Postdoctoral position in cryo-EM and translation regulation ‒ from bacteria to neurons

 

Korostelev Lab, University of Massachusetts Medical School

 

We study how the ribosome interacts with numerous cellular components to achieve high accuracy and efficiency of gene expression. We’d like to understand the key roles of translation and ribosomes in: (1) Neurodevelopment and neurodegenerative diseases; (2) Bacterial stress signaling and gene regulation (e.g. coupling with transcription); and other aspects of gene expression (https://www.umassmed.edu/korostelev-lab/). We use a range of approaches, including cryo-EM and biochemistry (see selected references below).

Our laboratory is housed at the RNA Therapeutics Institute, a vibrant and highly interactive research community: https://www.umassmed.edu/rti/about-the-rti/faculty-members/.  Our colleagues are interested in nearly all aspects of RNA biology, from small to large RNAs to RNA chemistry and therapeutics development.
