The Maths Queen with a quantum mission to mentor girls
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.
During the event they all compete against each other - so two in each match - and then it goes to quarter-finals and semi-finals until the big match to decide who has explained their chosen mathematical concept in the most illuminating way.
Dr Tabiri's passion is quantum, or non-commutative, algebra, which she researches at the Ghana branch of the African Institute for Mathematical Sciences (Aims).
Aims started in South Africa and then expanded to Ghana, Senegal, Cameroon and Rwanda - to provide post-graduate training and research in science, technology, engineering and mathematics.
Dr Tabiri is also the academic manager for the Girls in Mathematical Sciences Programme, a mentoring and support scheme for high or secondary school girls in Ghana.
It was set up by Aims-Ghana in 2020 to "ensure that we have a pipeline of young girls who will be leading in research and innovation in the mathematical sciences - in academia and also industry".
