2023 IBB World Championship Announcement

Winners of the 2023 International Brain Bee

Chun Hei Tai, a 16-year-old student from Hong-Kong is the winner of the 25th International Brain Bee and the 2023 IBB World Champion. Second place went to Stanley Zhang from New Zealand, and third place to Kimia Ahmadi from Iran. The World Championship took place in conjunction with the American Psychological Association (APA) Annual Convention in Washington, DC, this year’s host conference.

The IBB is the world’s premier neuroscience competition for teenagers. The World Championship brings together students from across the world for an exciting competition and educational experience. A total of
31 national Brain Bee champions from across the globe took part in the virtual 2023 event held from July 31-August 5. Each competitor had previously won the highest level of Brain Bee competition in their
country to qualify for the World Championship.

The challenging competition was conducted in two parts. All competitors completed four separate tests (written exam, neuroanatomy, neurohistology, and patient diagnosis) within a 48-hour timeframe at the beginning of the World Championship. Based on their total combined scores, 14 finalists advanced to the Live Judging Session, a question-and-answer round with four prominent neuroscientist judges. Two special guests introduced the finalists and announced the top three finishers at the award ceremony: 2022 World
Champion Helene Li from Canada, and 2022 third-prize winner Ugne Birstonaite from Lithuania.

“APA was honored to host this year’s World Championship on the 25th anniversary of the IBB and the 5th anniversary of its incorporation. I am proud of all our National Champions and their achievements,” says
Jaime Diaz-Granados (IBB Board Chair and Deputy CEO of APA).
