Welcome to the Marchfelder laboratory

Investigation of the RNA metabolism in halophilic Archaea

Research projects

We are interested in the RNA metabolism of halophilic archaea. Currently we are working on the following projects using the halophilic archaea Haloferax volcanii, Natrialba magadii, Haloterrigena turkmenica and Halorubrum lacusprofundi:

CRISPR-Cas functions beyond defence (SPP2141)

Small regulatory RNAs


Small proteins

The prokaryotic immune system CRISPR-Cas (FOR1680)





Head of the research group:


We offer exchange visits with Prof. Dr. Thorsten Allers laboratory, University of Nottingham.

The 2020 Nobel Prize in Chemistry has been awarded to Emmanuelle Charpentier and Jennifer Doudna for the development of a method for genome editing. (CRISPR-Cas)
