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 investigates heavy metal contamination in fish from the Arabian Gulf. Using advanced laboratory techniques, trace elements such as arsenic, lead, and mercury are measured in edible tissues to assess food safety and determine whether local fish consumption poses risks to human health.
