ESGI (European Study Group with Industry) is Europe's leading workshop for interaction between mathematicians and industry.
These week long workshops have occurred annually since 1968 (previously as the Oxford Study Groups with Industry) and attract leading mathematicians to work on industrial problems.
Problem areas include those involving heat and mass transfer, fluid flow, granular materials, electric fields, financial derivative pricing and processes amenable to modelling by continuum mechanics, but there in principal no limitations in the types of mathematics used in these workshops.
