Sheila Macdonald Bird OBE FRSE FMedSci is a Scottish biostatistician whose assessment of misuse of statistics in the British Medical Journal (BMJ) and BMJ series ‘Statistics in Question’ led to statistical guidelines for contributors to medical journals. Bird's doctoral work on non-proportional hazards in breast cancer found application in organ transplantation where beneficial matching was the basis for UK's allocation of cadaveric kidneys for a decade. Bird led the Medical Research Council (MRC) Biostatistical Initiative in support of AIDS/HIV studies in Scotland, as part of which Dr A. Graham Bird and she pioneered Willing Anonymous HIV Surveillance (WASH) studies in prisons. Her work with Cooper on UK dietary bovine spongiform encephalopathy (BSE) exposure revealed that the 1940–69 birth cohort was the most exposed and implied age-dependency in susceptibility to clinical vCJD progression from dietary BSE exposure since most vCJD cases were younger, born in 1970–89. Bird also designed the European Union's robust surveillance for transmissible spongiform encephalopathies in sheep which revolutionised the understanding of scrapie.

John Stewart Shawe-Taylor is Director of the Centre for Computational Statistics and Machine Learning at University College, London (UK). His main research area is statistical learning theory. He has contributed to a number of fields ranging from graph theory through cryptography to statistical learning theory and its applications. However, his main contributions have been in the development of the analysis and subsequent algorithmic definition of principled machine learning algorithms founded in statistical learning theory. This work has helped to drive a fundamental rebirth in the field of machine learning with the introduction of kernel methods and support vector machines, including the mapping of these approaches onto novel domains including work in computer vision, document classification and brain scan analysis. More recently he has worked on interactive learning and reinforcement learning. He has also been instrumental in assembling a series of influential European Networks of Excellence. The scientific coordination of these projects has influenced a generation of researchers and promoted the widespread uptake of machine learning in both science and industry that we are currently witnessing. He has published over 300 papers with over 42000 citations. Two books co-authored with Nello Cristianini have become standard monographs for the study of kernel methods and support vector machines and together have attracted 21000 citations.
