Life in our Research Group
The actions of bacteria have a profound effect on the global environment, from the cycling of greenhouse gases to the availability of minerals and nutrients in the soil. We are interested in how these processes work on a molecular level through the action of enzymes expressed by the bacteria. In order to study these enzymes we employ a broad variety of techniques across the breadth of the science faculty; from spectroscopic methods such as electron paramagnetic resonance in the Biophysical suite in Chemistry to the culturing of micro-organisms in the Wolfson Fermentation Suite in Biology. Our group is based in a well furnished laboratory on floor 2 of BIO, where we share laboratory space and equipment with Prof. Richardson, Dr. Bowater, Dr. Hemmings and Dr. Watmough.
