Adrian John Baddeley (born May 25, 1955) is a statistical scientist working in the fields of spatial statistics,A. Baddeley, E. Rubak and R.Turner, "Spatial Point Patterns: Methodology and Applications with R", Chapman and Hall/CRC Press 2015. statistical computing, stereologyA. Baddeley and E.B. Vedel Jensen, Stereology for Statisticians, Chapman and Hall/CRC Press 2005. and stochastic geometry.
Life and career Baddeley was born in Melbourne, Australia and educated at Eltham High School there, and studied mathematics and statistics at the Australian National University (honours supervisor: Roger Miles) and the University of Cambridge (PhD supervisor: David George Kendall). He was elected a Junior Research Fellow at Trinity College, Cambridge in the second year of his PhD. Subsequently, he worked for the University of Bath (1982–85), the CSIRO Division of Mathematics and Statistics, Sydney (1985–88), the Centrum Wiskunde & Informatica, Amsterdam, the Netherlands (1988–94), the University of Western Australia (where he was Professor of Statistics from 1994 to 2010), CSIRO Division of Mathematics, Informatics and Statistics, Perth (2010–2012), and the Centre for Exploration Targeting at the University of Western Australia (2013–2014). He is now Professor of Computational Statistics at Curtin University.
Research Stereology Classical methods of stereology were limited by the requirement that the cutting plane be randomly oriented. Baddeley developed an alternative techniqueA.J. Baddeley, H.J.G. Gundersen, and L.M. Cruz-Orive. Estimation of surface area from vertical sections. Journal of Microscopy, 142:259-276, 1986 in which the cutting plane is "vertical" (parallel to a fixed axis, or perpendicular to a fixed surface) making it possible to apply quantitative microscopy to cylindrical core samples, samples of flat materials, and longitudinal sections.
Baddeley is a leading advocate of statistical ideas in stereology. With Cruz-Orive he demonstrated the role of the Horvitz-Thompson weighting principle and the Rao-Blackwell theorem in stereological sampling.
Spatial statistics Baddeley is one of the world leading specialists in point pattern analysis, a connection of stochastics and geometry applied to the analysis of (mainly) 2D point distributions in Euclidean space. He has developed statistical methodologies for analyzing the structure of spatial patterns of points, including methods based on survival analysis,A.J. Baddeley and R.D.
