Sarah holds a PhD in Chemistry from the University of Manchester as well as a BSc in Chemistry from UMIST and a MSc in Environmental Science from the University of Nottingham.
She has previously worked as a Post-doctoral Research Associate at Washington State University, Los Alamos National Laboratory and the University of Leeds and as a Research Scientist at the Idaho National Laboratory.
Sarah joined the University of Sheffield in November 2021 as Experimental Officer in Aqueous Geochemistry, focussing on the analysis of samples using ICP-MS and ICP-OES.

- Research interests
Sarah’s research interests lie in understanding the fate and transport of contaminants either in environmental systems or in industrial process, with the ultimate aim of developing new remediation strategies to prevent/mitigate their impact. I am also interested in the development of new analytical methods under non-ideal conditions, for example high saline, strongly complexing or anoxic systems
In addition to this, she has developed analytical methodologies to support the detection of different species under challenging environments, e.g. high brine solutions, very low pH solutions, strongly complexing systems or anoxic/reducing conditions.
