Research Interests
My group performs research in environmental engineering and science with a focus on the fate, effects, and remediation of toxic pollutants in the environment. We use multidisciplinary tools to investigate exposure and bioavailability of organic and metal pollutants to organisms and apply the new understanding to develop novel approaches for risk assessment and remediation. Our research has contributed to the development and transition of sustainable sediment remediation technologies based on altering sediment geochemistry and enhancing biological degradation. Our research is breaking new ground and transforming the way engineering professionals and regulators approach remediation/restoration of polluted aquatic environments. We also led the development of monitoring tools for pollutant bioavailability, especially work on passive sampling for measuring freely dissolved concentrations in water. Our work has been published in the leading journals (Google Scholar)and the technology development has led to several US patents and commercialized technologies. The research contributions have been recognized through multiple awards including the University System of Maryland Board of Regents award for Excellence in Scholarship, Research, and Creative Activity in 2016. I am an Associate Editor of the journal Environmental Toxicology and Chemistry. I am also a co-founder of two startup companies Sediment Solutions LLC (manufacturer of SediMite), and RemBac Environmental that are transitioning emerging sediment remediation technologies to the field.
