Douglas Paul Wiens is a Canadian statistician
Statistician
A statistician is someone who works with theoretical or applied statistics. The profession exists in both the private and public sectors. The core of that work is to measure, interpret, and describe the world and human activity patterns within it...

Wiens earned a B.Sc. in mathematics
Mathematics
Mathematics is the study of quantity, space, structure, and change. Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity...

. As part of his work on mathematical logic, in connection with Hilbert's tenth problem
Hilbert's tenth problem
Hilbert's tenth problem is the tenth on the list of Hilbert's problems of 1900. Its statement is as follows:Given a Diophantine equation with any number of unknown quantities and with rational integral numerical coefficients: To devise a process according to which it can be determined in a finite...

, Wiens helped find a diophantine formula for the primes: that is, multivariate polynomial with the property that the positive values of this polynomial, over integer arguments, are exactly the prime number
Prime number
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example 5 is prime, as only 1 and 5 divide it, whereas 6 is composite, since it has the divisors 2...

Wiens was editor-in-chief of The Canadian Journal of Statistics from 2004 to 2006 and program chair of the 2003 annual meeting of the Statistical Society of Canada. Along with the Ford award, Wiens received The Canadian Journal of Statistics Award in 1990 for his paper "Minimax-variance L- and R-estimators of location". In 2005 he was elected as a Fellow
Fellow
A fellow in the broadest sense is someone who is an equal or a comrade. The term fellow is also used to describe a person, particularly by those in the upper social classes. It is most often used in an academic context: a fellow is often part of an elite group of learned people who are awarded...
