PHILADELPHIA, PA — Marsha Berger, a trailblazer in the fields of adaptive mesh refinement and embedded boundary methods for partial differential equations (PDEs), has been awarded the 2025 John von Neumann Prize by the Society for Industrial and Applied Mathematics (SIAM). This prestigious honor recognizes her groundbreaking contributions to applied mathematics and her ability to communicate these ideas effectively to the broader scientific community.
Berger’s innovative work has played a pivotal role in advancing simulation methodologies for PDEs, with applications stretching across disciplines such as aerodynamics, astrophysics, tsunami modeling, engine design, and plasma physics. Her research has not only pushed the boundaries of theoretical stability and accuracy but has also resulted in efficient computational tools for both standard and high-performance systems.
“I’m excited and grateful to be recognized by my peers,” Berger said. “Knowing that my work has been used and helpful to others is a big motivator for me.”
A Distinguished Career in Science and Innovation
Berger earned her Ph.D. from Stanford University in 1982 and embarked on a career that would bridge mathematics and computer science. She joined the Courant Institute of Mathematical Sciences at New York University (NYU) as a professor and later made significant contributions to computational fluid dynamics during her work at NASA’s Ames Research Center. At NASA, she was a key figure in the development of the Cartesian cut-cell method Cart3D, a breakthrough in aerodynamic simulation.
Her influence extended beyond academia and research institutions. Berger became a role model in a field often considered niche, blending computer science and applied mathematics in the early years of computational science. She was elected to the National Academy of Science in 2000 and continued to drive innovation until her retirement from NYU in 2022. Following her time at NYU, Berger joined the Center for Computational Mathematics at the Flatiron Institute, serving as a senior research scientist.
The Broad Impact of Berger’s Work
Throughout her career, Berger has been an advocate for the far-reaching applications of computational science. From weather prediction to airplane design, her work in adaptive mesh refinement has improved the accuracy and efficiency of simulations critical to daily life. One noteworthy application of her methods is tsunami modeling, which is used to inform evacuation planning in the event of seismic disasters.
“Most people wouldn’t realize it, but computational fluid dynamics, and in particular adaptive mesh refinement, plays a key role in many of the simulations that impact daily life,” she explained.
Berger’s extensive involvement with SIAM reflects her commitment to advancing the field. A SIAM Fellow since 2009, she has held numerous leadership positions, including serving on SIAM’s Board of Trustees and multiple prize and committee boards. Her contributions have not only strengthened the organization but also paved the way for future innovators in computational and applied mathematics.
Recognizing Excellence in Applied Mathematics
The John von Neumann Prize, established in 1959, is SIAM’s highest honor. Named after John von Neumann, one of the foundations of modern computing and applied mathematics, the prize celebrates individuals whose work has had a profound impact on the field. Berger will formally receive the award and deliver the associated prize lecture during the SIAM/CAIMS Annual Meetings in Montréal, Canada, from July 28 to August 1, 2025.
A Legacy of Innovation and Inspiration
For over four decades, Berger has demonstrated the power of applied mathematics to solve complex, real-world problems. Her pioneering work, coupled with her enduring dedication to mentoring and collaboration, stands as an example for the next generation of mathematicians and scientists.
With her achievements now further cemented by the John von Neumann Prize, Berger’s influence on applied mathematics and computational science will continue to inspire new advancements in the years to come.
