Our startup is the result of extensive research on polymer composites conducted during the founder's PhD in the UK, funded by the French industrial partner Technical Centre of Mechanical Industries (CETIM). It also includes a collaborative research project on multiaxial fatigue conducted with Deutsche Bahn Engineering & Consultants in Germany and the University of Parma in Italy.

I was the Co-Chair of the 12th International Conference on Residual Stresses, which was held in the USA on October 2025. I wholeheartedly endorse him and his business proposal. Based on his impressive accomplishments, I not only selected Praveen to give an invited talk, but I also asked him to organize a symposium on composites.

The business proposition that Praveen has put forward in his startup is grounded in robust scientific principles and technological innovation in composites manufacturing. Given his deep understanding of materials science and structural engineering, his venture has the potential to disrupt the market and bring meaningful advancements in the field.
PROF. ANDREA SPAGNOLI, ITALY
Professor - University of Parma, Named in the 2023 Stanford University-Elsevier list of the World’s Top 2% Scientists
Praveen was the key point in developing the collaboration between the Parma University, DB Engineering and Consulting GmbH - Germany and National Institute of Technology Patna - India. This collaborative work involved researching on the applicability of critical plane approach based fatigue assessment for the remaining life of structures. Praveen demonstrated the ability to work independently with inspiration and zeal as well as effectively leading the research work and well co-ordinated between the co-authors.
PROF. S S MISHRA, INDIA
Professor - National Institute of Technology Patna - India
Have known Praveen as an exceptionally motivated and independent researcher with deep expertise in structural integrity and advanced finite element modeling. His ability to combine rigorous engineering analysis with innovative simulation approaches is remarkable. I am confident that his venture on Digital Twinning of Composite Structures will set new benchmarks in predictive modeling and structural health monitoring.
