Dr T Barraclough  No more applications being accepted  Funded PhD Project (European/UK Students Only)

About the Project

Supervisors: Prof. Tim Barraclough, Prof. Gary Frost, Prof. Glenn Gibson, Imperial College London, Department of Life Sciences (Silwood Park campus), with Department of Medicine (Hammersmith), and the University of Reading (Department

Duration: 1 + 3 years, the first year comprising an MRes programme.

Requirements: You should hold, or realistically expect to obtain, at least an Upper Second Class Honours degree or equivalent. You should have a strong academic background in biological or mathematical sciences.

Project outline: Gut bacteria play a vital role in human digestion and protection from disease, yet understanding of how these communities influence host function is limited, and has been reliant on experiments on rodents. This project will devise new in vitro and in silico models to replace the use of rodents and to increase understanding of interactions between gut bacterial diversity and human cell function, focusing on the fermentation of fibre and its effects on human cells. The project aims to understand the evolutionary and ecological dynamics of gut bacterial communities and their interactions with the host, then to apply that knowledge to managing impacts on human health. You will work at the interface of microbial ecology and evolution, medicine and nutritional sciences. You will learn a range of techniques in microbiology, evolutionary ecology, molecular biology, metabolomics, genomics, mathematical modeling and statistics.

Eligibility: UK nationals, EU nationals who have spent at least 3 years prior to the application resident in the UK. Non-UK residents might be considered if the research organization can demonstrate a shortage of high-quality UK candidates.

To apply: Please send a CV and a covering letter explaining why you are interested and what skills and abilities you could bring to the studentship to Tim Barraclough ([Email Address Removed]) by the 16th March 2012.

Career overview

Tim Barraclough is a Visiting Professor in the Department of Life Sciences at Silwood Park, part of the Faculty of Natural Sciences at Imperial College London. His research interests centre on the evolution of species diversity, exploring questions such as why life evolves into distinct species, the mechanisms that shape speciation and adaptive divergence, and the adaptive causes and consequences of species diversity. His work integrates theoretical frameworks with experimental, molecular, genomic, and field approaches across a variety of organisms. Barraclough''s research focuses particularly on the evolutionary dynamics of microbial communities and includes statistical methods for identifying units and mechanisms of diversification, as well as the evolutionary genomics of bdelloid rotifers. He has contributed significantly to the understanding of evolutionary dynamics and speciation processes.
