Lenhard Ng

He was included in the 2019 class of fellows of the American Mathematical Society "for contributions to Floer homology and low-dimensional topology and service to the mathematical community".

Lenhard earned his B.A. summa cum laude in Mathematics and Physics from Harvard University in three years and his Ph.D. in Mathematics from the Massachusetts Institute of Technology in 2001.

Lenhard Ng (born 1976, United States) is an American mathematician, working primarily on symplectic geometry. Ng is a professor of mathematics at Duke University.

At the age of 12, he began taking courses (on a part-time basis) at the University of North Carolina, Chapel Hill. He was not yet 13 when he won the Written Round of the MATHCOUNTS competition. At the age of 14, he participated in the International Mathematical Olympiad and earned a Silver medal. He participated in this competition for the next two years and earned Gold medals. He entered college (Harvard University) full-time at the age of 16 and majored in Mathematics and Physics, graduating summa cum laude in three years. He competed in the William Lowell Putnam Mathematical Competition while at Harvard University and was a three-time fellow, one of only 18 people to have achieved this feat since 1938. The first time he became a Putnam Fellow was at the age of 16, making him one of only 6 people (the 5 others being Arthur Rubin, Noam Elkies, Don Zagier, David Ash and John Tillinghast) in the history of the competition to have achieved this feat.
