  • April 2004-June 2005: Scientific coworker in the group of Prof. Y. C. Joshi, Department of Chemistry, University of Rajasthan, Jaipur, India. Junior Research Fellow on University Grant Commission funded project on synthesis of novel heterocycles which can serve as potential chemotherapeutic agent.
  • Industrial Collaboration during PhD: Evonik Industries, Germany for the development of novel coatings and adhesive materials.
  • Academic Collaboration during PhD: March 2008-June 2008 - Scientific coworker in the group of Dr. Suzanne Smith, Australian Nuclear Science and Technology Organization (ANSTO), Australia where radioisotope labeling experiments were carried out to understand and quantitatively estimate accessible number of reactive groups available for functionalization on the surface of microspheres
