Description of Research Expertise:
My research interests are in translational cardiovascular epidemiology with a focus on the study of novel signaling pathways and mechanisms in human heart failure, cardiac remodeling, and cancer therapy cardiotoxicity. Current areas of research include:
1) Neuregulin Signaling:
We are interested in defining the relevance of circulating neuregulin as it relates to human heart failure and cardiac remodeling. I am the principal investigator of a longitudinal study determining the association between circulating neuregulin levels and cardiac remodeling and clinical outcomes in the Penn Heart Failure Study and the Chronic Renal Insufficiency Cohort.
2) Mechanistic Biomarker Studies in Cancer Therapy Cardiotoxicity:
We are interested in defining novel circulating biomarkers and genetic variations predictive of cancer therapy cardiotoxicity. Our objective is to gain mechanistic and translational insight into the pathophysiology of this disease. We have ongoing studies in specific pathways and biomarkers of interest, as well as proteomics discovery across various cardiotoxic regimens.
3) Myocardial Mechanics in Cancer Therapy Cardiotoxicity and Heart Failure:
We are interested in gaining insight into alterations in myocardial mechanics and sensitive measures of cardiac function, as defined by echocardiography, in patients exposed to cardiotoxic chemotherapy regimens as well as patients with chronic heart failure.
