Symposium: On the Thursday morning (26th November), there will be a half-day symposium that is open to course participants. It is not a formal part of the course, and it will also be open to non-course attendees. The aim of the symposium will be to present more cutting-edge methodology for Mendelian randomization that is either still under development, or not relevant to all applications of Mendelian randomization (examples of the latter would be multivariable Mendelian randomization and methods for estimation of non-linear causal relationships).
