Congratulations to Professor Alan Welsh, who has been recognised internationally as having made highly original and insightful contributions to the advancement of statistics. 

Professor Welsh has developed useful new methodology, derived the properties of these and other methods and clarified relationships between different statistical methods, all in a particularly wide variety of problems. He has developed innovative new models for count data with many zeros and compositional data, including for longitudinal and clustered forms of these data. He has made important contributions to inference, robustness, the bootstrap and model selection for mixed models.
