Description of Research Expertise

Research Interests

Mechanisms of Cell Polarization, Cytokinesis, and Septin Assembly and Function

Key words: Cytokinesis, abscission, actomyosin ring, exocytosis, ECM remodeling, septin, hepatocyte polarization, apical tube formation

Research Description

Research in the Bi laboratory is aimed at understanding the mechanisms of cytokinesis and septin assembly and function using both yeast and mammalian cells as the experimental systems and an integrative approach involving genetics, cutting-edge imaging technologies, and biochemistry. The cytokinesis projects focus on dissecting the architecture and regulation of the actomyosin ring as well as the mechanisms of targeted vesicle fusion and ECM remodeling at the division site. The septin projects focus on elucidating the mechanisms and functional impact of septin high-order assembly and remodeling at the division site during the cell cycle.

The Bi laboratory also attempts to elucidate the mechanisms of hepatocyte polarization and apical tube formation using cell culture models and an integrated experimental approach.


Rotation projects: interested students are welcome to discuss possible rotation projects.
