Ingrid Daubechies


Professor Ingrid Daubechies was awarded the Fudan-Zhongzhi Science Award for her remarkable contributions to wavelets, especially the orthogonal Daubechies wavelet and the biorthogonal CDF (Cohen-Daubechies-Feauveau) wavelet, her leadership in developing wavelet theory and modern time-frequency analysis which fundamentally changed image and signal processing, her deep influence on many areas of data analysis and scientific computing, and her contribution to image compression, analog-to-digital conversion and thresholding-based algorithms for inverse problems.


Professor Ingrid Daubechies’ contributions to wavelets range from the highly theoretical to the very practical, which include the constructions of orthonormal wavelet bases with compact support and an arbitrarily high degree of smoothness, and the work on biorthogonal wavelets (with Cohen and Feauveau, Comm. Pure Appl. Math, 1992) which is the mathematical foundation for the image processing algorithms based on the wavelet multi-scale paradigm and one of which is now used in the JPEG 2000 standard. In addition, She also has abundant contributions in other fields. For example, in the numerical solution of inverse problems, she and her collaborators developed a class of algorithms for inverse problems based on the use of frame decompositions and thresholding. Besides, in redundant signal representations, she developed an approximation-theoretical framework for oversampled coarse quantization and designed an infinite family of stable one-bit sigma-delta modulators. Her work has had exceptionally broad scientific impact, not only on mathematics but also on many areas of science and engineering.


Professor Ingrid Daubechies is a member of the National Academy of Sciences, the National Academy of Engineering, and the American Academy of Arts and Sciences. She become a fellow of the MacArthur Foundation and received the National Academy of Sciences Award in Mathematics for her seminal contribution to research, also she won the Leroy P. Steele Prize for her book Ten Lectures on Wavelets. She was the first women to be the president of the International Mathematical Union (2011-2014). In 2012, King Albert II of Belgium granted Daubechies the title of Baroness.
