He pursued a PhD in Chemical Engineering, specializing in polymer hydrogenation, from IIT Madras. His doctoral research focused on the "Hydrogenation of Polymers," where he became an expert in catalyst synthesis and characterization. This foundational knowledge set the stage for his later groundbreaking work in polymer modification and catalytic hydrogenation.

Professional Endeavors

He began his illustrious career at the Indian Space Research Organization (ISRO) on January 5, 2007. He currently serves as a Senior Scientist at SDSC-SHAR, Sriharikota, Andhra Pradesh. His role extends to being a senior quality executive, ensuring the high standards of ISRO's outputs. Simultaneously, he is a research scholar at IIT Madras, working in the Department of Chemical Engineering. His dual roles in academia and industry position him uniquely to bridge theoretical research and practical applications.

Contributions and Research Focus in Mechanical Engineering 

His research has significantly advanced the field of polymer hydrogenation. He successfully demonstrated the influence of various process parameters on the conversion rates in hydrogenation, specifically the synthesis of propellant-grade Hydroxyl-Terminated Polybutadiene (HTPB) into Hydrogenated Hydroxyl-Terminated Polybutadiene (HHTPB) using Pd-activated charcoal as a catalyst. This work is pivotal for the polymer industry as it enhances the stability and performance of polymers used in solid rocket propulsion.

Accolades and Recognition

His pioneering work in polymer hydrogenation has not gone unnoticed. He was honored with the Best Researcher Award for his exceptional contributions to the field. His patent on the "Process for Manufacture of Hydrogenated Hydroxyl-Terminated Polybutadiene (HHTPB) using Pd-Zr-supported on Activated Charcoal Catalyst" (Indian Patent Number: 537079) is a testament to his innovative spirit and technical expertise. This patent, granted on May 7, 2024, underscores his role as a leading researcher in catalytic hydrogenation.

Impact and Influence

His research has had a profound impact on the polymer industry. His work on hydrogenation catalysts has improved the efficiency and effectiveness of polymer hydrogenation processes. The advancements he introduced have paved the way for the development of more durable and high-performing polymers. His publications, such as those on the influence of isomer ratios of toluene diisocyanate on solid propellant behavior and the effects of process parameters and cure catalysis on HTPB-IPDI-based solid propellant behavior, have become essential references for researchers and professionals in the field.

Legacy and Future Contributions

As a senior scientist at ISRO and a research scholar at IIT Madras, he continues to push the boundaries of polymer modification and hydrogenation. His work not only contributes to the scientific community but also has practical applications in space exploration and defense. The quality control tool he developed to study the influence of aluminum powder variation at the premix level of propellant slurry is a prime example of his innovative approach to solving complex problems. Polymer hydrogenation is a critical process in the polymer industry that involves the addition of hydrogen to polymers to improve their properties and performance. This technique, often employing catalytic hydrogenation, modifies the polymer's chemical structure, resulting in enhanced stability, durability, and resistance to environmental factors.
