Biography

Hai Zhang, Ph.D., is a Project Scientist in the Department of Anatomy and Neurobiology at the University of California, Irvine. Zhang received a Ph.D. in Pharmacology from Tongji Medical College, Huazhong University of Science and Technology in Wuhan, China. His research focuses on neural circuit mechanisms underlying neurological diseases, including Alzheimer's disease, depression, and pain modulation, using techniques such as viral tracing, in vivo structural and functional imaging, and behavioral studies in animal models.

Zhang's work spans multiple areas of neuroscience, from studying hippocampal neurogenesis in multiple sclerosis models to investigating spatial encoding deficits in Alzheimer's disease. His recent research has examined how acupuncture produces analgesic effects through specific brain pathways, identifying a retrosplenial cortex-anterior pretectal nucleus circuit that mediates acupuncture-induced analgesia. He has also investigated how interactions between erythrocytes and brain endothelial cells induce microglial responses and cerebral microhemorrhages, and how spatial mapping deficits in the hippocampus precede memory impairments in Alzheimer's disease mouse models.

Before joining UC Irvine in 2019, Zhang held research positions at Cleveland Clinic's Lerner Research Institute, where he studied hippocampal newborn neuron circuits in seizure and multiple sclerosis models, and at institutions in China including Tongji Medical College and the Shanghai Institute of Materia Medica, Chinese Academy of Science, where he worked on drug development for Parkinson's disease and depression. Zhang is a member of the Society for Neuroscience and has received research funding including a Youth Scientists Fund from the National Natural Science Foundation of China.
