Tay was born in Russia, grew up in Seattle, and is currently studying Applied Mathematics and Aerospace Engineering at the University of California, Davis. From a young age, she has been fascinated with math, and she considers herself lucky that her family encouraged her growth in that area - her grandma, a Doctor of Theoretical Physics at Moscow State University, was especially supportive of this pursuit of knowledge, and it was not uncommon for her to write up extra math problems for Tay to solve during school breaks and summer holidays.

Tay attributes the success she's had in the mathematical field to all the wonderful teachers she had in middle and high school. She believes that a good teacher - one that meets the students where they're at and helps them understand the "why’s” and "how's'' of mathematical processes, rather than just focusing on rote memorization of formulas - is one of the most important factors in getting a kid to like math. Tay hopes to be that teacher for all the kids she teaches at EMC.

In her free time, Tay enjoys reading science-fiction novels and improving her skills as a digital artist. She is also part of a group of friends that meet weekly to play Dungeons & Dragons - their current campaign has been running for just over a year now!

Ever since Matt was a kid, he always found the creativity involved in math to be the real fascination. Memorizing formulas may be boring, but problems that make you think, that make you look at the problem in a new light, that rearrange the pieces to turn the inscrutable into the obvious are where the joy of math lies. He would often get bored in school by the meaningless repetition and annoyance of plugging and chugging through endless formulas. It would seem to suck out whatever fun was left in the subject, especially with the dead seriousness of the class. 

Teaching gives Matt a chance to try and make a class where the kids have a fun time, want to learn the math, and have interesting problems to solve. 

Matt is currently a junior at Athens Academy in Georgia, where he is President of Math Club. In his free time, he enjoys practicing guitar and reading murder mysteries.
