The Department of Developmental Genetics investigates questions related to organogenesis including cell differentiation, tissue morphogenesis, organ homeostasis and function, as well as organ regeneration. We study these questions in zebrafish as well as in mouse and are currently looking at several mesodermal (heart, vasculature) and endodermal (pancreas, lung) organs. We utilize both forward and reverse genetic approaches, and aim to dissect cellular processes using high-resolution live imaging. One goal of our studies is to gain understanding of vertebrate organ development at the single-cell level, and beyond.
1) Cardiac development and regeneration
Projects aim to understand key aspects of cardiac development including trabeculation and valve formation at single cell resolution. Other projects delve into relatively unexplored areas of cardiac regeneration including the role of the immune system as well as cardiac valve regeneration.

2) Vascular development
Projects aim to understand endothelial cell differentiation and behavior in the context of blood vessel formation in zebrafish and mouse.

3) Genetic compensation and transcriptional adaptation
The goal of this project is to define the molecular mechanisms underlying the broadly reported but poorly understood phenomena of genetic compensation and transcriptional adaptation.
