In PHILADELPHIA, PA, Marsha Berger, affiliated with New York University and the Flatiron Institute, has been awarded the prestigious 2025 John von Neumann Prize by the Society for Industrial and Applied Mathematics (SIAM). This honor recognizes her significant contributions to developing adaptive mesh refinement and embedded boundary methods for partial differential equations (PDEs).

Berger's influential research in adaptive mesh refinement and embedded boundary methods has been crucial across various scientific and engineering fields, including aerodynamics, astrophysics, cosmology, plasma physics, subsurface flow, engine design, and tsunami modeling. Her work has advanced method development and theoretical stability, creating efficient software for serial and parallel supercomputing systems.

As part of the award, Berger will deliver the flagship lecture at the upcoming SIAM/CAIMS Annual Meetings 2025 (AN25), scheduled for July 28 to August 1, 2025, in Montréal, Québec, Canada. This esteemed prize is awarded annually to an individual who has made outstanding contributions to applied mathematics and successfully communicated these ideas to the scientific community.

In expressing her gratitude for this prestigious recognition, Berger emphasized the importance of her work being instrumental and beneficial to others. She earned her Ph.D. from Stanford University in 1982 and has had a distinguished career as a computer science and mathematics professor at New York University's Courant Institute of Mathematical Sciences. After retiring from NYU in 2022, she became a senior research scientist at the Center for Computational Mathematics at the Flatiron Institute.

Berger's impactful research extends beyond academia, with practical applications in weather prediction, aircraft design, and tsunami simulations for disaster management in earthquake-prone regions. Her commitment to advancing computational fluid dynamics, mainly through adaptive mesh refinement techniques, highlights the essential role of numerical tools in addressing societal challenges.

For over four decades, Berger has been an active member of SIAM, contributing significantly through her involvement in various committees and editorial boards. Her dedication to bridging the fields of computer science and mathematics has been instrumental in shaping the intersection of these disciplines and facilitating innovative advancements in computational mathematics.

Established in 1959, the John von Neumann Prize honors the legacy of John von Neumann, a prominent mathematician, physicist, and computer scientist whose pioneering work laid the foundation for modern computing. Berger's receipt of this esteemed award further solidifies her status as a leading figure in applied mathematics and computational science.

In acknowledging Berger's groundbreaking contributions, the scientific community celebrates her personal achievements and the substantial impact of her research in enhancing the understanding and application of computational methods across diverse fields. This recognition emphasizes the critical role of mathematics in addressing complex challenges in our increasingly interconnected world.

Recent research from the Institute for Basic Science in Korea has utilized advanced supercomputer simulations to investigate the impact of climate change on global wildfire patterns. The simulations reveal that rising temperatures and changes in vegetation and humidity are driving an increase in wildfire intensity worldwide. Interestingly, the role of lightning as an ignition source is minimal compared to these environmental changes. This breakthrough enhances our understanding of future wildfire risks, aiding in better prediction and management strategies.

The study's findings indicate a concerning scenario where increasing greenhouse gas emissions are projected to increase global lightning frequency by approximately 1.6% for each degree Celsius of global warming. This increase in lightning activity could heighten wildfire occurrences in regions such as the eastern United States, Kenya, Uganda, and Argentina. However, while lightning contributes to wildfire ignition, the primary factors driving the expanding area burned each year are shifts in global humidity and accelerated vegetation growth, fueling wildfires.

Dr. Vincent Verjans, the study's lead author, warns that global warming has significant effects on ecosystems, infrastructure, and human health. Each degree of warming is estimated to increase the global mean area burned by wildfires annually by 14%. The study identifies regions such as southern and central equatorial Africa, Madagascar, Australia, and parts of the Mediterranean and western North America as the most vulnerable to intensified fires due to climate change.

Furthermore, the study highlights the cascading effects of increased wildfires on air pollution and sunlight penetration. As smoke plumes from wildfires grow, they contribute to regional temperature changes. The authors note that while the new supercomputer model simulations account for the direct aerosol effects of wildfires, further research is needed to fully understand how fires may impact cloud formation and subsequent surface temperatures.

While this study provides crucial insights into the complex interactions between climate change, lightning, and wildfires, it also emphasizes the urgency of addressing key aspects that require deeper examination. For instance, the researchers express concerns about the potential underestimation of future Arctic wildfire risks in current climate models and the implications for aerosol release and air quality.

The study calls for action to confront the growing threat of intensifying wildfires in a warming world and emphasizes the need for comprehensive earth system models to understand better and mitigate the far-reaching impacts of wildfires on our planet.
