Cheryl Elisabeth Praeger AC FAA (born 7 September 1948, Toowoomba, Queensland) is an Australian mathematician. Praeger received BSc (1969) and MSc degrees from the University of Queensland (1974), and a doctorate from the University of Oxford in 1973 under direction of Peter M. Neumann. She has published widely and has advised 27 PhD students (as of March 2018). She is currently Emeritus Professor of Mathematics at the University of Western Australia. She is best known for her works in group theory, algebraic graph theory and combinatorial designs.

Education

Praeger completed her high school education at Brisbane Girls Grammar School. After graduating high school, Praeger went to the government vocational guidance section to inquire about how she could further study mathematics. The vocational guidance officer she spoke with tried to discourage her from studying mathematics further,[1] suggesting she become a teacher or a nurse because two other girls who came to him wanting to study maths were not able to pass their courses.[1] He reluctantly showed her an engineering course description, but she felt it did not have enough mathematics. So she left without getting much information that day, but did continue on to receive her bachelor's and master's degrees from the University of Queensland.

Having met several women on the mathematics staff during her undergraduate studies, the prospect of becoming a mathematician did not seem strange to her. During her first and second years she did honours studies in mathematics and physics, choosing to continue in mathematics after her second year.[1] After completing her education at University of Queensland she was offered a research scholarship at Australian National University (ANU) but chose instead to take the Commonwealth Scholarship to the University of Oxford and attended St Anne's College. At that point she knew she wanted to study algebra.

After earning her doctorate in 1973, she obtained a research fellowship at ANU. She had her first opportunity at teaching regular classes at the University of Virginia during the semester she worked there. Afterwards, she returned to ANU, where she met her future husband, John Henstridge, who was studying statistics. She was later offered a short-term position at the University of Western Australia, which turned into a long term position, where she currently works today.[1] In 1989 she received the degree of Doctor of Science from the University of Western Australia for her work on permutation groups and algebraic graph theory.

Career

Her career has been largely spent in the Department of Mathematics and Statistics at the University of Western Australia. She was appointed full professor in 1983 and was head of the Department of Mathematics 1992–1994, inaugural dean of postgraduate research studies 1996–1998, chair Promotions and Tenure Committee 2000–2004, deputy dean of the Faculty of Engineering Computing and Mathematics 2003–2006, ARC Professorial Fellow 2007.[2] and ARC Federation Fellow in 2009.[3]

Praeger has supervised over 30 graduate students and in 1997 she supervised the Honours research work of Akshay Venkatesh who went on to win a 2018 Fields Medal, commonly regarded as the highest prize in mathematics.

During her career, Praeger has been invited to speak at many conferences, including ones in Croatia, Canada , China , USA, UK, South Korea , Singapore, Sweden, Slovakia, Serbia, Hong Kong, Morocco, Slovakia, Slovenia, France , Germany , Greece, USSR, Belgium, Iran, Italy, Pakistan , Philippines , and Japan .[1][4]

Praeger has been a member of the Curriculum Development Council of the Commonwealth Schools Commission,[17] the Prime Ministers Science Advisory Council, WISET Advisory Committee to the Federal Minister for Science on participation of women in Science, Engineering, and Technology, UWA Academy of Young Mathematicians Lectures, the Western Australian School Mathematics Enrichment Course Tutor, and Data Analysis Australia Pty Ltd. She has also served on the Australian Federation of University Women (Western Australian Branch) and the Nedlands Primary School Council.[4] Between 1992 and 2019 she was a board member of the Australian Mathematics Trust. From 2001 to 2019 she chaired the Australian Mathematical Olympiad Committee.[citation needed] She is currently a member of the National Science and Technology Council that provides advice to the prime minister and the minister for science.[18]

Between 2007 and 2014 Praeger was a member of the executive committee of the International Mathematical Union and between 2013 and 2016 a vice president of the International Commission on Mathematical Instruction.[19]

Between 2014 and 2018 Praeger was foreign secretary of the Australian Academy of Science.

She is a Member of the executive committee of the Inter Academy Partnership - Science, 2017–19. Since 2019 she has been a member of the Committee for Freedom and Responsibility in Science of the International Science Council.[20]

Praeger promotes the involvement of women in mathematics by encouraging girls in primary and secondary schools with lectures, workshops, conferences and through the Family Maths Program Australia (FAMPA), which she was key in implementing in local primary schools.[4] She is currently Patron of the Mathematical Association of Western Australia.

Personal life

In August 1975 Praeger married John Henstridge in Brisbane. They have two children, James (1979) and Tim (1982).[1]

In addition to holding a doctorate in mathematics, she also holds an Associate in Music, Australia (AMusA) in piano performance and was a member of the University of Western Australia Collegium Musicum between 1977 and 1985. She has been a member of the Uniting Church in Australia, Nedlands Parish since 1977, functioned as an elder from 1981 to 1987, and as an organist/pianist since 1985. She lists keyboard music among her stronger interests along with sailing, hiking, and cycling.[4]

Research

Praeger published her first research paper in1970 while she was still an undergraduate. Since then she has become one of the most highly cited authors in pure mathematics, with (as of December 2022) over 450 publications total. She is known as a collaborator, with over 200 co-authors.

Praeger's research is centred around the mathematics of symmetry, including key work in group theory (especially group actions and permutation groups), combinatorics, analysis of algorithms and complexity, discrete mathematics and geometry. Major areas and results include:

  • Praeger later went on to generalise the O'Nan–Scott Theorem to quasiprimitive groups.[24]
  • With Peter M Neumann she developed and analysed the first randomised algorithm to recognise finite special linear groups. This led to the international matrix group recognition project and was extended to all finite classical groups by Praeger and Alice Niemeyer.
