While pursuing his bachelor’s degree at Universidad Pontificia Comillas, Saúl focused on mechanical engineering, patents, and medical devices. He volunteered with UNESCO in Jeju-do (South Korea), helping to restore cultural heritage sites, and also designed and patented a telescopic catheter intended to access hard-to-reach areas of the body. While completing his master’s degree at the University of Navarra, he specialized in biomechanics and medical devices, analyzing the viability of a new medical device for large intestine analysis. He traveled to Düsseldorf, Germany, to source providers for building the final design of the device. Saúl has conducted research in dental biomechanics for eight years and will continue to do so, researching current endodontic procedures and the methods of testing medical procedures, implants, and treatments. While doing so, he has designed several medical devices and works to get these ideas to different medical companies. He completed his Ph.D. in 2025, focusing on how dental treatments affect the long-term aging and durability of teeth. Together with his research partners, he found that certain commonly used treatments may be harmful to patients over time. Saúl now works as a professor and researcher, teaching future generations of engineers while investigating the causes of dental failure. He is fluent in Spanish and English, proficient in French, and has basic knowledge of Japanese.
