Her Journey in Mathematics
Early Studies and Teaching
Christiane Rousseau earned her Ph.D. (a very high university degree) in mathematics in 1977. She studied at the Université de Montréal. Her special research project was about "Topos Theory and Complex Analysis."
After her Ph.D., she did more research at McGill University. In 1979, she started teaching at the University of Montreal. She became a full professor in 1991. From 2008 to 2009, she was the temporary director of the Centre de Recherches Mathématiques.
Leading Roles in Math Organizations
Christiane Rousseau made history as the first female vice-president of the International Mathematical Union. She held this important role from 2011 to 2014.
She also started and led a big project called "Mathematics on Planet Earth" in 2013. This project, known as MPE 2013, had support from UNESCO. She also played a key part in making March 14 the International Day of Mathematics, recognized by UNESCO.
What She Studies
Exploring Equations and Systems
Christiane Rousseau's main research areas are differential equations and dynamical systems. These are types of math that help us understand how things change over time.
She studies special points in differential equations. She also works on bifurcation theory, which looks at how systems change suddenly. Part of her work includes Hilbert's sixteenth problem, which is a famous math challenge.
Math in Biology and Other Fields
She also uses math to understand biology. For example, she has studied the Lotka–Volterra equations. These equations help explain how populations of predators and prey interact.
Christiane Rousseau is also interested in how Lie algebra can be used in physics. This includes ideas related to the Grand Unified Theory.
Sharing Math with Everyone
She loves to share her passion for mathematics. She gives presentations in high schools and colleges (called cégeps in Quebec). She has also written over 35 articles to explain math in a simple way. These articles appear in a journal called Accromath.
Awards and Honors
Christiane Rousseau has received many awards for her work. She earned the Adrien-Pouliot Prize and the Abel-Gauthier Prize. These awards are from the Mathematical Association of Québec.
In 2009, she received the Graham Wright Award for Distinguished Service. This award came from the Canadian Mathematical Society. In 2014, she won the George Pólya Award from the Mathematical Association of America. This was for her article about how Inge Lehmann discovered the Earth's inner core.
In 2012, she became a fellow of the American Mathematical Society (AMS). This means she was recognized as a top member. In 2017, she was the first person to receive the AMS' Bertrand Russell prize. This award honors people who use math to help human values and the common good.
In 2018, the Canadian Mathematical Society named her one of their first fellows. In 2024, she was appointed as an officer to the Order of Canada. This is one of Canada's highest honors. She lives in Mont-Saint-Grégoire, Quebec.
