Inspired by his childhood experiences and a profound desire to make a difference, Gabriel pursued a medical career, graduating in Medicine in 2014. Towards the end of medical school, he encountered the burgeoning field of tissue engineering, immediately grasping its immense potential to create bioartificial tissues and organs for future transplantation. This revelation prompted a pivotal decision: he paused his medical career to dedicate himself to a Ph.D. in this transformative field, recognizing it as a direct pathway to addressing the organ shortage crisis. Upon completing his Ph.D. in 2019, his involvement with tissue engineering had deepened to such an extent that he made the arduous choice to forego traditional medical practice. Instead, he committed himself entirely to research and development, driven by the singular goal of translating this revolutionary technology from the lab to patients. He understood that pursuing both simultaneously was untenable, and he feared that if he returned to clinical practice, his unique vision and concentrated drive for tissue engineering might not be sustained by others. Initially, he contemplated pursuing these goals within academia, which led him to establish a lab in Brazil. However, he quickly discerned that the objectives and incentives prevalent within university settings—often focused on theoretical research rather than rapid commercialization—were not aligned with the swift, impactful translation of science into practical applications that he envisioned. This realization solidified his conviction that a dedicated company was the optimal vehicle for his mission, leading directly to the founding of TissueLabs.
