Roger Temam


Roger Meyer Temam is a French applied mathematician working in several areas of applied mathematics including numerical analysis, nonlinear partial differential equations and fluid mechanics. He graduated from the University of Paris – the Sorbonne in 1967, completing a higher doctorate prepared under the direction of Jacques-Louis Lions. He published over 400 articles which appeared in major scientific journals, as well as 12 books some of which have been translated in different languages, including English, Russian, and Chinese. Three of his books are now published in permanent series.

Scientific work

The scientific work of Roger Temam, which is at the interface between mathematical analysis, numerical analysis and scientific computing, includes mathematical modeling and analysis, as well as the development of novel numerical methods. The first work of Roger Temam in his thesis dealt with the fractional steps method. Thereafter, he has continually explored and developed new directions and techniques:
The main activities of Roger Temam nowadays concern the study of geophysical flows, the atmosphere and oceans. This started in the 1990s by collaboration with Jacques-Louis Lions and Shouhong Wang.
″The influence of Roger Temam in the development of applied mathematics in France, as well as all over the world, has been substantial.″ His scientific influence can also be measured in the number of doctoral theses that he has supervised, both in France and in the United States. According to the Mathematical Genealogy Project database, he holds the first position in the top 50 advisors. More than 30 of his students are now full professors all over the world, and have themselves many descendants.

Administrative activities

Besides his scientific work, Roger Temam has engaged in various administrative activities. He became a professor at the Paris-Sud University at Orsay in 1968. There, he co-founded the Laboratory of Numerical and Functional Analysis which he directed from 1972 to 1988. He was also a Maître de Conférences at the Ecole Polytechnique in Paris from 1968 to 1986.
In 1983, Roger Temam co-founded the French Société de Mathématiques Appliquées et Industrielles, analogous to the Society for Industrial and Applied Mathematics, and served as its first president. He was also one of the founders of the International Congress on Industrial and Applied Mathematics series and was the chair of the steering committee of the first ICIAM meeting held in Paris in 1987; and the chair of the standing committee of the second ICIAM meeting held in Washington, D.C., in 1991. He was also the Editor-in-Chief of the mathematical journal M2AN from 1986 to 1997, and has served or is serving on the editorial board of such journals as Asymptotic Analysis, Discrete and Continuous Dynamical Systems, Journal of Differential Equations, Physica D, Communications in Partial Differential Equations and SIAM Journal on Numerical Analysis.
″Roger Temam also has a very successful career in the United States.″ He has been the Director of the Institute for Scientific Computing & Applied Mathematics at Indiana University since 1986. He is also a College Professor and he has been a Distinguished Professor since 2014.
