Research Interests

Our interests focus on the investigation of electrochemical behavior and the harnessing of that behaviour for beneficial applications. These interests are consistent with the needs of society for the detection of substances, be they biomarkers of disease, pollutants or contaminants, in simple, reliable formats, such as hand-held analysers, integrated microsystems and autonomous sensors that operate at the point-of-need.

We are especially interested in exploring the bioanalytical capabilities of electrochemistry at interfaces between immiscible liquids as well as combining such electrochemistry with the benefits to be obtained from miniaturisation. This leads to interests in protein, peptide and drug substance electrochemistry, in micro- and nanoscale liquid-liquid interfaces and in microfluidics.
