It’s been quite a biology summer for Mercer Island resident Emma Li. First, the 16-year-old earned a gold medal at the 12-day Center for Excellence in Education’s USA Biolympiad (USABO) National Finals for high school students at Harvard University in Cambridge, Massachusetts. And now, the Lakeside School of Seattle rising senior is one of four U.S. gold-medal scholars who qualified for the 37th International Biology Olympiad (IBO) in Vilnius, Lithuania. The premier event is set for July 12-19.
