mathematician university professor
John Pardon grew up in Durham, North Carolina, in an academically inclined family. His father, William Pardon, is a mathematics professor at Duke University, which influenced John’s early exposure to advanced mathematics. From a young age, Pardon displayed exceptional intellectual talent, particularly in problem-solving and mathematical theory.
Pardon attended Stanford University initially before transferring to Princeton University, where he graduated as valedictorian in 2011. During his undergraduate years at Princeton, he took advanced graduate-level mathematics courses early and tackled significant open problems. He earned his Ph.D. in mathematics from Princeton University in 2015, supervised by Yakov Eliashberg. Aside from mathematics, Pardon engaged in a Chinese-language immersion program and represented Princeton in an international debate competition broadcast on Chinese television.
John Pardon’s career is marked by early and sustained academic excellence. As a high school student at Durham Academy, he attended classes at Duke University and was a three-time gold medalist at the International Olympiad in Informatics (2005, 2006, 2007). In 2007, he placed second in the Intel Science Talent Search competition by generalizing the carpenter’s rule problem for polygons to rectifiable curves, proving that every rectifiable Jordan curve can be deformed continuously into a convex curve without length change or point proximity reduction. This research was published in the Transactions of the American Mathematical Society in 2009.
At Princeton, Pardon solved a longstanding problem in knot theory, posed by Mikhail Gromov in 1983, regarding the boundedness of the stretch factor of knots embedded in three-dimensional space. Pardon demonstrated that certain torus knots can have arbitrarily large stretch factors, disproving the hypothesis. His solution was published in the Annals of Mathematics in 2011.
Following his Ph.D., Pardon returned to Stanford University as an assistant professor. In 2015, he was appointed a Clay Research Fellow for a five-year term. Among his other notable achievements is solving the three-dimensional case of the Hilbert–Smith conjecture.
Solved Gromov’s 1983 problem on knot distortion, earning the 2012 Morgan Prize for outstanding undergraduate research.
Published his groundbreaking knot theory proof in the Annals of Mathematics (2011).
Two-time winner of the Princeton Sinfonia concerto competition as a cellist.
Appointed Clay Research Fellow (2015).
Made significant contributions to topology, geometry, and mathematical conjectures such as Hilbert–Smith.
Pardon is recognized for his intellectual rigor, creativity in problem-solving, and commitment to academic excellence. His participation in competitive debate and music highlights a well-rounded and disciplined personality.
John Pardon is the son of William Pardon, mathematics professor at Duke University.
