Dr Mosekiemang is an environmental chemist with research interest in separation science (liquid & supercritical chromatography), mass spectrometry and method development and/or validation for the detection of novel organic pollutants in wastewater. His expertise is on instrumental analysis in particular application of novel separation methods to detect organic pollutants in very complex samples. Dr Mosekiemang's research group focuses on all aspects of environmental instrumental analysis. In particular wide scope screening for novel aquatic pollutants in aquatic ecosystems.
