G Cadogan

G Cadogan

G is a Boston native who recently graduated from Emerson College with a BFA in theatre education. G is an interdisciplinary artist and educator with passions for social justice and teaching. What excites them about teaching is that they get to bring these passions directly into their work as an educator.The medium of theatre already encourages collaboration, listening, and empathy and G emphasizes the importance of these traits in their classroom. When working with students one on one, G comes to notice and appreciate each student’s unique characteristics, which is why they do not treat all of their students the same. G always welcomes new ideas and suggestions to anything that is being covered in the classroom to offer students the opportunity to see their ideas in action. When they are not teaching, G enjoys reading, playmaking, or just chilling out and watching Netflix with their roommates.This is the end of the biography but not the person!

Chris Fountaine

Chris Fountaine

Chris’s love for math began when he took Algebra 1 and his curiosity led him to browse calculus books three years too soon. Feeling eager to know what foreign symbols meant, he took calculus, often tutoring it to small groups and friends. He received his MS degree in mathematics from Tufts University where he focused on the three major cornerstones of contemporary mathematics: analysis, abstract algebra, and geometry/topology. Before Tufts, he completed his undergraduate education at Saint Anselm College, graduating magna cum laude with an honors BA in mathematics and classical languages. In college, he was also formally admitted as a special student to MIT where he took advantage of challenging abstract math lectures and attended the linguistics colloquia through the department of philosophy and linguistics. Since 2014, he has been a private math and SAT tutor in the greater Boston area, often tutoring multivariable calculus and linear algebra to high school students enrolled part-time at Harvard. When he’s not tutoring, he’s hiking, exercising, cooking new recipes, watching documentaries, or buying more plants he doesn’t have room for.

Asa Frank

Asa Frank

Asa graduated from Carnegie Mellon University, where he majored in computer science and minored in discrete math and logic. He also worked as a teaching assistant, mostly for introductory programming and math classes and loved helping inquisitive underclassmen explore new subjects. The most accurate piece of feedback he received from a student said simply, "little kid." After graduating, he became a software engineer, known around the office for playing Tetris, pulling pranks, and sleeping under desks. He sometimes even wrote code. Feeling unfulfilled but remembering his passion for teaching, he left to join AoPS. He's usually found in his native habitat of rock climbing gyms, screaming for more power and playing Tetris between climbs. He can't tie a tie, but he can do a one-finger, one-arm pull-up, which isn't as useful, but at least it's cool.

Ariel Wertheim

Ariel Wertheim

Since graduating Dartmouth College, Ariel has explored passions for science research and education. While he has enjoyed his work at North Dakota State University and the Volcani Center on sustainable agriculture and plant-microbe interactions, he has found his most rewarding work has been with 11-13 year old students in mainstream classroom, special education, and supplemental religious school settings. Ariel enjoys cooking, hiking, reading, and a good math puzzle. Ariel considers his greatest achievements to be "persuading" students to enjoy a subject they previously disliked. His favorite part of teaching is seeing the "lightbulb moment" when a child solves a problem they'd worked hard on.

Huayu Xiong

"General coaching classes at many academic training centers stress repetition of the concept until a student grasps it thoroughly. At AoPS Academy, they go far beyond repetition. Their highly qualified instructors do a great job at teaching fundamental concepts to students at much greater depth, and challenge them to walk that extra mile by presenting them with more complex problems to solve. It provides a great learning experience in a friendly, fun, yet competitive and challenging environment. They provide their students with a combination of excellent instructional curriculum along with amazing online tools. AoPS Academy also encourages students to take part in various competitions. Overall they do an incredible job imparting a deep knowledge of both math and language arts to all of their students, and AoPS Academy sets them on a path towards their career goals. We are happy to be part of AoPS Academy family!"
