Guinness World Records crowns Nathan Thomas youngest male professor at 18

American engineer and educator, Nathan Thomas, has officially been certified by Guinness World Records as the youngest male professor globally, breaking a record that stood for over three centuries. The announcement, confirmed by our correspondent on Wednesday, revealed that Guinness World Records published the achievement on its website on July 23, 2026. Thomas secured this remarkable feat when he commenced his teaching role at Miami Dade College in August 2023, at the age of 18 years and 346 days.

Upon entering his first class to teach COP 2270: C for Engineers, Thomas found many of his students were teenagers, much like himself. Born on September 9, 2004, Thomas surpassed Scottish mathematician Colin Maclaurin, who became a professor at 19 in 1717, holding the record for an impressive 306 years. Furthermore, Thomas was 16 days younger than American engineer Alia Sabur, who became the world’s youngest female professor in 2008.

Here are nine key details about Nathan Thomas:

1. **World’s Youngest Male Professor at 18:** Thomas made history by joining Miami Dade College's faculty in August 2023, aged 18 years and 346 days, shattering a 306-year-old record, according to Guinness World Records.

2. **Teaching Peers:** When Thomas first stepped into the classroom, many of his students were close to his own age. Despite this, he stated that age never posed a barrier, as everyone shared the common goal of learning. He remarked, “Once you’re in that setting, everyone’s there for the same reason, which is to learn. Age doesn’t really factor into that.” He added, “I just focus on trying to do my job well and helping students in whatever way I can. If someone’s willing to put in the effort, that’s really all that matters to me.”

3. **Early College Enrollment:** Thomas embarked on his academic journey exceptionally early, enrolling in Miami Dade College at age 10 through a dual-enrollment program. He later transferred to Florida International University when he was 14.

4. **Degrees Before 19:** By his 18th birthday, Thomas had already earned both his bachelor’s and master’s degrees in Electrical Engineering, graduating with honours from both programs. While many of his age group were just preparing for university, he had already completed postgraduate studies.

5. **Engineering Family Background:** Thomas revealed that his passion for science, technology, engineering, and mathematics naturally developed, as both his parents are engineers. He specifically acknowledged his mother for her ability to simplify complex concepts, stating, “My mom had a way of making things feel simple even when they weren’t, and I think some of that stuck with me more than I realized at the time.”

6. **Learning Through Teaching:** Thomas believes that teaching deepens his own comprehension of a subject. He finds seeing students grasp challenging concepts to be one of the most fulfilling aspects of lecturing. He noted, “Teaching something forces you to understand it on a whole other level – so I end up learning just as much from it as the students do, if not more.”

7. **Pursuing Law:** After starting his teaching career, Thomas enrolled in a Juris Doctor degree program at the University of Miami School of Law. He intends to specialize in intellectual property law with a focus on STEM fields and is expected to complete his degree in 2028.

8. **Hobbies and Interests:** Beyond his academic pursuits, Thomas enjoys basketball, tennis, and golf. He is also a fan of the Boston Celtics and New England Patriots, plays classical piano, and enjoys music from Drake, EDM, and house genres.

9. **Embracing Individual Paths:** Thomas advocates for individuals to avoid comparing their progress with others, instead focusing on consistent self-improvement. He advised, “Everyone’s path looks different, even if the goal looks similar from the outside.” He continued, “It’s easy to fall into comparing your timeline to someone else’s, but really all that does is slow you down and get in your head.” He concluded, “In my opinion, it’s better to figure out what actually works for you and stick with it, even when it feels slow. The results might not show up right away, but I truly believe they come with time if you keep showing up and putting in the work.”

Thomas’s extraordinary accomplishment has garnered global attention, not only for eclipsing a 306-year-old record but also for demonstrating that profound academic excellence and a dedication to teaching can emerge at a remarkably young age.
