This research investigates atmospheric trace elements as indicators of pollution sources, focusing on toxic metal emissions from urban firestorms during the Eaton Canyon and Palisades fires. Elevated airborne lead concentrations prompted the creation of Phoenix, a community-based post-fire air monitoring network designed to track hazardous dust resuspension during debris cleanup.

This research compares Earth’s energy balance to a personal budget and examines how aerosols—especially black carbon—disturb that balance. By simulating how black carbon interacts with cloud droplets and light, the study helps improve understanding of climate impacts. The goal is better climate modeling and reducing harmful atmospheric pollution.

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.
