statistic that generalizes a formula by Ronald A. Fisher (originally called the -formula, but now known as the Barndorff-Nielsen formula). He has jointly with David Cox written two influential books on asymptotic techniques in statistics. Since the mid-90s Barndorff-Nielsen has worked on stochastic models in finance (often with Neil Shephard) and turbulence, on statistical methods for the analysis of data from experiments in quantum physics, and has contributed to the theory of Lévy processes. Notable honors and positions held Barndorff-Nielsen is a member of the Royal Danish Academy of Sciences and Letters and of Academia Europaea. He has received honorary doctorate degrees from the Université Paul Sabatier, Toulouse and the Katholieke Universiteit Leuven. In 1993-1995 he was a very influential president of the Bernoulli Society for Mathematical Statistics and Probability. He was the editor of International Statistical Review in 1980-1987 and of the journal Bernoulli in 1994–2000. From 1 April 1998 to 31 March 2003 he was Scientific Director of MaPhySto (the Centre for Mathematical Physics and Stochastics), which was a centre devoted to advanced research and training in the fields of mathematical physics and stochastics, as well as some closely related areas. In 2001 he received the Humboldt Prize and in 2010 the Faculty Price from Faculty of Science, Aarhus University. Bibliography O. E. Barndorff-Nielsen, V. K. Gupta, Victor Pérez-Abreu, and E.
