Dr. Evans’ research focuses on defining genetic pathways underlying heart development and to apply that understanding to both congenital and adult heart disease. A basic understanding of heart development is key toward understanding congenital heart disease and will inform potential cell-based therapies to repair diseased hearts. Building a functioning heart requires the specification and interaction of a number of cell lineages of distinct function. The Evans lab is trying to understand the stepwise process by which mesodermal precursors become committed to cardiac progenitors, and then specified to become distinct cardiac lineages.

The Evans lab is also studying several stem cell populations which give rise to distinct cardiovascular lineages. Model systems are mouse and embryonic stem cells. Dr. Evan’s lab has created a number of cre-expressing mouse models which will enable them to examine gene pathways required for specific cardiac lineages, including that of the proepicardial organ, cardiac fibroblasts, and the sino-atrial node. Another area of active interest is the formation of the coronary vasculature.
