Significant progress has been made over the past two decades on the pathogenesis of individual neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), as well as their distinct neurodegenerative processes. However, different neurodegenerative syndromes have been mainly studied mechanistically in isolation. There has been a lack of concerted effort to ascertain whether and how these pathogenic processes may be linked to one another. The Chen laboratory is interested in understanding the pathogenesis of neurodegenerative disorders, developing diagnostic markers and validating therapeutic targets. The laboratory uses an interdisciplinary approach involving Drosophila model, rodent model, iPS cells and postmortem human brain tissue to study the mechanisms underlying neurodegeneration in central nervous system.
