Former NFL player John Urschel makes breakthrough in mathematics research

Former Baltimore Ravens offensive lineman John Urschel, now an MIT mathematics professor, is gaining attention for new research on random matrices

Former Baltimore Ravens offensive lineman John Urschel traded football for mathematics when he retired from the NFL in 2017. Nearly a decade later, the 35-year-old MIT professor has accomplished something that mathematicians have been trying to figure out for years.

According to The Washington Post, Urschel recently made a significant breakthrough in mathematical research, solving a longstanding problem involving an algorithm used to solve complex equations.

His findings were published in a research paper titled “On the Growth Factor of Random Matrices,” which began attracting widespread attention after fellow mathematician Ethan Epperly shared the work on social media.

The research centers on Gaussian elimination, a mathematical method used to solve systems of equations. Although the method has been used successfully countless times, researchers have long sought a better understanding of its reliability.

Urschel’s work provides new mathematical evidence about the method’s stability, helping answer a question that had puzzled researchers for decades.

Ethan Epperly, a researcher at the University of California, Berkeley, told The Washington Post that the problem had been a longstanding topic of discussion among mathematicians.

For Urschel, the discovery reflects a fascination with understanding not just whether something works, but why.

“It just seems so interesting that the most fundamental algorithm we have in the field, we do not fully understand,” Urschel told The Washington Post.

Long before his latest achievement, Urschel was balancing his love of mathematics with a professional football career.

He began taking graduate-level mathematics courses while attending Penn State and continued his academic studies after the Baltimore Ravens selected him in the fifth round of the 2014 NFL Draft.

Even while playing professional football, Urschel took classes at MIT and published academic research. However, concerns about brain injuries, including a serious concussion he sustained in 2015, contributed to his decision to retire from the NFL two years later.

He subsequently earned his doctorate in mathematics at MIT, where he now teaches and supervises doctoral students.

In a 2019 interview with The Washington Post, Urschel expressed his hope that one day people would recognize him primarily for his academic accomplishments rather than his football career.

These days, he’s getting his wish.

Urschel told the publication that he enjoys the relative anonymity of academic life, where his former NFL career rarely comes up.

Still, his students occasionally remind him of his football past. According to The Washington Post, a group of students once showed up to their final exam wearing his Baltimore Ravens jersey.

For a man who once made his living protecting quarterbacks, Urschel has found a different kind of success tackling some of mathematics’ toughest questions.
