Laboratory of Neurodegeneration and Translational Biology

Our laboratory, through the integration of multidisciplinary approaches employing protein engineering, biochemical, biophysical, and cell biology methods, is interested in studying the molecular mechanisms underlying the development of neurodegenerative diseases such as motor neuron diseases and Parkinson’s disease. Proteins, the most abundant macromolecules in cells, play diverse roles in cellular functions when in their native conformations. In neurodegenerative diseases, a few but specific proteins, upon losing their native conformations, form aberrant assemblies within cells of the nervous system and are believed to contribute to the pathogenesis of the respective diseases. Interestingly, many of these neurodegenerative diseases share commonalities and heterogeneities in their disease-causing mechanisms, ranging from the nature of the proteins and their cellular characteristics to the clinical symptoms observed in patients. The molecular basis of this phenomenon, the major contributors to these diseases, and their underlying pathological mechanisms are the primary focus of our laboratory’s interest. Along with our efforts in studying disease mechanisms, our lab aims to translate laboratory findings into methodologies and tools to assist the academic and industrial communities. Ultimately, through our learnings at the molecular level, we are keen to develop close-to-human disease models using cellular systems to discover effective therapeutic options for these devastating diseases.
