Experience with rodent models and one or more of the following is highly desirable: in vivo electrophysiology/EMG, respiratory physiology or whole-body plethysmography, locomotor or motor behavioral assessment, calcium imaging, viral vector approaches, optogenetics/chemogenetics, stereotaxic or spinal surgery, histology, microscopy, and quantitative data analysis. Designs and performs experiments to define respiratory and motor circuit function using approaches that may include whole-body plethysmography, diaphragm and other muscle EMG, neural electrophysiology, in vivo calcium imaging, viral circuit mapping, behavioral and locomotor assessment, and optogenetic/chemogenetic neuromodulation.
