Biography

Dr. Liu joined the Center for the Study of Itch at Washington University School of Medicine in 2012, after she finished her postdoctoral training in the Department of Neuroscience, the Johns Hopkins School of Medicine. Using genetically modified mouse models and a combination of molecular, cellular, and behavioral techniques, Dr. Liu identified several novel itch receptors mediating non-histaminergic itch. Her discoveries not only reveal a novel mechanism for itch perception, but also open the door to studying both the cause and mechanism of chronic itch. Dr. Liu’s future research interests include understanding how primary sensory neurons detect itch-inducing stimuli, how itch signals are encoded and transmitted in the nervous system, and the molecular and neural pathogenesis of chronic itch conditions. Dr. Liu has been invited to lecture at many universities. She is also the recipient of 2011 Helen B. Taussig Award and 2015 Pew Biomedical Scholar Award.
