Education:
1986-1990            B.S., Biochemistry, Nankai University, Tianjin, P.R. China
1994-1999            Ph.D., Molecular Neuroscience, Wayne State University, Michigan

Postdoctoral Training:
1999-2001            Rutgers University

Research Interests:
Spinal cord injury (SCI) and repair, microRNAs (miRNAs), neuronal reprogramming, neurodevelopment, glial development, neural stem/progenitor cells, cell transplantation.

My research is focused on miRNA-mediated mechanisms during CNS development and after SCI. In addition, I combine the in vivo reprogramming technology with miRNA biology to induce miRNA-mediated neuronal reprogramming from endogenous reactive glial cells for SCI functional repair. MiRNAs are small and chemically modifiable, which makes them ideal candidates for therapy as synthetic drug. In fact, some miRNAs are already in clinical trials. My long-term research interest is to understand mechanisms of CNS development and injury, and their therapeutic potentials to treat SCI with a focus on miRNAs.
