Job Title: Postdoctoral Position on Ion Channel and Neuroscience at Johns Hopkins

Job Number: 54587

Location: Baltimore, US

Job Description

Postdoctoral opportunities are available immediately in the laboratory of Dr. Zhaozhu Qiu at Johns Hopkins University School of Medicine. The Qiu lab performs high-throughput functional genomic screens to discover and deorphanize novel ion channels and transporters. We employ a multi-disciplinary approach including patch-clamp electrophysiology, single-particle cryo-EM, single-cell RNA-Seq, imaging, mouse genetics and behavioral study to reveal the gating and regulatory mechanisms of the novel ion channels, and to elucidate their physiological function with a focus on the brain. We are also working to translate fundamental discoveries and target them for devastating neurological disorders (such as Alzheimer’s disease, glioma, and neuropathic pain). More information about the Qiu lab can be found at

Experience in the broad fields of membrane protein (structural biology, biochemistry, and electrophysiology), neuroscience (neuron, microglia, and astrocyte), and neurodevelopmental and neurological diseases is preferred, but not required. The candidates will join a stimulating and collaborative research environment. Strong mentorship will be provided to help them achieve their career goals. The Baltimore/Washington D.C. region also offers rich professional and living opportunities. To apply please provide a cover letter (with a brief statement of prior experience and research interests), CV, and contact information for 3 references to Dr. Zhaozhu Qiu at [Please click the Apply button for the link or email].
