In his five year-tenure, Dr. Rajadurai received Best Professor Award in 1983, for his perfect attendance. He also received the elocution competition award among the faculties of Loyola College in 1984. The best testament to the circularly parallel power of Tamil from ancient generations to now is the journey of Rajadurai from India to America & America to India (1985-2009). While revolutionizing the field of catalysis in U.S. universities and corporations, Rajadurai converted his stature to highlight the values for Innovation. While living in US, he continuously supported rural agriculture development in Tamil Nadu and also automotive technology development in India. In the United States of America, He began his career with research associate professor position at the University of Notre Dame, working also in a number of advanced laboratories around the nation. His associates included Professor J.J. Carberry and Professor C.B. Alcock, with whom he collaborated and developed non-noble metal catalyst and solid oxide solutions, including one rivaling platinum for oxidation and reduction reactions. He was the invited guest of the Royal Chemical Society of London 1989 at Liverpool, UK. At the University of Notre Dame, he was in charge of catalysis laboratory at the chemical engineering Department and supervised 2 graduate research projects. At Bowling Green State University, Dr. Rajadurai’s research was focused on synthesizing, characterizing and studying photochemical and photo-physical properties of organic free radicals. Dr. Rajadurai completed certificate course in Finance and Marketing Administration from Bowling Green State University, Ohio (1987), focusing primarily on closing the gap between innovative scientific research and industrial implementation. Dr. Rajadurai published high-profile scientific theories & applications in the area of chemistry, nano-second kinetics of free radicals, electron and energy transfer reaction kinetics, chemical reactor engineering, computational fluid dynamic analysis, finite element analysis, mechanical engineering, catalysis, emission control and exhaust system design, development, validation and manufacturing. Dr. Rajadurai transitioned to corporate business in 1990, with a series of senior scientist and executive positions. Dr. Rajadurai joined the Carus Chemical Company, Ottawa, IL, USA as a Senior Research Chemist by April 1990. At Carus Chemicals, he developed a one-step process for Carulite oxidation catalyst formulation and ozone destruction catalyst for copy machine application. He also developed the powder catalyst coating technique on cordierite honeycomb, poly-urethane celcor foam and zirconia foam substrates. Subsequently, at MOTEC – a subsidiary of Cummins Power Generation, Dr. Rajadurai, as a Director of Research, led catalyst development, reactor designs and the process of fabrication and analytics – resulting in solutions for NOx reduction systems (SNCR, HC SCR) applied in diesel operated engines. To name a few, he was an executive team member for the implementation of Cummins Technical System (CTS), a six year product development cycle, to Define, Design and Develop diesel engines along with exhaust after treatment system. In 1994, his team developed the first North American diesel oxidation catalytic converter to comply with the U.S. emission regulation, packaged and released in Cummins B5.9L diesel engine for Chrysler Dodge vehicle. He successfully managed Industry-University Research activities at Cummins-Notre Dame, Cummins-University of Washington, Cummins -Texas A&M, and Cummins-Oak Ridge National Laboratory. Dr. Rajadurai was also the Cummins Corporate Facilitator of Stephen Covey’s “Seven Habits of Highly Effective People.” He was the Director of Advanced Development at Tenneco Automotive between 1996 and 2002. Dr. Rajadurai’s leadership tenure at Tenneco established computational modeling to develop exhaust system applied in the commercial, heavy duty specialty and global emerging markets. His unique responsibility includes the development of the first North American manufacturing of the ultra-thinwall substrate catalytic converter. He became a Member of the BMW emission technology brainstorming team, 1998. He was honored with the Tenneco Corporation General Manager’s Leadership Award, Innovation Award, Vision Award and also recognized as “Mr. Converter” and “The Standing Innovation.” Dr. Rajadurai also led the global design and supply teams and managed strategy on exhaust system development for Low Emission Vehicle (LEV), Ultra Low Emission Vehicle (ULEV), Super Ultra Low Emission Vehicle (SULEV) and Partial Zero Emission Vehicle (PZEV) systems. He was instrumental to starting Walker Exhaust India, where he represented as a Member of the Board of Directors. Being intimately engaged with senior leadership of several American companies, he accepted ArvinMeritor Inc.’s offer to serve as its Director of Emission Strategies. There, he paved the way for establishing Technology and Product Development Road Map for Emissions Systems and related products. He assisted implementing advanced CFD modeling in ArvinMeritor Technical Support Centre, Bangalore, India and trained engineers. In 2004, he was recognized by Pravasi Bharatiya Diwas as Scientist and Technologist of Indian Origin. Dr. Rajadurai worked as Vice President at ACS Industries from 2004 to 2009. He started a high-profile Research & Development facility in Boynton Beach, Florida for catalyst development, characterization, testing and validation for small engines and diesel powered applications. He developed computer modeling for catalytic converter optimization and designed wire mesh thermolyzer/mixer, seals, mounting materials and catalyst carriers. Dr. Rajadurai has held leadership positions as the Board of Directors for the U.S. Fuel Cell Council, Manufacturers of Emission Control Association (MECA), Chairman of MECA Committee on Advanced Technologies and Alternate Fuels and Walker Exhaust India Pvt Ltd. Dr. Rajadurai is an elected fellow of the Society of Automotive Engineers and a Life Member of the North American Catalysis Society, North American Photo Chemical Society, Catalysis Society of India, Instrumental Society of India, Bangladesh Chemical Society and Indian Chemical Society. He returned to India after 25 years of stay in the US and joined Sharda Motors Industries Ltd. in 2009 as Head of Research & Development. In this role, he has built a pre-eminent Research Development Centre in Chennai for Sharda Motor Industries Ltd. He has found great success in promoting individuals with a full range of professional knowledge and exposure and also experience in corporate culture to deliver technical solutions effectively. Dr. Rajadurai has been invited by governments and a range of private sector senior executives to discuss catalysis-at-large, most notably as a member of the Core Group Automotive Research. Dr. Rajadurai has received numerous awards and honors of distinction throughout his career.
