Biological Chemistry and Crop Protection
Rothamsted Research is the largest agricultural research centre in the United Kingdom and almost certainly the oldest agricultural research station in the world.
Its scientific research ranges from studies of genetics, biochemistry, cell biology and soil processes to investigations at the ecosystem and landscape scale. Rothamsted Research is now an independent research establishment undertaking research on behalf of BBSRC and other funders.
Further information on Rothamsted Research can be obtained from our website at: A scientist is required to join a multi-disciplinary team working on the genetic and semiochemical basis of tick resistance in cattle in Brazil. The successful applicant will work on the isolation and identification of tick semiochemicals from resistant cattle, and will undertake analysis of identified semiochemicals form cattle that have been selected for genome-wide association analysis.
Main purpose of job:
To undertake analytical chemistry studies on biological samples collected from cattle that differ in their tick load.
The extraction of biological samples collected from Brazilian cattle that differ in their tick load, the analysis of samples using high resolution gas chromatography/high performance liquid chromatography, and quantification of identified semiochemicals from cattle selected for genome-wide association analysis. The post holder will liaise closely with other members of the Chemical Ecology group at Rothamsted on structure elucidation, and will spend time in the laboratory of Dr Isabel Santos, University of Sao Paulo, facilitating the collection of biological samples from cattle, with continual monitoring and assistance throughout.
Rothamsted: Dr Mike Birkett (Line Manager, co-Principal Investigator), Professor John Pickett (co-Principal Investigator). Collaborations: Professor Stephen Bishop, Roslin Institute and Dr Isabel Santos, University of Sao Paulo.

Gastric Ulcers WHAT ARE EQUINE GASTRIC ULCERS? ‘Equine Gastric Ulcer Syndrome’ describes the erosion of the horse’s stomach lining, due to the prolonged exposure to the acid produced by the stomach. Gastric ulceration is a common, serious condition that can be fatal in foals and can also seriously affect an adult horse. Despite negatively affecting appetite, temperament and over
