Genetics and genomics of Streptococcus pneumoniae Angela Brueggemann's main focus is using high-throughput genotyping and whole genome sequencing techniques and unique collections of isolates to understand pneumococcal evolution, especially evolutionary changes related to antimicrobial and vaccine selective pressures.

Professor Townsend tells us about lessons to be drawn from the history of immunology in Oxford, from 1979 onwards, until his current research on active and passive immunity to influenza. All these developments happened in Oxford because the atmosphere was right, open, researchers were encouraged to explore, and there was an enthusiasm in a great environment. Experiments and discoveries were made possible by the very open attitude of the supervisors at the time, telling their team that they they could do anything they wanted.

Professor Peter Donnelly tells us how genetics helps us to understand common diseases and develop new drugs. Understanding which variations in our DNA affect susceptibility to diseases can provide new insights into the disease process and lead to new treatments. Professor Peter Donnelly leads large collaborative human genetic studies, and his group develops and applies statistical methods to extract maximal information from the large datasets generated by genomic studies.

Dr Trudie Lang tells us how the Global Health Network facilitates collaboration and resource sharing. Clinical trials establish the evidence base for prevention and treatment of disease and are critically important in the field of Global Health. Dr Trudie Lang leads the Global Health Clinical Trials group, which aims to promote and improve the conduct of non-commercial clinical research across all diseases in resource-poor settings.

Professor Nick White talks about the future of artemisinin and other drug therapies for malaria. Malaria kills more than half a million people every year. Following a number of groundbreaking clinical trials, Professor Nick White and his Thailand team successfully demonstrated the effectiveness of artemisinin drug therapy for malaria in adults, children and infants. He also pioneered artemisinin combination therapy, the first-line treatment for malaria worldwide.

Professor Chris O'Callaghan tells us about the role of our immune system in vascular disease. The accumulation of fat in the arteries, such as cholesterol, can cause a thickening of the artery wall known as atherosclerosis. Professor Chris O'Callaghan is researching the role of the innate immune system in atherosclerosis to better understand immune responses to vascular disease. This may lead to improved treatments.

Dr Najib Rahman talks about his research on respiratory medicine. The Pleura are thin membranes that cover the surface of the lungs. Dr Najib Rahman specialises in areas of respiratory medicine including pleural disease and the conduct and analysis of respiratory trials. Dr Rahman is currently conducting clinical studies in malignant and infectious pleural disease, and is Clinical Director of the Oxford Respiratory Trials Unit.

Professor Jonathan Flint talks about his research on psychiatric genetics. It is now known that genetic variants can form the basis of psychiatric disorders, such as depression and anxiety. Professor Jonathan Flint is investigating the genetics behind psychiatric disorders, in particular the origins of stress-related conditions, such as anxiety and depression, for which we have relatively ineffective treatments.

Professor Stefan Knapp tells us how the development of chemical probes helps us to find new drugs. The role of proteins in cellular signalling and disease is best studied through the development of highly specific chemical inhibitors, which can serve as a tool molecule for functional studies. Professor Stefan Knapp works to determine the structure of protein molecules to understand their regulation and to aid the design of selective inhibitors that can be developed further into efficient drugs

Dr Sumi Biswas talks about the development of a vaccine aimed at the mosquito stage of the malaria parasite cycle. Malaria transmission-blocking vaccines aim to induce immunity against the parasites that infect mosquitoes. Such vaccines will prevent malaria transmission on a wider scale, focusing on the community rather than the individual. Dr Sumi Biswas is working on the development of transmission-blocking vaccines to prevent the spread of malaria.
