Is a research scientist at INSERM (French National Institute of Health and Medical Research), working within the BioTis Unit (UMR U1026) at the University of Bordeaux. He specializes in tissue engineering applied to cardiovascular medicine. His research focuses on the development of next-generation vascular grafts and biological heart valves, entirely produced from human cell-assembled extracellular matrices (CAMs). By combining innovative biofabrication techniques, advanced cell culture, and biological textile technologies, Dr. Kawecki aims to design fully biological, implantable devices free of synthetic materials or chemical treatments. These solutions are designed to improve patient outcomes—particularly in pediatric cardiovascular surgery—by offering implants that integrate better with the host tissue and adapt as the body grows. In 2024, he was awarded the FC3R Research Prize for his work, which also includes the preclinical evaluation of these devices through in vitro, in silico, and animal models, with the ultimate goal of clinical translation.
