Regulation of cell fate and gene silencing by liquid-liquid phase separation

The major focus of my lab is gene regulation by small RNAs. Small RNAs can have relatively minor effects on translation (in the case of miRNAs) to full-blown shutdown of loci at the transcriptional level (piRNAs). We use transgenics, genetic screens and biochemical and structural approaches to unravel the molecular pathways that are steered by small RNA guides in embryonic and germ cell development.

We are currently working to understand how piRNA responses can be initiated de novo and how and when a transient small RNA-mediated response can be transformed into a stably inherited response. In addition, we will start to 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.
