Timothy (Tim) Poston (born 19 June 1945 in St Albans, Hertfordshire) is an English mathematician best known for his work on catastrophe theory. His 1972 Ph.D at the University of Warwick was directed by Christopher Zeeman on "Fuzzy Geometry". Less well known was his role as active founding member of COUM Transmissions performance group with Genesis P-Orridge. They studied at Hull University together. Tim Poston wrote texts and advised COUM on physics and maths 1968-1978.Tim Poston remains "Scientific Adviser" to P-Orridge to the present. His books on catastrophe theory and on differential geometry and relativity are still in print after a third of a century.
