He assumed the mantle from our visionary founder, Dr. Tom Morel, who now serves as Chairman of the GT Board of Directors. With 30 years of experience and an enthusiast of simulation technologies, he has collaborated with pioneers across diverse industries transforming the state of the art for the digital development of complex products and systems. Prior to GT, he held executive global leadership roles in software organizations and his professional journey has been shaped by experiences that transformed a CAE startup (HKS, Inc.) into an exciting growth company (Abaqus, Inc.), and later to the development of a premier simulation brand (SIMULIA) at Dassault Systèmes. He is passionate about making CAE the preferred way to drive industry innovation and create a more sustainable future for the next generation. He is a member of the Governing Board of Directors at the Bulletin of the Atomic Scientists.

Originally from Pune, India, Mr. Shah lives in Chicago, Illinois, with his family. He earned his bachelor’s degree in mechanical engineering from COEP Technological University in Pune and a master’s degree in mechanical engineering from Stony Brook University in New York.

founder & chairman of the boardTOM MOREL

Dr. Morel co-founded Gamma Technologies in 1994 with the vision of developing a unique CAE simulation tool combining many physical domains to address modeling of whole vehicles and of their powertrains. Having first focused on internal combustion engines with GT-POWER, GT rapidly dominated the market. The state-of-the-art software quickly expanded to simulate other systems such as thermal management, fluid systems, multi-body mechanics, electrical systems and fully integrated systems, giving rise to GT-SUITE, the company’s flagship product. Today, engineers around the globe use GT-SUITE to optimize products in many industries, including automotive, aerospace, industrial machinery, power generation and more. In recognition of his contributions, Dr. Morel was elected a member of the National Academy of Engineering (NAE), one of the highest professional honors given to an engineer.

founder & senior vice presidentSYED WAHIDUZZAMAN

Syed Wahiduzzaman is a founding member of Gamma Technologies where he currently serves as a Senior Vice President. He also leads a team of engineers for development of models and simulation tools for the exhaust gas aftertreatment systems (SCR, LNT, TWC, DOC, DPF, CPF, etc.), port-injection and fuel puddling phenomenon for the current generation engines, fuel cells, fuel reformers, chemical and process system simulation. His is responsible for development of advanced combustion models for low carbon fuels and eFuels GT-SUITE, as it relates towards the goal of achieving net-zero emissions. Other research activities include development of embeddable model calibrations and optimization technologies and productivity tools for GT-SUITE.

Syed finds taking long walks every day to analyze what he could have done better and generate new ideas for the emerging challenges.

founder & senior vice presidentRIFAT KERIBAR

Rifat Keribar is a co-founder of GT one of the original developers of the GT-SUITE software. He currently leads product and R&D teams focused on mechanics, NVH and tribology aspects of GT SUITE and their integration into GT multi-physics solutions. Rifat has more than 40 years of experience focusing on computer-aided engineering, simulation and R&D, primarily in Automotive Engineering, and a record of technical leadership and managerial positions. He is the author of more than 40 technical publications and has been recognized by several SAE and international awards for his work. Prior to GT, Rifat spent 4 years at GATX and 11 years at ITI/Ricardo-USA. Rifat holds a PhD degree in Mechanical Engineering from Northwestern University.

Rifat enjoys the best of what Chicago has to offer including the lakefront where he bikes and takes long walks, as well as his extended family. Among his enjoyable challenges outside work is the uphill battle to maintain his cool granddad status.
