Title: Advances in Mendelian Randomization

Abstract: First, I will motivate the need for causal inference in contrast to observational correlations. In particular, I’ll describe the principle of an instrumental variable approach heavily applied in genetic research, termed Mendelian Randomization (MR). Next, I will show four extensions of this method to different settings/assumptions: (i) In-depth quantification and correction of the bias of the most popular MR method (IVW); (ii) Modelling genetic architecture simultaneously with bidirectional causal effects in the presence of a heritable confounder; (iii) Causal inference for composite trait type exposures; (iv) estimation of non-linear causal effects. I’ll finish with two applications to omics data: first, we link differential gene expression analyses with bi-directional causal effects and finally, I’ll touch on how causal effects of different omics layers are mediated.
