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 2019 a success.


Mikako Inaba

Mikako is a junior from Bergen County, NJ 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.


Alec Leng

Alec is a junior from Portland, Oregon, majoring in East Asian Studies. 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.


Jacob Wachspress
Director Emeritus/Competitions Coordinator

Jacob is a senior 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.


Juneseo Lee
Logistics Director

June is a junior 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 junior 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.


Michael Gintz
Problem Czar

Michael is a sophomore from Peoria, Arizona majoring in math. Having competed in PUMaC in high school and failed miserably, he is excited about being able to give high-schoolers that same experience. He's also a fan of linguistics, coding, and puzzles of all shapes, sizes, flavors, and collective nouns.


Marko Medvedev
Problem Czar

Marko is a sophomore from Serbia majoring in math. He enjoyed participating in many math competitions during high school. He also had a lot of fun being a problem writer for PUMaC last year and is looking forward to writing the Power round this year. When he’s not doing work, he enjoys playing basketball, reading superhero comics and playing games.


Byron Chin
Mini-Events Director

Byron is a junior from West Windsor, NJ majoring in math. When he is not busy doing work, he enjoys playing golf, watching TV, and solving Rubik’s cube puzzles.


Davey FitzPatrick
Puzzle Hunt Director

Davey is a junior 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.
