[ccp4bb] Postdoctoral Position at NIH — Structures, Interactions and Mechanisms of Noncoding RNAs and RNPs.
Dear Colleagues, We are looking for a new member to join our group at the Laboratory of Molecular Biology at NIDDK, in NIH’s main campus in Bethesda, MD, USA. Set in an exciting and burgeoning field, the lab explores novel structures, mechanisms and interactions of large noncoding RNAs in bacterial, viral and eukaryotic gene regulation, stress response and antiviral immunity. We employ multidisciplinary tools such as RNA crystallography, single-particle Cryo-EM, small-angle X-ray scattering, fluorescence spectroscopy, chemical biology, and many other biochemical and biophysical tools. If you are interested or know of a suitable candidate, please contact me at jinwei.zh...@nih.gov. Detailed ad is below Thank you, -Jinwei Position Description: A fully funded postdoctoral position (up to 5 years) is available in the Structural Biology of Noncoding RNAs and Ribonucleoproteins Section, Laboratory of Molecular Biology (LMB), NIDDK, in NIH’s vibrant main campus in Bethesda, MD near Washington DC. The lab addresses a widening gap between the accelerated discovery and functional description of the noncoding transcriptome, and the lack of structural and mechanistic understanding of complex noncoding RNAs and RNPs. We seek a new member to join our diverse group to study gene-regulatory riboswitches, highly structured viral RNAs, long noncoding and circular RNAs and their complexes with other RNAs and immune proteins, etc. We develop and apply innovative technologies such as rational RNA design and engineering, RNA crystallography, RNA cryo-EM, XFEL, ultrafast SAXS/WAXS, single-molecule fluorescence, fluorescence lifetime, crosslinking-mass spec., etc. See https://www-mslmb.niddk.nih.gov/zhang/zhanglab.html and recent publications below for details: Bou-Nader C. et al., & Zhang, J.

A second project addresses how viral and cellular RNA structures differentially manipulate immune response protein activities such as dsRNA-binding PKR. We are delineating the structural hallmarks of self vs. non-self RNA, which are deterministic for activation or suppression of immune protein activity.
