Dr. Ye is the recipient of numerous professional honors, including the Distinguished Scientist Award from the Sontag Foundation (2003) and American Cancer Research Scholar (2004), and he is also one of the semi-finalists for Keck Foundation (2004). He has published approximately 220 papers with numerous papers in top journals including: Cell, Nature, Nature Medicine, Nature Cell Biology, Nature Neuroscience, Neuron, Mol. Cell, EMBO J, PNAS etc. His lab mainly focuses on neurotrophine-mediated neuronal survival singaling pathway and their role in neurodegenerative diseases. He identified numerous novel TrkA and TrkB agonists. These small molecules exhibit potent neurotrophic effect and display great therapeutic potentials for various neurological diseases including Alzheimer’s disease (AD). Most recently, he found that AEP acts as a novel delta-secretase that cleaves both APP and Tau and mediates AD pathogenesis. It is an innovative drug target for treating AD. His lab has identified the small molecular inhibitors that display promising therapeutic efficacy toward AD.
