Background

Dr Joe Gallagher is a Project Initiator in the Biorenewables and Environmental Change Division, IBERS, AU. He is an expert in the area of grass carbohydrates and the principle aim of his research is to understand carbohydrate metabolism in grasses to improve crop performance and increase substrate supply for a range of down-stream applications including biorefining. Dr Gallagher also has experience in the processing and fermentation of feedstocks to a range of products. He co-coordinates the fermentation group within the Biorenewables and Biorenewables Programme, which is involved in determining fermentation quality of our extensive germplasm collections and investigating how changes in chemical composition resulting from feedstock breeding programmes affect fermentability. He is also involved in optimising bioconversion processes through the use of recombinant enzymes from plants, fungi and bacteria as well as genetic manipulation of fermenting organisms. Dr Gallagher leads the Bio-conversion and Biorefining Group, working on the breakdown of complex carbohydrates and the isolation and production of both fine and bulk chemicals. He is employed on a UK BBSRC strategic programme and is part of the BBSRC Bioenergy Centre (BSBEC). He is also a project leader in the Biorefining Centre of Excellence ‘BEACON’. Dr Gallagher lectures on biorenewables (AU, MSc course) and is project manager and PI on a number of externally funded grants in the area of biorefining (e.g. http://www.grassohol.org).
