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 tackles removal of Bisphenol A from water using light-activated materials. By combining titania with a silica shell and a responsive polymer “gate,” the system adapts to changing conditions like pH and temperature, improving pollutant breakdown under visible light and enabling smarter, more efficient water purification.

This research addresses plastic waste by rethinking polyethylene recycling. Instead of breaking polymers down, it explores chemical upcycling—adding functional groups to create higher-value materials. By transforming waste into useful products, this approach aims to enable a circular plastics economy, reduce pollution, and provide sustainable alternatives to current inefficient recycling methods.

This talk explains how everyday consumer chemicals, especially in food and personal care products, can affect human and environmental health. It urges consumers to look beyond marketing claims, read ingredient lists carefully, understand which labels are meaningful, and reduce exposure to problematic compounds such as parabens and fragrances.

Traces of pharmaceuticals increasingly contaminate water through human use and improper disposal. This research studies advanced oxidation processes—using UV light, ozone, and hydrogen peroxide—to break down these persistent pollutants. Optimizing these treatments helps protect ecosystems and public health by ensuring clean, safe, pharmaceutical-free drinking water.

Textile waste in Australia decomposes slowly and releases toxic chemicals. Natural fibres like cotton could be composted, but dyes and treatments hinder breakdown. This PhD develops a new compost-testing method, measures dye impacts, and identifies toxic residues. The work will inform Australia’s first composting standard and help industry choose safer, circular textile dyes.
