About us

Our research group is interested in understanding how RNAs change their structures in order to perform function. Until recently, only snapshots of molecules could be observed, hiding their mode of operation. We employ Nuclear Magnetic Resonance (NMR), and other biophysical techniques, to investigate the molecular mechanism of RNA function. When function of these molecular machines becomes apparent, it also provides a variety of unique new drug targets. The lab develops methods in NMR and RNA biochemistry to address these questions. Current projects include viral, bacterial and eukaryotic regulatory RNAs, e.g. microRNAs, ribosomal RNAs or RNA from HBV.


Congrats on your travel grants!

After 2 years of Covid and reduced travel, it’s great to be able to go to courses and conferences again! So a big thanks to KI and EUROMAR for allocating travel grants to Julian, Rubin, Magda and Joanna to allow them to go to the Netherlands, Switzerland and the US this year.

Goodbye Elnaz

Elnaz Banijamali is now leaving us after three years for new adventures in the Imig lab at Max Planck Institute in Dortmund. Wish you all the best!

Congrats Dr. Hannes!

Congratulations to the talented Dr. Feyrer! Hannes has also contributed to our lab as lab manager during his PhD, protected the lab from RNases! He worked on developing new methods for RNA production and in-cell NMR.

Frédéric Allain gives a talk at KI

The opponent for the defense of Hannes Feyrer’s thesis, Frédéric Allain, gives a talk at KI Thursday the 28th of April at 3 pm titled “Structural investigation of RNA binding proteins and phase separation in the context of the neuromuscular diseases ALS”

Farewell Natalia!

Natalia Galindo Riera joined Matthew Woods lab in University of Oxford as a part of Margarita Salas fellowship she granted from genetic department of Universitat de Valencia. We will miss you!
