Open Postdoctoral position, faculty mentor Ruth Huttenhain

The Huttenhain Lab at Stanford University is looking for postdoctoral fellows to study mechanisms of intracellular signal integration through G protein-coupled receptors (GPCRs) using cutting edge mass spectrometry-based proteomics, functional genomics, and molecular biology techniques. Applicants with expertise and interest in either (1) mass spectrometry-based proteomics and/or CRISPR-based functional genomics, (2) molecular and cell biology including neuroscience, GPCRs or related techniques, and/or (3) computational biology are encouraged to apply.
Lab overview
The communication between cells and their environment depends on decoding of extracellular cues into intracellular signaling cascades that are integrated through dynamic and context-specific networks driving the cellular responses. Given the complexity and dynamic state of signaling networks, the current understanding of their constituents and how they are spatiotemporally regulated in the cell as a result of a specific input is incomplete.
The Huttenhain lab (https://med.stanford.edu/profiles/ruth-huttenhain ) in the Molecular & Cellular Physiology Department (https://med.stanford.edu/mcp.html ) at Stanford University, studies mechanisms of intracellular signal integration through G protein-coupled receptors (GPCRs), the largest family of membrane receptors mediating most of our physiological responses to hormones, neurotransmitters and environmental stimulants. We employ an interdisciplinary approach to probe, model, and predict how signaling network dynamics translate extracellular cues sensed by GPCRs into specific phenotypic outputs. Developing quantitative proteomics approaches to capture the spatiotemporal organization of signaling networks and combining these with functional genomics and molecular biology techniques to study their impact on physiology, we aim to better understand GPCR signaling and to provide a solid foundation for the design and testing of novel therapeutics targeting GPCRs with higher specificity and efficacy.
