Researcher Summary

Electrochemistry of redox processes of cells and isolated enzymes. Application of electrochemical techniques in whole cell and enzyme biosensors, and microbial fuel cells. Modification of electrode surfaces, mediated and non-mediated electron transfer from biological entities to the electrode.

I am interested in the use of electrochemical techniques to investigate redox processes in cells and enzymes and in the application of these techniques in whole cell biosensors, enzyme biosensors and microbial fuel cells. Most of my work involves yeast but other cells such as bacteria and mammalian cells are also investigated. Yeast cells have some advantages in these applications but have, to date, been less studied than bacteria.  In general yeast are more robust than bacteria and they can provide information that is more relevant to other eukaryote organisms than can bacteria.
