Research Statement

The nucleus in cell is spatially organized within three-dimensional spaces and harbors various nuclear bodies consisting of protein/RNA/chromatin complexes, which creates microenvironments essential for fundamental nuclear functions in eukaryotes. The misregulation of nuclear bodies leads to human diseases such as neurodegenerative diseases and cancer. In plants, photobodies are photoreceptor-containing nuclear bodies that sense light and regulate almost every facet of growth and development including chloroplast biogenesis. Our lab is broadly interested in understanding fundamental functions of photobodies as developmental and environmental sensors in reprogramming growth, development, and chloroplast biogenesis in plants.
