Shaun Wrinn

Shaun spent most afternoons as a young kid in the sparsely populated (and off-limits during school hours) second floor of his school's library as his mom finished her teacherly duties for the day. His love of words and teaching led him to get his master's degree in curriculum and instruction at his beloved University of Connecticut (Go Huskies!). Shaun helped to pioneer the International Baccalaureate program at his last school and was chosen by the class of 2021 as their faculty speaker at graduation. Shaun taught high school English and coached girls' basketball for ten years across the great state of CT and has seen former students excel in their academic and personal journeys--a feeling that cannot be replaced. After his time in CT, Shaun moved to Boston to go see about a girl. Shaun is excited to see where the road may lead in and out of the classroom. When not teaching, he dabbles as a Celtics Season Ticket Holder, halfway decent cook, great friend, music lover, and funny dude.

Alan Zhou

Alan Zhou

Alan grew up in Lexington (about five minutes from this campus, although it didn't exist at the time) and joined AoPS as a middle school student in 2007 when he was getting started in math competitions. Becoming part of an enthusiastic math-centered community of students was a large part of his life in middle and high school, and following high school, Alan earned a bachelor's degree in mathematics from the University of Cambridge and a master's degree from UCLA, focusing primarily on algebraic number theory. During these years, he found that what he enjoyed most in math was being able to share with younger peers the perhaps unexpected but deep connections between different areas (number theory has a lot of these!), and returning to AoPS as an instructor, he hopes to be able to convey how amazing these ideas are to new generations of students. Outside of mathematics, Alan enjoys soccer, racquet sports, real time strategy video games, light novels, and looking for good sashimi.

Our family regularly talks about AoPS. We try to think about how our life would be different without you all. What if my daughter hadn't learned to love math? What if she never experienced being pushed to her limits? Overcoming failure? She wouldn't be who she is. And she is AWESOME! A very proud mom here. We are so fortunate that we found AoPS Academy. I credit AoPS for much of her confidence.
