Dr. Jonah Ostroff,
Director (2015--2018), Lead Instructor (2015--present)

Jonah is a senior lecturer in the math department at the University of Washington. He earned his Ph.D. in mathematics at Brandeis University in 2013 after studying at Carleton College. His research is focused on enumerative graph theory and permutation patterns, but he's also pretty into the mathematics of games and elections. He was a student of the MathILy director at the Hampshire College Summer Studies in Mathematics in 2002 and 2003, before which he thought math was only kind of okay. (He has since changed his mind.) Jonah has taught at various Math Circles for the last decade, directed the first four years of MathILy-Er, and taught at MathILy-Ers 2015--2020. He knows all the digits of 22/7.

As of the Spring, he is working on his final year at Arizona State University and will graduate in May. JD loves board games and problem-solving, and he's excited to share the wonders of math with more students!

Evan Forletta, Apprentice Instructor (2018)

Evan is a third year transfer student at UC Santa Cruz, where he studies all the pure math he can get his hands on. Some of his favorite things include: singing, coffee, his letter/number color synesthesia, and watching his little brother perform in band competitions. This quarter he's gonna see if he can't learn some algebraic geometry, as well as try to go to bed earlier (one could debate which is harder---the uninterrupted hours that span 10pm to 4am are a hard-to-resist time for mathematics...). Aside from just learning mathematics, Evan's real mission in life is to share that math with other people (i.e. be what they call a teacher). Trust us: this kid really looks forward to meeting you all this summer.

Hannah Turner, Apprentice Instructor (2017)
