Most teenagers are preparing for their first year of college. Nathan Thomas was preparing to teach one.

The South Florida native has been recognized by Guinness World Records as the youngest male professor in history after joining the engineering faculty at Miami Dade College at just 18 years and 346 days old. His achievement ended a record that had remained untouched for more than 300 years.

The previous benchmark belonged to Scottish mathematician Colin Maclaurin, who became a university professor at age 19 in the early 18th century. Thomas also became the youngest professor overall in modern times, edging out the current female record holder, Alia Sabur, by just over two weeks.

Thomas started teaching the college’s C for Engineers programming course in August 2023. Many of the students sitting in his virtual classroom were nearly the same age as their instructor, but he says that quickly faded into the background once lessons began.

Rather than focusing on his age, Thomas concentrates on helping students understand difficult programming and engineering concepts. He believes commitment and a willingness to learn are far more important than the number of years someone has lived.

His rapid academic rise began long before he entered the classroom. At only 10 years old, Thomas enrolled at Miami Dade College through a dual-enrollment program. By age 14, he had transferred to Florida International University, where he completed both undergraduate and graduate degrees in electrical engineering with honors within four years.

Educators at Miami Dade College say Thomas brings more than impressive credentials to the classroom. School leaders have praised his ability to connect with students and serve as an example of what determination and academic excellence can accomplish.

Thomas credits much of his early interest in engineering to his upbringing. Raised in a family of engineers, he developed a love for mathematics at a young age and says his mother had a talent for explaining difficult ideas in ways that made them easier to understand. That early foundation sparked his lifelong interest in STEM subjects.

Although solving technical problems has always appealed to him, Thomas says teaching offers a different kind of reward. Seeing students finally understand a concept after struggling with it is one of the most satisfying parts of his job. He also believes every lesson he teaches deepens his own understanding because explaining complex material requires complete mastery of the subject.

Thomas isn’t slowing down after breaking a world record. While continuing to teach engineering courses online, he is studying at the University of Miami School of Law, where he expects to earn his Juris Doctor degree in 2028.

His long-term goal is to build a career in intellectual property law, combining his engineering background with legal expertise to help protect innovations in science and technology. He says the analytical thinking developed through engineering has given him a strong foundation for the challenges of law school.

At an age when many young adults are just beginning college, Nathan Thomas has already earned graduate degrees, set a Guinness World Record, and inspired students by proving that talent, discipline, and hard work can overcome expectations.
