Research topic: 

Mechanism of gene regulation at RNA and protein levels.

My research program focuses on how gene regulation impacts diseases states including cancer, neurodegeneration and virus infection. Recent research focus includes noncoding RNAs, such as circular RNAs and microRNAs, and a druggable protein modification called poly(ADP-ribose). Poly(ADP-ribose) polymerase (PARP) inhibitors are currently approved by FDA to treat multiple cancers. Though therapeutically important, this modification is understudied partly due to a woeful lack of tools. My team invents tools to investigate this protein modification, discovering its roles in various RNA processes, RNA virus infection, and the formation of membrane-less organelles. To dissect the underlying mechanisms, our team also use a range of multi-disciplinary techniques from chemical probe synthesis, single-molecule biophysical measurements and quantitative imaging to informatics, genomics and proteomics approaches. Our team is highly collaborative drawing expertise within the lab, the university and around the world. Our goal is to translate our multi-dimensional scientific findings to therapy and diagnostics.
