    Collapse Overview
    Over the past 10 years, I have worked in clinical orthopaedic surgery from emergency to rehabilitation in spinal disorders and related projects in Japan. During my PhD in bone biology and oncology, I received training in molecular biology techniques and statistical genetics/genomics and translation methodology. My doctoral dissertation investigated the gene expression profiles using cDNA microarray analysis in osteosarcoma samples, identifying the tyrosine kinase orphan receptor with ligand Wnt as a candidate therapeutic target for human osteosarcoma. In my postdoctoral fellow in Japan, I received training in pre-clinical spinal cord injury (SCI) research at the University of Zurich, and took part in a pilot study to evaluate a novel biomarker for the severity of SCI patients at the National Rehabilitation Center, gaining an interest in spinal cord research. In my postdoctoral fellow in US, my current research focuses on the cellular mechanisms of neuronal plasticity and functional recovery following traumatic central nervous system injury at UCSF Brain and Spinal Injury Center. I hope that our fruitful projects might serve as patients for allowing to acquire essential functions again leading to improved quality of life.
