Kathleen Murphy

Senior forskare at Chalmers, Architecture and Civil Engineering, Water Environment Technology

Kate Murphy’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.
