Meiyu Xu

Associate Research Scientist in Psychiatry

Biographical Info

Meiyu has been a postdoc in the laboratory since 2009. Her focus has been studying the cellular and molecular mechanisms underlying the pathophysiology of Tourette syndrome (TS) using virus tools and mouse models. She received a grant award in 2011 from the Tourette Syndrome Association.

Meiyu's Ph.D. researches focused on the regulation of food intake and growth regulation by some endocrine hormones, e.g. prepro-orexin (OX), PACAP-related peptide, preprosomatostatin, etc.
