Dr. Ying Liu received her medical degree from China Medical University in China and completed her residency and then worked as an attending physician in Neurology at the Dalian Medical University. She received her PhD degree in neuroscience at the Yamaguchi University School of Medicine in Japan. After finishing her PhD program, she was promoted to Assistant Professor in the Department of Neuroscience in Japan. She also pursued additional clinical training in the Department of Neurology at the Juntendo University School of Medicine in Tokyo, Japan. In order to broaden her exposure to transgenic models of neurodegenerative disease, she finished her postdoctoral fellow training in the Division of Neuropathology in Johns Hopkins University School of Medicine. Now as an assistant professor in the Cutaneous Nerve Laboratory of Neurology at Johns Hopkins, her focus is on evaluation of autonomic nerve fiber densities in skin biopsies and study the mechanism of fiber degeneration and regeneration in neurodegenerative disease.

Her expertise includes: Investigating the risk factors influencing autonomic fiber degeneration in human and experimental animal models. Dr. Liu's continuing work seeks to deepen the understanding the mechanisms of neuropathy using genetic model systems. Her studies involve developing the biomarker for cardiac autonomic neuropathy and age-related neurodegenerative diseases and studying the potential therapeutic strategy for diabetic neuropathy as well as chemo-therapy induced neuropathy.
