Area of Interest

My lab investigates the molecular and cellular mechanisms underlying tissue morphogenesis. The formation of three-dimensional tubular structures from flat epithelial sheets is a key process of organ formation in all animals, including mammalian lungs, kidney and digestive organs. Yet, we do not fully understand how such dramatic changes in tissue structures occur on a cellular level, and what molecular components regulate this fundamental process. My approach takes advantage of powerful Drosophila genetics, live imaging and computational analysis. Specifically, using Drosophila embryonic tubular epithelia as models, I seek to understand how the forces driving spatiotemporal changes in cell shape, arrangement and position are generated and transmitted during epithelial tube formation. These studies provide a basis for understanding general processes of organogenesis. 

Positions Available- We are recruiting 1-2 PhD students (to begin Fall 2018; application deadline Jan 10) and a postdoctoral fellow (position immediately available). If interested, please email Dr. SeYeon Chung (seyeonchung@lsu.edu).
