Research Interests

A gene can generate multiple mRNA isoforms through alternative mRNA processing including splicing and polyadenylation. Moreover, different cell types may process mRNAs from the same gene differently to preferentially express distinct mRNA isoforms. Our lab is interested in understanding the diversity of mRNA expression in different cell types and its biological implications.

Our current research focuses on the role of abnormal mRNA processing in human disease. Our approach is to combine powerful in vivo high-throughput profiling methods and CRISPR technology with genetically modified mouse models of human disease to identify candidate mRNA isoforms that may contribute to disease pathogenesis in specific cell types in vivo. These candidate mRNA isoforms will then be further studied to reveal their biological functions and the molecular mechanisms regulating their processing. Our goal is to provide novel insights into the pathogenesis and treatment of human disease. Current areas of research include neurological disorders, hematological malignancies and liver disease.
