My laboratory studies the genomics and biology of pluripotent stem cells as model systems of cardiovascular cell differentiation.  Our group also investigates the role of canonical Wnt signaling in the specification and fate of cardiac stem cells.  The main goal is to optimize cardiac tissue repair and translate research findings to new therapeutic strategies for human patients of heart disease.  
We have performed transcriptome analysis of mouse embryonic stem cells at the pluripotent stage and after differentiation, and organized the Functional Genomics In Embryonic Stem Cells (FunGenES) public database.  Our group took part in the NHLBI Cardiovascular Cell Therapy Research Network (CCTRN) that recently completed three Clinical Trials using stem cell therapy in human patients of heart disease. Currently, I am the Director of the Vanderbilt Hub in the NHLBI Progenitor Cell Biology Consortium (PCBC) and I also  chair the PCBC Bioinformatics Committee, whose role is to establish quality indexes and standards for human embryonic, induced pluripotent, and adult stem cells.  The Bioinformatics Committee also coordinates genomics data analysis among PCBC research groups and provides training on Bioinformatics tools to investigators.
