Tianyi Mao Ph.D.

Tianyi Mao is a scientist in the Vollum Institute at OHSU. After earning her B.S. in Biological Science and Biotechnology at Tsinghua University in Beijing, China in 1997, she received her Ph.D. in Neuroscience from the Johns Hopkins University School of Medicine in 2005. She did postdoctoral research at the Cold Spring Harbor Laboratory and then at the Howard Hughes Medical Institute's Janelia Farm Research Campus. Dr. Mao joined the Vollum Institute in 2010 and was promoted to scientist in 2017.

The research mission of the Mao Lab is to examine the functional connectivity within basal ganglia and its interaction with cerebral cortex and thalamus. The basal ganglia are critical for many fundamental brain functions, such as movement control and decision-making. Dysfunction of the basal ganglia contributes to the pathophysiology of many neurodegenerative diseases, most notably Parkinson’s disease and Huntington’s disease.
