Expert is the President and Founder of  a consulting firm offering Research and Product Development services to corporations. Expert is a Research Scientist and Product Development professional with extensive knowledge in the Graphic Arts (Printing), Photopolymers, and UV Cure, Polymer Chemistry, and Specialty Coatings industries. He also has extensive experience in international business practices. He has a proven track record in innovation with over 36 US patents/applications and 60+ European and PCT patents and is conversant with all aspects of product development from concept to market. He brings a well-rounded background of corporate experience and educational credentials (Ph.D. in Polymer Chemistry and an Executive MBA). Expert 5240 has continued his commitment to innovation by working on projects as diverse as use of microreplication for radiation cure systems, Elastomers for Direct Laser Engraving for relief printing applications, and development of a portfolio of solvent-based, water-borne and UV curable coatings, which has resulted in several patents.
Prior to, Expert was Research Project Manager in the Plates Division for Macdermid Printing Solutions. During his tenure there (1995-2005), he headed a number of critical research initiatives in Digital and In-the-Round (ITR) Flexography, identifying several key technologies for continued growth of the flexographic market and Macdermid’s market share. This effort resulted in more than 10 US patents and several (5+) commercial products. He led a team of technicians, associates, and engineers, developing his staff and guiding them in both company and independent research projects. Expert 5240 also served as liaison for the corporation’s patent attorneys for intellectual property protection and development.
From 1990-1995, Expert was affiliated with W. R. Grace & Company as Research Chemist, Designed Polymers Research, in its Washington Research Center. During this stint, he designed and developed several novel water-dispersible elastomeric photopolymers using anionic polymerization, which resulted in several patents. Earlier career experiences included a yearlong assignment at AT&T Bell Laboratories as a post-doctoral Member of the Technical Staff. There he trained in microlithography, which laid the foundation for his subsequent work in photopolymer chemistry. His initial work helped pave commercialization of AT&T Bell Laboratories’ CAMP-6 Photoresist circa 1992.
His international experience includes work in Europe, Asia Pacific, and South America. In addition to completing his undergraduate work in India, Expert served as a Visiting Scientist at Johannes Gutenberg University in Mainz, Germany under a NATO grant. He has also collaborated with scientists in France, Switzerland, China and Japan on ongoing research projects. Expert is the author of numerous scientific and business publications and white papers published in journals such as Macromolecules, Chemistry of Materials and SPE Conference etc.
Expert’s educational credentials include a Ph.D. in Polymer Chemistry from the University of Florida, an MBA (Executive Program) from Georgia State University, and a B.Sc. (Technology) in Chemical Technology from Bombay University’s Department of Chemical Technology (UDCT).
