Known in Ghana as the Maths Queen, Dr Angela Tabiri is the first African to win The Big Internet Math Off competition - quite an achievement for someone who had not initially planned to study mathematics.
The 35-year-old Ghanaian "finds joy in solving puzzles and mathematical questions" and hopes her 2024 win will open up the world of mathematics to other African women - who have traditionally been discouraged from taking the subject.
Sixteen mathematicians were invited to compete for the tongue-in-cheek title of "the world's most interesting mathematician" - a public vote event started in 2018 by The Aperiodical blog.
The first winner was Dr Nira Chamberlain, the first black mathematician to be included in the British reference book Who's Who and a vice-president of the professional body, the Institute of Mathematics and its Applications.
