  TBI is the leading cause of death and disability worldwide, especially in children and young adults. TBI survivors usually suffer from varying types of disabilities, such as body motor dysfunction, language and communication difficulties, and psychological and social cognitive defects. TBI can lead to delayed-onset neurodegenerative syndromes such as chronic traumatic encephalopathy (CTE). Unfortunately, we know so little about the mechanisms underlying the pathology of CTE, and there are no effective medications currently available for prevention and treatment of CTE.

  Currently, we are characterizing the effects of TBI on endogenous neurogenesis and identifying both genetic and epigenetic factors which might be associated with a complex cascade of molecular, cellular and immune responses, resulting in abnormal neurogenesis, neuroinflammation, neuronal injury, and cell death. Our research interests include, but are not limited to: 1) characterizing the effects of TBI on endogenous neurogenesis; 2) elucidating mechanisms underlying the pathology of TBI; and 3) examining the therapeutic potential of transplanted stem cells in brain injuries. The long-term goal of our research is to develop new approaches, including stem-cell-based therapies, for treatment of brain injuries.

Plain english:
  Traumatic brain injury (TBI) is the damage to the brain due to sudden trauma, either by penetrating or, more commonly, by closed head injury. TBI is a major public health and socioeconomic problem around the world. Approximately 1% of the population of developed countries experiences TBI each year (CDC 2012). TBI survivors usually develop many troubling symptoms, such as seizures, pain, body motor dysfunction, memory loss, and psychological and social cognitive defects. Recently, some evidences indicate that TBI may interact with other factors to trigger neurodegenerative diseases, such as Parkinson’s disease and Alzheimer’s disease. Stem cells have been considered as new therapies in the hopes of stunting neurological disease and injury, and there are growing evidences showing that experimental TBI induces abnormal neurogenesis in the adult brain. We would like to use our recently-developed mouse models of TBI to continue to identify genetic and epigenetic factors that result in altered endogenous neurogenesis and neurodegeneration following TBI, and finally to try to develop stem-cell-based therapies for brain injuries.
