A postdoctoral position is available immediately to study the structure and function of actin cytoskeleton dynamics. The actin cytoskeleton is a vast area, involving actin-binding proteins, signaling proteins, cytoskeleton scaffolding and membrane binding proteins. Most of the projects deal with protein complexes and involve large-scale protein expression and purification, biochemical and biophysical characterization and protein crystallography. Potential candidates should have a recent Ph.D. in biochemistry or biophysics. We offer competitive salary and benefits and outstanding opportunities for career development.
