Preparing Communities for the Future of Wildfire

By Elyse DeFranco | Oct 28, 2025 | Featured projects

Last year saw DRI’s inaugural global initiative aimed at advancing community resilience and adaptability in the face of rapid global change – AWE+, for an Adaptable World Environment. The event brought together hundreds of scientific experts, policymakers, resource managers, and other stakeholders to discuss ways to strengthen our communities against the growing threat of wildfires. To maintain momentum on the topic and continue building relationships that advance resilience, DRI’s 2025 AWE+ event sought to build on these conversations, again focusing on wildfire and bringing experts together from across the nation.

Household Dryers Are Significant Sources of Microfiber Pollution, Study Finds

By Elyse DeFranco | Oct 15, 2025 | News releases, Research findings

The fabrics that fill our homes, from natural cotton towels and bedsheets, to clothes produced with synthetic materials, produce microscopic fibers as they break down over time. Previous research has shown that household washers collect and release these microfibers into the environment, and now a new study uses citizen science to demonstrate how dryer vents also produce microfibers under normal household use.

DRI Recognizes Ashley Cornish as the 2025 Peter B. Wagner Memorial Award Winner for Women in Atmospheric Sciences

By Elyse DeFranco | Oct 8, 2025 | Awards and Honors

DRI is pleased to announce that the 27th annual Peter B. Wagner Memorial Award for Women in Atmospheric Sciences has been awarded to Ashley Cornish of the University of Georgia. The Peter B. Wagner Memorial Award for Women in Atmospheric Sciences is an annual competition recognizing the published works of women pursuing a master’s or Ph.D. in the atmospheric sciences or any related program at a university in the United States. The award is presented to women graduate students with outstanding academic publications and includes a $1,500 prize. This award has been presented annually by DRI since 1998 and is the only such honor designated for graduate women in the atmospheric sciences in the United States.

Scientists Successfully Recreate Wildfire-Induced Thunderstorms in Earth System Models for the First Time

By Elyse DeFranco | Sep 29, 2025 | Research findings

The breakthrough enhances scientific understanding of the dangerous storms and their long-term impacts on the climate. The research, published September 25th in Geophysical Research Letters, represents the first successful simulation of these wildfire-induced storms, known as pyrocumulonimbus clouds, within an Earth system model. Led by DRI scientist Ziming Ke, the study successfully reproduced the observed timing, height, and strength of the Creek Fire’s thunderhead – one of the largest known pyrocumulonimbus clouds seen in the U.S., according to NASA.

DRI Launches Collaborative New Project Investigating PFAS and Microplastics for Department of Defense

By Elyse DeFranco | Aug 27, 2025 | Featured projects

DRI’s Monica Arienzo, Director of the Microplastics and Environmental Chemistry Laboratory, was recently awarded $250,000 by the Department of Defense to investigate laundering and textile degradation as a possible source of PFAS and microplastic pollution. The one-year grant will fund laboratory studies and analysis led by Arienzo, with DRI’s Daniel Saftner and Yeongkwon Son contributing to the work. Matt Reeves of Western Michigan University is partnering with the DRI scientists for the project.
