Mark Servos
Biography
Dr. Mark Servos is a Professor in the Department of Biology at the University of Waterloo, where his research and teaching program is related to the science underlying risk assessment and management of emerging threats to water resources.
He is an internationally recognized researcher in environmental assessment and risk of emerging contaminants of concern, including endocrine disruptors, pharmaceuticals and personal care products. Servos and his group have conducted numerous studies examining the fate, effects and remediation of emerging contaminants in a variety of sectors including extensive studies on municipal wastewaters. His research also develops innovative technologies to remove these contaminants from water and tests remedial actions to minimize their risks. He is improving frameworks to assess and remediate multiple stressors and their cumulative effects on ecosystems across watersheds. With the onset of the COVID-19 pandemic, Mark and his team pivoted their research on wastewater and environmental DNA (eDNA) to focus on detection of SARS-CoV-2 gene fragments in wastewater systems, supporting public health agencies to understand trends in community infections. This research now extends to the development of wastewater-based surveillance to additional pathogens and high-risk substances such as “drugs of abuse” to better inform public health interventions.
Servos leads discovery as well as applied research examining how environmental contaminants affect the sustainability of watersheds and ecosystems. Drawing on extensive government experience, his work is closely aligned with partners to generate evidence that supports remediation efforts and improved environmental policy for long‑term ecological health. His current work continues to support the protection, remediation and sustainability of aquatic ecosystems locally, nationally and globally.
