Wnt proteins are members of an evolutionarily conserved family of signaling proteins with important functions in development, adult tissue homeostasis and disease. At the cellular level, Wnt proteins can trigger a wide variety of response, ranging from cell fate specification and proliferation to cell polarization and migration. We are studying the signaling mechanisms that mediate these different effects of Wnt.

Vacancies: There are currently no vacancies for PhD students or postdocs. However, interested candidates are welcome to apply for their own funding. Please contact Rik Korswagen for details.
Undergraduate rotation projects: We usually have rotation projects for undergraduate or HLO students. Besides standard biochemical, cell biological and genetic techniques in C. elegans, projects involve live cell imaging and single molecule mRNA FISH. Please contact Rik Korswagen for details.
