Current research

This interdisciplinary PhD project investigates the use of nontarget screening and multivariate techniques to identify polar transformation products from wastewater treatment processes. To date this type of workflow has been used in metabolomics studies for the investigation of biomarkers but not yet in environmental research for the identification of emerging contaminants and their transformation products. This concept is being applied here to locate peaks in real-world wastewater samples that are characteristic of pre-treatment or post-treatment samples. Samples are measured with liquid chromatography coupled to high-resolution tandem mass spectrometry (LC-HRMS/MS) and the information from these measurements is critical for compound identification and structure elucidation. Confirmation of identified transformation products will be done through batch studies under defined conditions if reference standards are available for purchase. Additionally, the presence of these compounds in wastewater-impacted streams and their potential toxicity may be evaluated.
