Areas of Interest
- Environmental Nanotechnology/Nanobiotechnology
- Environmental Chemistry and Remediation
Fundamental areas of research interest include assessing the interactions of engineered and biogenic nanomaterials with inorganic (mineral) and organic (plant) surfaces, assessing the fate of engineered nanocarriers in plants and soils, understanding how surface interactions affect the sorption and reactivity of organic water contaminants (e.g., PFAS), mercury geochemistry, developing and testing groundwater and soil remediation technologies.
Current projects include the development of efficient nano-carriers for efficient delivery of agrochemicals into plants, remediation, and destruction of perfluoroalkyl substances in groundwater, development and sensors for autonomous soil characterization with robots, and bioreduction of selenium in powerplant wastewater.

Greg Lowry and Astrid Avellan: Discovering how Nanoparticles Dissolve in Natural Water Environments
CEE Professor Greg Lowry and Postdoc Astrid Avellan describe their work looking at how nanomaterials behave in very complex environments using mesocosms that represent freshwater, emergent wetlands. They studied the behavior of gold nanoparticles in the mesocosms and discovered that gold was not inert, as they expected, but rather was transformed quite a bit by organisms in the environment.
