Cheryl Praeger

Cheryl Praeger ( born September 7, 1948 in Toowoomba, Queensland ) is an Australian mathematician who deals with combinatorics and group theory.

Praeger ( the name comes from German ancestors from Chemnitz) went near Brisbane to school, studied at the University of Queensland and was established in 1974 at the University of Oxford ( St Anne 's College ) with Peter Neumann PhD ( On the Sylow subgroups of primitive permutation groups). As a post - graduate student, she was from 1973 at the Institute of Advanced Studies at the Australian National University. She is a professor at the University of Western Australia, where she is since 1976, then as a lecturer. She was its board of the Faculty of Mathematics and in 1996 Dean of Postgraduate Studies.

Praeger deals with finite and infinite permutation groups, group-theoretic algorithms, theory of finite groups, algebraic graph theory, finite geometry, theory of designs, applications of group theory in algebraic number theory, experimental design. She turned the group theory also on web problems. By 2006, she published more than 250 scientific papers and several books.

In 1968, she proved the conjecture of Charles Sims ( 1968) in the theory of permutation groups.

Praeger is a Fellow of the Australian Academy of Sciences and was from 1992 to 1994 president of the Australian Mathematical Society. She is an honorary doctor of Prince of Songkla University ( 1993) in Thailand and the Université Libre de Bruxelles ( 2005). In 2009 she was Western Australia Scientist of the Year. She became a member of the Order of Australia and in 2003 she was awarded the Centenary Medal by the Australian government in 1999. In 2002 he was invited speaker at the International Congress of Mathematicians in Beijing ( permutation groups and normal subgroups ). She is a Fellow of the American Mathematical Society.

She is married to the statistician John Henstridge and has two children. She plays the piano and is organist at her church. Other hobbies include hiking, cycling, sailing, wool spinning.
