Zuming Feng graduated with a PhD from Johns Hopkins University with emphasis on Algebraic Number Theory and Elliptic Curves. He teaches at Phillips Exeter Academy from 1995 to present. Zuming served as a coach of the USA International Mathematics Olympiad (IMO) team from 1997 to 2015, was the deputy leader of the USA IMO delegation from 2000-2002, an assistant director of the USA Mathematical Olympiad Summer Program (MOSP) from 1999-2002, the leader of the USA IMO delegation the academic director of the MOSP from 2003 to 2013. In this period, Zuming and MOSP staff members (Melanie Wood and PoShen Loh in particular) worked with Mathematical Sciences Research Institute (MSRI), Mathematics Association of America (MAA) and National Science Foundation (NSF) to build the USA Girls Math Olympiad team – a program to get more female students in middle and high school involved in high-level mathematics competitions. It is also in this period that Zuming and his colleagues at American Math Competition (AMC)/MOSP started at USA Junior Math Olympiad (USAJMO) and current USA IMO team year-long selection and training process. He is a member of the USA Mathematical Olympiad Committee since 1999 and a member of American Invitational Math Exam (AIME) since 2016. Zuming was a coordinator at IMO 2015 and 2017. He designed and taught the course Mathematical Problem Solving (Math 199) at Yale University from 2013 to 2015. Zuming served as academic director for a few problem solving based math summer/winter programs from 2006 to 2009. Since 2007, Zuming has co-founded and ran the IDEA MATH program. IDEA MATH has online program, weekday and weekend programs in Lexington (MA) and Plano/Frisco (TX), winter program in Lexington (MA), Houston (TX) and San Jose (CA), and summer programs in Nashua (NH), San Jose (CA), and Plano (TX). Zuming has many publications in contest mathematics. Zuming received the Edyth May Sliffe Award for Distinguished High School Mathematics Teaching from the MAA in 1996 and 2002. Zuming is a board member of the newly founded Proof School in San Francisco and COGITO by Johns Hopkins University CTY SET program.
