To inspire girls through the beauty of mathematics and encourage them to confidently pursue STEM careers
To provide articles and resources to spark analytical, creative thought, and to showcase the creativity and accessibility of math
To build a supportive, passionate global community around mathematics
GLeaM's founder, Catherine Cossaboom, a current senior in high school, is the sole creator of all GLeaM events, articles, and curricula. She has been extremely passionate about math from an early age. She is a member of Georgia's state math team, Georgia ARML, an alum of the Math Prize for Girls competition at MIT, and a successful participant in the MATHCOUNTS and AMC/AIME competitions. She is a three-year captain of the Chamblee High School Math Team and has led the team to back-to-back 5A State Championships. She attended the Georgia Governor's Honors Program in 2019, as a math major, and the prestigious Ross Mathematics Program for number theory studies in 2020. She has also completed the entire three-year curriculum of Art of Problem Solving's Worldwide Online Olympiad Training program. In July 2020, she became a Problem Writer for inteGIRLS, a dynamic girl-led nonprofit hosting math competitions and puzzle hunts across 15 international chapters.
GLeaM focuses on fascinating fields of math outside the typical K-12 curriculum, such as number theory, graph theory, and combinatorics, as well as prep for middle and high school math competitions, including AMC and MATHCOUNTS.
In college, Catherine plans to pursue a double major in Applied Math (with a focus on Mathematical Neuroscience) and Scientific Journalism, combining problem-solving and storytelling to transform the future.
Catherine sees math as empowering and life-affirming, and she is motivated to share this philosophy through mentoring and connecting with members of GLeaM.
Note: This site is geared toward girls, and the majority of members identify as female or non-binary; however, everyone, regardless of gender identity, may join GLeaM as long as they are respectful and support the community. We welcome all members!
GLeaM's website guides members through a variety of resources, including competition-related websites,
listings of opportunities around the world, and links to exciting topics in various fields of math. This creates an immersive experience for members and helps them to grow their knowledge and passion for STEM fields.

Frequent articles are uploaded, discussing eye-opening topics in math, as well as tips as to how to improve your math game, including prep for local and national math competitions.
A friendly server accessible for comments allows us to discuss the material and provides enrichment and puzzles for all types of problem-solvers.

AN INNOVATIVE COMMUNITY
Each member of the GLeaM community has access to the forum, where they can post ideas, questions, stories, and anything they want to discuss with the community. In this way, the founder can also gather feedback to better curb the program to members and their interests.
You can sign up to become a member by clicking "Sign Up/Log In" in the upper right-hand corner.

Occasional scheduled events will occur, where we can delve further into an area of interest or into prep for competitions.
Event information will be posted well in advance to the forum.
Members are also always welcome to contact the founder for any advice or to set up a personal Zoom mentorship session.

OUR LOGO STORY
The great mathematician Maryam Mirzakhani's daughter often described her work as "painting," as she crouched on the floor drawing on large sheets of paper. Mirzakhani was the first woman to win the Fields Medal, an illustrious award that is often equated with the Nobel Prize for math. She was a major advocate for women in mathematics, and in 2017, she died from breast cancer at age 40. The paintbrush is a symbol of Mirzakhani, but also of the beauty of mathematics, closely intertwined with art in the way ideas transition marvelously into one another. Around the paintbrush is a fractal, the Sierpinski triangle, one of the most magnificent aspects of math, reminding us to pursue seemingly impossible dreams in surprising fractional dimensions.
“Pure mathematics is, in its way, the poetry of logical ideas.”
