Richard David Gill (born 11 September 1951) is a mathematician born in the United Kingdom who has lived in the Netherlands since 1974. As a probability theorist and statistician, Gill is known for his research on counting processes and survival analysis, some of which has appeared in an advanced textbook. He is the chair of mathematical statistics at Leiden University. Gill is also known for his pro bono consulting and advocacy on behalf of victims of incompetent statistical testimony, including a Dutch nurse who was wrongfully convicted and jailed for six years. ==Biography== He studied mathematics at the University of Cambridge (1970–1973), and subsequently followed the Diploma of Statistics course there (1973–1974). Marrying a Dutch woman, he moved to the Netherlands where he worked from 1974 to 1988 at the Mathematical Centre (later renamed ''Centrum Wiskunde & Informatica'', or CWI) of Amsterdam. In 1979, Gill obtained his PhD with the thesis ''Censoring and Stochastic Integrals'', which was supervised by Jacobus Oosterhoff of the Vrije Universiteit, which awarded the doctorate. Gill spent Autumn 1980 at the Statistical Research Unit at the University of Copenhagen. Gill continued to collaborate with Danish (and Norwegian) statisticians for ten years, helping to write the book ''Statistical models based on counting processes'', which is often referred to as "ABGK" (for the authors Andersen, Borgan, Gill, and Keiding). In 1983 he became the head of the Department of Mathematical Statistics at CWI. In 1988 he moved to the Department of Mathematics of Utrecht University. Gill became the chair in mathematical stochastics—this chair represented the three mathematical sciences of mathematical statistics, probability theory, and operations research. His PhD students include Sara van de Geer and Mark van der Laan.〔 In 2006, he moved to the Department of Mathematics at Leiden University, where he became the chair of mathematical statistics. Since then, he has conducted statistical research in the theory of quantum information and in biostatistics. He has also worked on survival analysis, semiparametric models, causality, missing data, machine learning, and statistics in image analysis. Gill also publishes on the foundations of several mathematical sciences: the foundations of statistics, of probability, of mathematics, and of quantum physics. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Richard D.
