James Ritchie Norris is a mathematician
working in probability theory
and stochastic analysis. He is the Professor of Stochastic Analysis in the Statistical Laboratory, University of Cambridge.
He has made contributions to areas of mathematics connected to probability theory
and mathematical analysis
, including Malliavin calculus
, heat kernel estimates
, and mathematical models for coagulation
and fragmentation
. He was awarded the Rollo Davidson Prize in 1997.

where he graduated in 1981. He completed his D.Phil in 1985 at Wolfson College, Oxford
under the supervision of David Edwards. He was a Research Assistant from 1984–1985 at the University College of Swansea before moving in 1985 to a Lectureship at Cambridge University and a Fellowship of Churchill College, Cambridge
. He was appointed Professor of Stochastic Analysis in 2005. He is the Director of the Statistical Laboratory
, a trustee of the Rollo Davidson Trust. and co-Director of the Cambridge Centre for Analysis.
Mathematician
A mathematician is a person whose primary area of study is the field of mathematics. Mathematicians are concerned with quantity, structure, space, and change....
working in probability theory
Probability theory
Probability theory is the branch of mathematics concerned with analysis of random phenomena. The central objects of probability theory are random variables, stochastic processes, and events: mathematical abstractions of non-deterministic events or measured quantities that may either be single...

and mathematical analysis
Mathematical analysis
Mathematical analysis, which mathematicians refer to simply as analysis, has its beginnings in the rigorous formulation of infinitesimal calculus. It is a branch of pure mathematics that includes the theories of differentiation, integration and measure, limits, infinite series, and analytic functions...
, including Malliavin calculus
Malliavin calculus
The Malliavin calculus, named after Paul Malliavin, is a theory of variational stochastic calculus. In other words it provides the mechanics to compute derivatives of random variables....
, heat kernel estimates
Heat kernel
In the mathematical study of heat conduction and diffusion, a heat kernel is the fundamental solution to the heat equation on a particular domain with appropriate boundary conditions. It is also one of the main tools in the study of the spectrum of the Laplace operator, and is thus of some...
, and mathematical models for coagulation
Coagulation
Coagulation is a complex process by which blood forms clots. It is an important part of hemostasis, the cessation of blood loss from a damaged vessel, wherein a damaged blood vessel wall is covered by a platelet and fibrin-containing clot to stop bleeding and begin repair of the damaged vessel...
and fragmentation
Fragmentation (cell biology)
In cell biology, fragmentation is the breaking apart of cells or cell organelles into smaller parts. Fragmentation may serve as a normal function for the cell, but may also be the result of a disorder.-Function:...
