The people behind the papers – Joey Ghersi and Stefania Nicoli

Akt is believed to be important for vascular development, but complex tissue-specific loss-of-function studies have been difficult in mice because of embryonic lethality. In a new study, Wenping Zhou, Joey Ghersi, Stefania Nicoli and colleagues report the phenotype of a complete Akt mutant zebrafish and its role in arterial specification via Notch signaling. To learn more about their work, we spoke with corresponding authors Joey Ghersi, Assistant Professor at Centre Hospitalier Universitaire (CHU) Sainte-Justine, Canada, and Stefania Nicoli, Associate Professor Tenure at Yale University, USA.
