Selina Tisler is an Assistant Professor in the Environmental Analytical Chemistry Group from University of Copenhagen since 2022. After receiving her PhD 2019 from University of Tuebingen in Germany, she was a postdoc at Aarhus University and University of Copenhagen in Denmark. Her research focus is the advanced analysis of water, including non-target screening of compounds of emerging concerns (CECs) in general and the identification of transformation products in the aquatic environment. Furthermore, she has a focus in the analysis of food contact materials by suspect and non-target screening, to extend the knowledge of compounds migrating into our drinking water. She works with liquid chromatography and supercritical fluid chromatography, both coupled to high-resolution mass spectrometry.
