Position Summary

The Ghanbarpour Laboratory in the Department of Biochemistry and Molecular Biophysics at WashU Medicine is seeking a highly motivated Research Specialist to join our interdisciplinary research program.

Our lab investigates how bacteria and human mitochondria maintain homeostasis and respond to stress and environmental challenges. A central focus of our research is uncovering the molecular mechanisms of ATP-dependent AAA+ proteolytic machines, both soluble and membrane-spanning, and their accessory factors in bacterial and mitochondrial systems. We study how these complexes assemble, achieve substrate specificity, and promote bacterial recovery from antibiotic stress, environmental changes, and pathogen attack. These efforts integrate cryo-EM and cryo-ET structural biology, biochemical and cellular assays, and mass spectrometry.

The lab also explores bacterial defense mechanisms against bacteriophage infection, including the deployment of innate immune strategies that enable survival during phage attack. Another major focus of our research is protein engineering and the development of new molecular tools based on these systems.

In this role, you will receive extensive hands-on training in cryo-EM sample preparation and data analysis, heterogeneity analysis tools, mass spectrometry, membrane biology, biochemistry, and cellular assays. The Ghanbarpour Laboratory and WashU Medicine provide state-of-the-art infrastructure for structural biology, biochemistry, and mass spectrometry, along with a highly collaborative research environment.

Provides critically complex research and experimentation for department/s allowing the advancement of scientific analysis and discovery. Serves as a subject matter expert offering support, training and guidance relative to the discipline/area. May participate and or present on the research developed, or the established work of those within the department.

The position is supported by NIH grant R35GM160328, the Longer Life Foundation, the Siteman Cancer Center Catalysts Award, and Washington University startup funds.
