Susan’s main research interest is in how transporters function, with the aim of understanding their molecular mechanisms. Her team is using heterologous expression systems to characterize transporters, their mutant variants that have been generated by site-directed mutagenesis or random methods and to determine transmembrane topology. This allows researchers to characterise transporter function and test hypotheses about which regions of the transporter are important for function.
Susan’s research has covered a range of different proteins including nutrient transporters from plants and cyanobacteria to neurotransmitter receptors. Her current research has led to the development of the first heterologous expression system for cyanobacterial bicarbonate transporters, leading to an analysis of their structure and function.
Susan also undertakes educational research which currently addresses assessing the effectiveness of student research experiences, with the aim of identifying student views of scientific research and how this impacts on learning from undergraduate research projects.
