Bill Sun, a recent graduate of Seven Lakes High School in Katy, earned a silver medal in the 2025 USA Biolympiad (USABO) National Finals at Harvard University in Cambridge, Massachusetts, according to a July 16 press release from USABO. Nearly 11,000 students from 741 schools, 47 states, and 36 international schools registered in the nationwide high school competition from June 22 to July 4, 2025.

Last year Sun earned a gold medal at the USABO National Finals held at Marymount University on its Arlington, Virginia, main campus from May 25-June 8, 2024. He subsequently represented the US as a member of the USA Biolympiad Team at the 35th International Biology Olympiad (IBO) held in Astana, Kazakhstan, where he earned a gold medal. Sun will be attending MIT in the fall.

“CEE is proud of the USABO finalists who are future leaders in bio-based careers,” said Joann DiGennaro, president of the Center for Excellence in Education.

During the ten days of the USABO National Finals, students participated in intensive theoretical and practical tutorials. The high school students studied with leading U.S. biologists in the fields of cellular and molecular biology, plant anatomy and physiology, animal anatomy and physiology, genetics and evolution, ecology, ethology, and biosystematics. The young scholars were mentored by Kathy Frame, USABO Director, and Logan McCarty, Associate Dean for Science Undergraduate Education, Harvard University.

“This is an incredible journey USABO students take, and it demonstrates the passion these students have for biological sciences,” said Kathy Frame, director of the USA Biolympiad at the Center for Excellence in Education.
