Postdoctoral position in X-ray crystallography of functional complexes of ribosomes available beginning in Fall 2008. This project is aimed at solving the structures of ribosomes trapped in intermediate states of the translational cycle, containing translation mRNA, tRNAs, translation factors, etc. At the same time, we are working to improve the resolution of ribosome crystals (presently at 3.2A). This is a demanding and challenging project for a recent Ph.D. with a strong background in macromolecular crystallography. Supported by grants from the NIH, NSF. Excellent research environment with 4 structural biology groups, 8 RNA groups, within close driving distance of ALS and SSRL.
