from Wikipedia, the free encyclopedia

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

Cheryl Praeger Oberwolfach 2007

Praeger (the German name comes from ancestors in Chemnitz ) went to school near Brisbane , studied at the University of Queensland and received his doctorate in 1974 at the University of Oxford (St. Anne's College) with Peter Neumann ( On the Sylow subgroups of primitive permutation groups ) . As a post-doctoral student, she was at the Institute of Advanced Studies at the Australian National University from 1973 . She is a professor at the University of Western Australia , where she has been since 1976, when she was a lecturer. There she was head of the mathematics faculty and from 1996 dean for postgraduate studies .

Praeger deals with finite and infinite permutation groups, group theoretical algorithms, finite group theory, algebraic graph theory, finite geometry, theory of designs, applications of group theory in algebraic number theory, experimental planning. She also applied group theory to web problems. By 2006 she published over 250 scientific papers and several books.

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

Praeger is a Fellow of the Australian Academy of Sciences and was President of the Australian Mathematical Society from 1992 to 1994 . She is an honorary doctor of the Prince of Songkla University (1993) in Thailand and the Université Libre de Bruxelles (2005). In 2009 she was named Western Australia Scientist of the Year. In 1999 she became a member of the Order of Australia and in 2003 she received the Centenary Medal of the Australian Government. In 2002 she was invited speaker at the International Congress of Mathematicians in Beijing (permutation groups and normal subgroups) . In 2011 she received the Euler Medal , in 2014 the George Szekeres Medal , and in 2019 the Prime Minister's Prizes for Science . She is a Fellow of the American Mathematical Society .

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