The International Council for Industrial and Applied Mathematics (ICIAM) is a worldwide organization for professional applied mathematics societies, and for other societies with a significant interest in industrial or applied mathematics.

The Collatz Prize was established to provide international recognition to individual scientists for outstanding work on industrial and applied mathematics. A recipient’s 42nd birthday must not occur before 1 January of the year in which the prize is presented. It was created on the initiative of GAMM (Gesellschaft für Angewandte Mathematik und Mechanik), and first awarded in 1999.


The 2015 ICIAM Collatz Prize is awarded to Annalisa Buffa in recognition of her spectacular use of deep and sophisticated mathematical concepts to obtain outstanding contributions to the development of computer simulations in science and industry.

Buffa is Director of the Institute for Applied Mathematics and Information Technologies (Pavia-Genoa-Milan section).

In a relatively short amount of time, Buffa has been able to bring funda- mental contributions to a number of different aspects of scientific computing, with an incredible range both in the type of applications and in the type of mathematical instruments. The trademark of her work is the use of highly sophisticated mathematical techniques to produce fundamental breakthroughs that are applied to computer simulations in industry.
