Olof B. Widlund is the Silver Professor of Mathematics and Computer Science at the Courant Institute of Mathematical Sciences , New York University , where he has been a leading figure in numerical analysis and scientific computing for decades. His research focuses on domain decomposition methods for partial differential equations, particularly in the context of large-scale parallel computation. Widlund’s work has significantly advanced the theory and application of iterative substructuring and Schwarz methods, including FETI-DP and BDDC algorithms, for problems in elasticity, fluid dynamics, and electromagnetics. He co-authored the award-winning monograph Domain Decomposition Methods – Algorithms and Theory (Springer, 2005), which received the Association of American Publishers’ Excellence Award in 2006. His recent research includes hybrid domain decomposition methods, isogeometric analysis, and adaptive selection of primal constraints. The trends in his publications show a sustained focus on robust, scalable preconditioners for elliptic systems, H(curl) and H(div) problems, and nearly incompressible materials, with strong emphasis on theoretical analysis and practical implementation. Scientific Awards: Award for Excellence in Professional and Scholarly Publications, Association of American Publishers, Mathematics and Statistics (2006) Research Sponsorship and Leadership: His work has been supported by the National Science Foundation (NSF DMS-1522736) and the U.S. Department of Energy . He was the institutional lead for the DOE SciDAC TOPS project until 2007 and co-PI on earlier multi-institutional computational methods initiatives. Advising: Widlund has advised 31 doctoral students, many of whom have become leaders in numerical analysis and computational science. His students have worked on spectral elements, mortar methods, Stokes solvers, and BDDC/FETI algorithms. Community Engagement: He is a regular participant in the International Conferences on Domain Decomposition and delivered a full-day tutorial prior to the 20th conference in 2011. A special conference was held in his honor at Courant in 2008 for his 70th birthday.
