Postdoctoral positions in systems/computational neuroscience at the University of Pennsylvania The Geffen Laboratory of Auditory Coding at the University of Pennsylvania ( http://www.med.upenn.edu/hearing ) has an opening for an experimental and a computational neuroscience postdoctoral fellow positions. We are looking for energetic, talented, friendly, enthusiastic and creative researchers who have recently completed or are about to complete their PhD. Qualifications: experience in systems, computational or molecular neuroscience methods; excellent quantitative skills and proficiency or willingness to learn scientific programming, such as Matlab or python. Our laboratory seeks to deepen our understanding of neuronal circuits and dynamics of neuronal populations contributing to auditory perception and learning. We use state-of-the-art methods including two-photon imaging of Calcium activity in behaving, head-fixed rodents, large-scale electrophysiological chronic and acute recordings, optogenetic, pharmacological and behavioral techniques, in combination with computational modeling and theoretical work. Projects underway in the laboratory include: investigating intra-cortical and subcortical circuits supporting auditory adaptation to statistical regularities of sounds; identifying neuronal circuits for hearing in the presence of noise and in complex acoustic environments; unraveling neuronal circuits controlling learning-driven changes in auditory perception. The Geffen Laboratory is a creative, productive and collaborative group, and the postdoctoral fellows will have many opportunities to interact and collaborate with members of our and other laboratories across the Penn campus and beyond. We are part of the Hearing Research Center, the Computational neuroscience initiative (https://cni.upenn.edu/) and the Mahoney Institute of Neurosciences (http://www.med.upenn.edu/ins/).
