Professor Passeport’s research interests are in the fate and removal of contaminants from water environments. In particular, her research focuses on better characterizing contaminant transfer and transformation processes in natural environments, using a variety of sampling techniques (e.g., passive sampling) and analytical methods (e.g., stable isotope analysis). Professor Passeport’s research group mimics these natural removal processes in engineered green infrastructures used for water treatment, such as constructed wetlands and bioretention cells. Her research group utilizes a chemical engineering unit operations approach to designing green infrastructures, incorporating and optimizing a series of treatment steps.
