Professor Dong’s research interests include lysosome physiology and lysosome-related diseases. His primary interests are lysosomal ion channels and transporters. Investigation of these lysosomal channels and transporters will facilitate our understanding of the pathogenic mechanisms of many lysosomal storage diseases as well as neurodegenerative diseases.
