In 2017, NATCOR will be running week-long residential courses in Stochastic Modelling, Simulation and Combinatorial Optimisation. Although based in the UK, the courses are open to PhD students and post-docs from any country working in a relevant area, such as Operational Research, Statistics, Engineering, Computer Science or Quantitative Finance. Detailed descriptions of these courses, and information about registration and accommodation fees may be found on our website (http://www.natcor.ac.uk). Our courses are approved by the UK Research Councils and also by EURO (the European Association of Operational Research Societies). Professor Adam N.
