Burns C. Blaxall, PhD, FAHA Director of Translational Science, Heart Institute
is interested in understanding the molecular mechanisms associated with the development and progression of heart failure. We are particularly interested in developing novel heart failure therapeutics targeting myocardial function and fibrosis. To this end, we also seek to understand the pathologic role of cardiac myocyte and non-myocyte (i.e.. fibroblast) intercellular communication.

Katherine Yutzey, PhD
is focused on the molecular mechanisms of heart development and disease. Particular emphasis is on signaling pathways and transcription factors that control heart valve development as well as contribute to pediatric and adult valve disease. Additional projects address the development of coronary vasculature, cardiac fibrosis and maturation of cardiac muscle after birth.

Katherine E. Yutzey, PhD, is a professor who joined the Division of Molecular Cardiovascular Biology at Cincinnati Children's Hospital Medical Center in 1995.
Dr. Yutzey is the first recipient of the Fifth Third Bank/Charlotte R. Schmidlapp Women Scholars Award and was also a recipient of a Children's Hospital Medical Center Trustee Award. Her work is also supported by grants from National Institutes of Health (NIH) and the American Heart Association.
The focus of Dr. Yutzey's research program is the regulation of normal and abnormal heart development. Congenital heart defects represent one of the most common classes of human birth defects. Increasing evidence exists for a genetic basis of certain instances of congenital heart disease.
Dr. Yutzey’s lab also studies molecular mechanisms of cardiac connective tissue cell lineage development and disease. This work focuses on heart valve development and disease as well as mechanisms of cardiac fibrosis.
