elementary school, he has been a participant in math competitions like MathCounts and the AMCs.
In high school, he has had the honor of representing TJ at math contests across the nation and
wants to provide the opportunity for more people to discover the allure of math often absent in
traditional curriculums. To that effect, he serves as the statistician of TJ’s Varsity Math Team
and is in his second year of co-teaching a middle school math club. Dong especially enjoys seeing
each student in the class energetically display their unique personalities as they learn novel and
unexpected mathematical concepts.
“To a lot of people, math is something mechanical that’s meant to
be memorized for a test and forgotten shortly afterwards. But it’s really a way of thinking that’s
objective and carefully reasoned out, while still actively involving a creative mindset,” Dong said.
Besides math, Dong enjoys working on computer science and more recently has become engaged in TJ’s
Urban Dance Movement. He attributes his success in the former, such as qualifying for the Platinum
division of the USA Computing Olympiad, to the fundamental reasoning skills he acquired from math.
Dong favors Python and Java, but he is also familiar with C++, C, and LaTeX typesetting. Dong recognizes
that he has had many opportunities afforded to him in his development mathematically and personally,
and wants to provide service to his local community in return through Illumony. In the future, he
wants to study mathematics and machine learning and additionally volunteer his services to the
competition math world he has enjoyed for so long.

Amy Chen is a Senior at TJHSST who hopes to increase young women’s love for STEM. In elementary school, she was a part of a Girls in STEM outreach program; the program conducted fun experiments, like the rocket lab, which contributed to why she chose to attend TJ in the first place. Now, almost a decade later, Amy hopes to share these same experiences with a new generation of young women. At TJ, Amy is the Engineering President for WISE, a volunteer program that conducts labs for fourth-grade girls from Weyanoke Elementary School. The program not only allows young girls to become interested in science but also exposes these young girls to female role models whom they will look up to as they grow up. Amy believes that one important contributor to the lack of women in STEM is the idea that STEM is for boys, not girls. At Illumony, Amy hopes to create and conduct programs and experiments for young women to create a welcoming environment for girls interested in STEM. These programs will provide young girls the ability to gain new knowledge of STEM, ranging from Scratch coding to candy DNA helices, and gain new long-lasting friendships with other people who share the same interests. Outside of STEM outreach, she is a member of TJ’s Policy Debate Team and a member of TJ’s Varsity Swim Team. These latter experiences, especially the debate team, have accelerated her personal growth through the learning of social inequity regarding women’s education, a meaningful message she hopes to share with others at Illumony.
