Position SummaryThe Psychiatry and Neuronal Health group at Eli Lilly is seeking a highly motivated Postdoctoral Research Fellow to join an active in vivo pharmacology program studying reward, arousal, and stress-related neural circuitry. The successful candidate will apply circuit-level tools, including fiber photometry, microdialysis, and behavioral pharmacology models, to characterize neuromodulatory signaling relevant to CNS drug discovery.Key ResponsibilitiesDesign and execute in vivo experiments in rodent behavioral models relevant to CNS drug discovery, including chronic IV self-administration, extinction, and cue-induced reinstatement paradigmsPerform rodent survival surgeries: stereotaxic viral injection, IV catheter implantation, and fiber optic cannula placementPerform single- and dual-site in vivo fiber photometry recordings (genetically encoded calcium and/or neuropeptide biosensors) to characterize real-time circuit dynamics during behavior, including during cue-triggered reinstatement testingConduct in vivo microdialysis paired with LC/MS or immunoassay quantification to measure neurotransmitter/neuropeptide efflux across relevant brain nucleiApply circuit-dissection techniques to map projections and test causal sufficiency/necessity in the behaviors under studyPerform multiplex fluorescence and routine histological experimentsCharacterize sleep/arousal architecture (EEG/EMG) as relevant to project needsSupport processing and molecular analysis of human postmortem brain tissue, including coordination with external tissue repositoriesAnalyze and interpret multimodal datasets (behavioral, neurochemical, imaging, transcriptomic) using established computational pipelinesAuthor manuscripts for peer-reviewed publication and present findings at internal reviews and external scientific conferencesMaintain rigorous documentation, IACUC protocol compliance, and data integrity standardsRequired QualificationsPh.D. (or equivalent) in Neuroscience, Pharmacology, Behavioral Neuroscience, or a closely related field, completed within the last 1–3 years (or near completion)Hands-on experience with in vivo fiber photometry (calcium/neuropeptide sensor recording, signal processing, and analysis)Demonstrated expertise in rodent stereotaxic surgery, viral vector delivery, and fiber optic cannula implantationExperience with rodent operant/behavioral pharmacology models (IV self-administration, extinction, and/or cue reinstatement paradigms strongly preferred; IV catheterization experience a plus)Familiarity with in vivo microdialysis and downstream analytical quantification (HPLC/LC-MS or similar)Qualified applicants must be authorized to work in the United States on a full-time basis.
