I am a Postdoctoral Associate in the Sherwood Lab at Duke University (NC, USA) studying cell invasion in nematode worms. Before that, I completed my PhD at Uppsala University (Sweden), where I examined the role and regulation of key genes patterning the cartilage, bone, and connective tissues of zebrafish.
