Areas of interest: Protein coding genes represe130902_fig4_rnaseP_leader_track_webpage_final2_0.jpgnt approximately 2-3% of the total human genome, yet transcriptome mapping has recently revealed that at least 76% of the human genome is transcribed into RNA. Although the majority of our genome remains poorly understood, it is now clear that RNA molecules play a central role, coordinating intertwined layers of regulation that extend far beyond its role as a messenger. RNA is ideally suited to orchestrate this biological diversity because it is the only macromolecule that can both carry genetic information and perform chemical reactions by acting as an enzyme. We are currently at a fascinating frontier of RNA discovery and are only beginning to comprehend the 'other' 76% of the genome, how tertiary RNAs function in biology, and how RNA molecules interact with macromolecular protein complexes.

 We investigate the function and conformational dynamics of RNA-protein (RNP) interactions involved in key biological processes, from chromatin regulation to post-transcriptional gene regulation. We are interested in:

2) Defining specificity and recognition during transfer RNA processing

3) And unraveling new mechanisms of RNA-chromatin interactions

  We utilize structural biology tools and transcriptome-wide approaches to decipher key interactions at the RNA-protein interface and explore how these RNAs might be therapeutically targeted.
