UW student wins mathematics competition, named Putnam Fellow

UW News

Last month stadiums reverberated as students on the UW’s basketball team made it to the Sweet Sixteen round of the National Collegiate Athletic Association tournament. Meanwhile, over spring break another UW undergraduate quietly claimed the top prize in U.S. collegiate mathematics. William Johnson, who is majoring in mathematics and computer science, was named a Putnam Fellow, placing among the top five out of more than 4,000 students who competed this year.

While this competition allows no spectators, winning the Putnam is no less a feat than bringing home the NCAA title — especially when it’s an upset.

“Just as Duke, Kansas, and Kentucky always seem to dominate in basketball, the Putnam Fellowships have been ‘owned’ by Harvard, MIT and Cal Tech. It’s great to have a Husky join them,” wrote President Mark Emmert. “Our math department is truly remarkable in working with our students, and a real point of pride for us.”

The William Lowell Putnam Mathematical Competition is held each December by the Mathematical Association of America. The competition began in 1938, and is open to undergraduate students in the United States and Canada. The UW team had a strong finish last year (see our story here), but this is the first time a UW student has been named a Putnam Fellow.

Johnson grew up in the Seattle area and attended Kenmore’s Inglemoor High School. Last year he placed sixth overall in the Putnam, just two points away from being among the winners. He was recently named the UW’s Junior Medalist for earning the highest overall academic record for his class. This year he wins $2,500 and the honor of being named a Fellow, a distinction that will follow him through his career.

The contest is the most prestigious in U.S. mathematics circles. When mathematician Jonathan Nash, subject of the book and movie A Beautiful Mind, would first meet other mathematicians he reportedly would ask whether they had taken the Putnam and how they placed.

“This is huge,” said Selim Tuncel, chair of the mathematics department, noting that the list of previous winners includes many of the top names in the field. “Will’s achievement is a combination of amazing talent and excellent mentoring on the part of my colleagues.”

The UW team has been coached for the past two years by Ioana Dumitriu, a UW assistant professor of mathematics who in 1996 was the first woman to be named a Putnam Fellow, and Julia Pevtsova, also a UW assistant professor of mathematics, who was a silver medalist in the International Mathematical Olympiad.

“I am very, very proud of Will,” Dumitriu said. “For me, it’s a matter of huge pride to have a Putnam Fellow that I helped train.”

The coaches emphasize that they cannot take credit for Johnson’s performance.

“No amount of coaching could get him there unless he was willing to put in the work and unless he had this special talent to begin with,” Dumitriu said. “It’s kind of like athletes. There’s a tremendous amount of work that has to be put in, on top of a very good natural ability.”

And, like athletes, a winning score requires focus and stamina on game day. The Putnam is a six-hour contest. Competitors are given one set of problems in the morning and another in the afternoon. They must submit fully written-out proofs to get full credit. Of a possible 120 points, the average competitor scores 1 or 2. (Johnson scored around 100.)

During fall quarter Dumitriu and Pevtsova co-taught Math 480a, The Art of Problem Solving, which prepares students to write the Putnam (students in the course are not required to enter the contest). Pevtsova and Dumitriu also hosted weekly evening Putnam practice sessions that were attended by about 12 regulars and as many as 30 students.

This year 19 UW students wrote the Putnam. Four others placed in the top 500: Yisong Song, a freshman in pre-sciences, Steven Rutherford, a freshman in computer engineering and Keyun Tong, a senior in computer science and Nate Bottman, a senior in Russian and mathematics, who both placed in the top 500 last year.

In addition to the coaching, Johnson credits his success to his religious beliefs, parents who encouraged an interest in mathematics from an early age, good math teachers, and two years of participation in the Mathematical Olympiad Summer Program in Nebraska.

None of Johnson’s teachers was surprised to learn of his win.

“Will will be famous. I don’t know what he will choose to do. It doesn’t matter. He will add originality and depth to anything he tackles,” wrote Jim Morrow, a UW professor of mathematics and one of the teachers Johnson singled out as an influence.

And while Johnson excels in theorems and proofs, he also shows interest in applied problems. About a year ago Johnson approached Richard Ladner, UW professor of computer science and engineering, to help with his mobile accessibility research because he wanted to work on a project that could have a positive impact on people.

On his own initiative Johnson created a program that uses the vibration of an Android phone to transmit Braille through the touch screen. Johnson’s tool, dubbed V-Braille, has been tested by members of the local deaf-blind community.

“I have shown his V-Braille to colleagues around the country who have told me that V-Braille is ‘brilliant,’ ‘stunning,’ and ‘you should patent it,'” Ladner writes. He says he has seldom met a student “who has such prodigious talent, works hard, and is so creative.”

The other four Putnam Fellows this year hailed from Harvard, Yale and MIT. Though Johnson probably could have had his pick of these, he chose to attend the UW.

“I liked the campus, and I like the state of Washington, where I grew up,” said Johnson, whose tuition was paid through the Washington Scholars program.

Johnson has at least one more year of study at the UW. After graduating he is considering working in computer programming or pursuing a graduate degree in mathematics.
