Kathleen Murphy

Senior Researcher at Water Environment Technology

Kate Murphy is Associate professor in the Division of Water Environment Technology, research theme Hazards and risks for drinking water resources and treatment, at Chalmers.

Kate's research focuses on the interpretation of fluorescence from dissolved organic matter in natural waters and the application of fluorescence for distinguishing between water sources and detecting changes in water quality. Recent research projects relate to detecting changes in organic matter character during recycled and drinking water treatment, and tracing the geographical origin of ships’ ballast water. She has instigated several open-source projects aimed at improving the modelling and interpretation of natural organic matter fluorescence, including the MATLAB toolbox drEEM and the online database of fluorescence spectra OpenFluor.
