This position is ideally suited for candidates with a strong background in neuroscience, sleep and circadian science, aging, cognitive health, nursing, biomechanics, rehabilitation sciences, biomedical engineering, epidemiology, data science, biostatistics, or related fields, with experience conducting hypothesis-driven clinical, translational, or computational research in human populations. This work integrates large-scale clinical datasets, multimodal physiological measures (e.g., sleep, actigraphy, cognition, mobility/gait, gut microbiome/biomarkers), and advanced computational and statistical approaches to advance our understanding of perioperative brain vulnerability, resilience, and recovery.
