Research Interests My major research focus is the pathogenesis of heart failure.
Of particular interest are the mechanisms responsible for adverse cardiac extracellular matrix (ECM) remodeling associated with the progression of congestive heart failure.
Current topics of study include:
the role of lysyl oxidase, a collagen crosslinking enzyme, and related peptides in myocardial ECM remodeling,
the cardioprotective effects of estrogenic pathways, including soybean- and plant-derived compounds, and
the cardiac effects of inhaled particulate matter and cigarette smoke.
My laboratory utilizes rodent models of cardiac disease, including models of pressure and volume overload.
We also use primary adult cell culture to examine specific pathways involved in the remodeling process.
