our research

The presence of xenobiotics, such as engineered nanomaterials, pharmaceuticals and illicit drugs, and personal care products in the environment has raised concerns about the impact of these contaminants on the environment and on public health. However, there are still large knowledge gaps that interfere with the ability of regulatory agencies and municipalities to make informed decisions that will protect the environment, water systems and public health from the impacts of contaminants of emerging concern (CECs). In addition, the currently available knowledge is insufficient to allow proposing ways to control the release of CECs into the environment. Our research program is multi-disciplinary, including chemical and environmental engineering, analytical chemistry, microbiology and ecotoxicology. The main research activities of the group, developed with the long-term objective of protecting our water resources, span three main research areas:


Developing/Improving treatment technologies for municipal and industrial wastewaters to mitigate the release and impacts of CECs



Studying the nature and toxicity of transformation products of CECs and treated wastewaters



Performing environmental assessment to evaluate the contribution of wastewater to discharges of CECs into the environment and the potential for wastewater treatment to mitigate environmental impacts.
