Current research
Our research is highly diverse and includes topics ranging from embryogenesis, cell reprogramming and organogenesis to aging and stem cell engineering.
Our ongoing and future work will focus on new and emerging areas of developmental biology, such as epigenetics and genomics.

Model systems
We house one of the largest zebrafish facilities in the world. Along with zebrafish (D. rerio), we study several other model systems, including the fruit fly (D. melanogaster), nematode (C. elegans) and mouse (M. musculus), as well as tissue culture systems and embryonic stem cells.
