Klaus Eyer is associate professor of biomedicine at Aarhus University, where he investigates how single-cell diversity and complexity shape immune responses and their outcomes. His lab develops high-resolution single-cell technologies to measure cellular function and phenotype within complex immune environments, capturing dynamic behaviors and revealing how complex immune outcomes emerge from individual cells with diverse functionality, metabolism, gene expression and plasticity—concepts that parallel variability and population dynamics in neural systems. More recently, Eyer’s work has expanded to explore diseases at the neuro-immune interface.
Eyer trained in pharmaceutical sciences and bioanalytics at ETH Zurich and completed postdoctoral work in microfluidics and single-cell analysis at ESPCI Paris, as well as a visiting fellowship in B cell immunology at the Institut Pasteur.
He coordinates the TRANSCEND doctoral network and actively engages in translational initiatives through patents, spinoffs, mentoring and teaching. At Aarhus University, he established doctoral courses on measurement and data translation, training the next generation of scientists to integrate fundamental research with clinical and biomedical translation.
