Several area students earned medals in the ninth annual China Girls Mathematical Olympiad, which took place Aug. 9-13 in Shijiazhuang, China. The event, which drew 190 girls from 10 countries, was sponsored by the Mathematical Sciences Research Institute of Berkeley, Calif.

The students receiving gold medals in the competition included Elizabeth Synge of Lexington, a senior at Boston University Academy in Boston; Jae Eui Shin of Andover, a senior at Phillips Academy in Andover; and Shijie Joy Zheng of Bellevue, Wash., a senior at Phillips Exeter Academy in New Hampshire.

Among the other award recipients, Adisa Kruayatidee, a senior at Phillips Exeter Academy from Stevenson Ranch, Calif., was given a bronze medal; and Stoneham resident Andi Wang, who is entering the Massachusetts Institute of Technology as a freshman this fall, earned an honorable mention.

The US team’s coach was Zuming Feng, a math teacher at Phillips Exeter Academy who is also the leader of the USA International Mathematical Olympiad team, and director of the Mathematical Olympiad Summer Program. Assistant coaches were Inna Zakharevich, a graduate student at MIT, and Sherry Gong, who attends Harvard University.
