American engineering prodigy Nathan Thomas has made history after being officially recognised by Guinness World Records as the world’s youngest male professor, achieving the feat at just 18 years and 346 days old. His accomplishment ended a record that had stood for more than 306 years, making him one of the youngest academics ever appointed to teach at the university level.

Thomas began teaching “C for Engineers” (COP 2270) at Miami Dade College in Florida, where he instructs undergraduate students in computer programming and engineering concepts. Despite being close in age to many of his students, he has earned praise for his expertise, professionalism and ability to simplify complex technical concepts.
His academic journey began remarkably early. At just 10 years old, Thomas enrolled at Miami Dade College through a dual-enrolment programme before transferring to Florida International University at the age of 14. By 18, he had completed both a Bachelor’s Degree and a Master’s Degree in Electrical Engineering, graduating with honours.
According to Guinness World Records, Thomas broke the long-standing record previously held by Scottish mathematician Colin Maclaurin, who became a professor at the age of 19 in 1717. Thomas also came within just 16 days of matching the overall record for the world’s youngest professor, held by Alia Sabur, who became the world’s youngest female professor in 2008 at the age of 18 years and 362 days.
Reflecting on his achievement, Thomas said age has never been a barrier to teaching.
“Once you’re in that setting, everyone’s there for the same reason, which is to learn. Age doesn’t really factor into that. I just focus on trying to do my job well and helping students in whatever way I can,” he said.
Thomas attributed his passion for engineering to his parents, both of whom are engineers. He explained that mathematics was the subject that naturally appealed to him from an early age and inspired his interest in science, technology, engineering and mathematics (STEM).
Beyond teaching, Thomas is continuing his education. He is currently pursuing a Juris Doctor (JD) degree at the University of Miami School of Law, with plans to specialise in intellectual property law, particularly in areas related to science, engineering and emerging technologies.
Despite his extraordinary achievements, Thomas says he enjoys many activities common among young adults, including basketball, tennis, golf and playing the piano. He also encouraged young people not to compare their journeys with others but to remain focused on their personal goals.
“Everyone’s path looks different, even if the goal looks similar from the outside. It’s better to figure out what actually works for you and stick with it. The results might not show up right away, but they come with time if you keep showing up and putting in the work,” he said.
Thomas’s achievement has drawn global attention as an inspiring example of academic excellence, lifelong learning and the possibilities that dedication and early exposure to education can create. Educators say his story demonstrates that age is no barrier to knowledge, innovation and leadership in higher education.
