Dr. Sally Brown
Research Associate Professor:
My research has centered around cleaning things up, generally contaminated soils. My first efforts were with metal hyperaccumulator plants and more recently with different soil amendments.
Soil amendments, in the form of residuals from different industries (municipal biosolids, composts, high calcium carbonate wastes...) offer the potential to do more than fix contaminated sites. Increased and targeted uses of these materials offer the potential for us to live in a more sustainable manner.
Lately, I've been focusing on innovative uses for these materials in the hopes that identifying different uses and benefits for residuals will result in greater public acceptance.
My research partners and I have worked on studies involving soil health, climate change mitigation, biosolids recycling and wastewater treatment:
