Research Fellow

Research Interests

During my PhD in Antonio Jacinto’s lab, Portugal, I studied how signaling mediated by Rho1 GTPase is temporally and spatially controlled during morphogenesis via RhoGEFs and RhoGAPs, using epithelial cell invagination in the Drosophila embryo as a model system. In Jennifer Zallen’s lab, at SKI, I have studied how a downstream target of Rho1 - Rho kinase - controls planar polarization of epithelial cells during convergence and extension movements in the Drosophila gastrula.
