This research investigates phosphorus pollution in Lake Warner by comparing water movement and phosphorus transport through urban and forested landscapes. Forests naturally filter phosphorus due to slower water travel and greater infiltration, while urban runoff accelerates pollution. The study identifies how interventions such as rain gardens can reduce phosphorus loading into lakes.

This research examines how atmospheric aerosols influence cloud formation and rainfall, particularly under turbulent conditions. Using a laboratory cloud chamber and computer modeling, the study investigates how particle size and concentration affect droplet growth. The findings aim to improve climate models and weather forecasting in both polluted and clean environments.

This research develops stable-isotope tools to measure how microbes—the Earth’s “lungs”—breathe CO₂ in and out. Microbes are massively abundant and shape global climate. Findings show deep subsurface environments slowly emit CO₂, a process that may influence future climate dynamics as human-driven environmental changes accelerate.
