Research Interests

We study the regulation of cell-cell adhesion during morphogenesis and cell migration. We use microscopy in cell cultures and in the model organism C. elegans to address basic questions about how cells connect to and sense their environment, be it a neighboring cell or the surrounding matrix. We are particularly interested in the role forces play in the regulation of cell adhesion and in the interplay between cell adhesion and the actin and microtubule cytoskeletons.
