Since PUMaC is a student-run competition, it relies heavily on the effort given by its volunteers. The following is the list of people who are currently involved in making PUMaC 2018 a success.


William Jiao

William is a junior and mathematics major from West-Windsor Plainsboro, NJ. He has participated in one too many math competitions, and has decided to organize them instead. Aside from doing math and organizing PUMaC, William enjoys eating sushi, throwing cards, and alternating between pulling all-nighters and sleeping past noon.





Jacob Wachspress
Competitions Coordinator

Jacob is a junior from Pennsylvania studying math.  He has been a participant and an organizer for PUMaC three times.  He enjoys dark chocolate, Latin pop, jogging in green places, baseball and fantasy football.


Mikako Inaba
Logistics Director

Mikako is a sophomore from Bergen County, NJ potentially majoring in computer science. She has enjoyed competing in math competitions including PUMaC in the past and looks forward to helping organize it. She is also part of the synchronized figure skating team and continues her high school cross country career in the running club.


Juneseo Lee
Communications Director

June is a sophomore from New Jersey studying math. He is working as a problem writer this year after being assistant-director last year and a participant in previous years. He enjoys playing guitar, ultimate frisbee, and table tennis.



Sam Mathers
Live Round Director

Sam is a sophomore from Morgantown, West Virginia. He intends on majoring in math and, thus did quite a few math competitions in high school (although unfortunately never PUMaC). In the few hours he has not working on assignments or procrastinating working on assignments, Sam enjoys playing table tennis, reading Russian novels, clicking on links in Wikipedia articles, and reminding people that West Virginia is indeed a distinct state from Virginia.


Karen Ying
Volunteer Coordinator

Karen is a sophomore and probable ORFE (applied math) major from Belmont, MA. She participated in various math camps and competitions in high school and is super pumped to help run PUMaC this year. Aside from staying up way too late to finish psets, she spends her time playing Ultimate Frisbee, trying to get good at pool, and out-eating lax bros at meals. 


Nathan Bergman
Problem Czar

Nathan is a sophomore and prospective math major from Mesa, Arizona. He participated in many math competitions in high school and is happy to help out now that he's in college. In addition to math, he enjoys playing board games, creating riddles, and complaining about how hot Arizona gets in the summer.



Jackson Blitz
Problem Czar

Jackson is a sophomore and prospective math major from Fort Lauderdale, Florida. He participated in a lot of math competitions and the like in high school. He is excited to be on the opposite side, writing problems no one will ever get. He likes rap.



Zack Stier
Problem Czar Emeritus

Zack is a junior math major from Bergen County, New Jersey. He did lots of math in high school, and having competed in PUMaC four times he is excited to return to the team that makes it happen; this year, in addition to writing problems he'll also be working on the Math Bowl. In his free time, Zack plays basketball, watches classic films, and makes references to those films that his friends don’t get. You can find him around campus wearing shorts and being tall.



Eric Neyman
Director Emeritus/Problem Writer

Eric is a senior studying math and theoretical computer science. After directing PUMaC last year, he decided to return to his roots as a problem writer. His interests include puzzles, board games, and rationality.



David Song
Mini-Events Czar

David is a sophomore computer science major from Ridgewood, New Jersey. After determining that writing good math questions isn't easy, he switched over to running mini-events instead. When he's not jamming out to K-pop, you can find him watching football or playing Pokémon GO.

Davey FitzPatrick
Puzzle Hunt Director

Davey is a sophomore from Rochester, New York and a prospective math major. He never competed in PUMAC, but he did go to ARML, which is the same thing except it’s run by actual adults and it has a different acronym. Besides doing math, he enjoys listening to early Genesis and pretending he can play the piano. He has very strong opinions about metaphysics and the sleeping beauty problem.




Alec Leng
Tech Team Lead

Alec is a sophomore from Portland, Oregon, who will major in math with probability around 99%. When he's not busy doing work, he primarily enjoys watching anime, doing math and playing games, but concedes that programming isn't too bad either.


Geoffrey Mon
Tech Team

Geoffrey is a sophomore computer science major from Athens, Georgia who does not have a southern accent. When not procrastinating, he can be found scavenging ramen, losing quiz bowl buzzer races, or napping.


Simon Park
Tech Team

Simon is a second year student from Seoul, South Korea. He has never participated in PUMaC, but after proctoring last year, he decided that he wanted to help out. If you see a person on campus wearing a pink/orange hoodie, it’s probably him.
