Lab Opportunities

The research mission of the Mao Lab is to gain mechanistic understanding of the neural circuitry underlying motor control and sensori-motor integration in both normal and motor deficient animals. We value high quality science, collaboration and career development for young scientists. RO1 funded postdoctoral fellow positions are currently available. We also encourage graduate students and undergraduate students who are excited by our research to contact us. Please email Tianyi Mao () with any inquiries.

Striatal cortex axonal projectionsA Comprehensive Thalamocortical Projection Map at the Mesoscopic Level

The Mao Lab used modern viral tracing techniques and high-speed imaging to label thalamic projections and image their cortical targets from 75 brains with 254 injections. A comprehensive thalamocortical projection map, with a quantitative description of the thalamic origin of 19 cortical targets is presented.

Current Lab Members

Tianyi Mao, PhDTianyi Mao, Assistant Scientist and Principal Investigator

After earning her BS in Biological Science and Biotechnology at Tsinghua University in Beijing, China in 1997, Mao received her PhD 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. Mao was appointed as an assistant scientist at the Vollum Institute in September 2010.


Jeannie HunnicuttBarbara Jeannie Hunnicutt, Graduate Student

Jeannie is currently a graduate student in the Neuroscience Graduate Program. She earned her BS in Cell Biology & Neuroscience at Montana State University where she studied neuronal coding of working memory and peripheral nervous system development. Jeannie is characterizing the functional circuitry of the basal ganglia. She was recently awarded a National Science Foundation Graduate Research Fellowship as well as a Tartar Research Fellowship. Outside of the lab, Jeannie is involved in science education as a volunteer in the Life Lab at Oregon Museum of Science and Industry (OMSI).


Maozhen QinMaozhen Qin, Lab Manager

Maozhen obtained a bachelor's degree in nursing in China and has been working as a research assistant since 2008. She joined the Mao lab in 2011 where she quickly became the "go-to" person for genotyping, culturing slices, performing animal surgeries, and maintaining the inventory of lab supplies. Outside of work, Maozhen enjoys camping and hiking.
