Biology of Non-Coding RNA

The major focus of my lab is gene regulation by small RNAs. Small RNAs are regulatory non-coding RNAs that can have significant effects on translation, RNA stability and on chromatin. We use transgenics, genetics and biochemical and structural approaches to unravel the molecular pathways that are steered by small RNAs. We especially study embryogenesis and germ cell development, using C. elegans and zebrafish model systems.

We are currently working to understand how certain transcripts are selected to be turned into small regulatory RNAs, while others are not. This is crucial to understand, since these molecules fully set the target specificity of the regulatory processes. In addition, we work on understanding how small RNA pathways connect to other aspects of the cell's gene-regulatory programmes, including those active during germ cell specification and differentiation. Finally, an important current aim is to understand how phase separation acts to compartmentalise different steps in small RNA mediated gene regulation.
