    Burns C. Blaxall, PhD, FAHA, FACC, FAPS 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.

    Jonathan W. Byrnes, MD Attending Cardiac Intensivist, Cardiac Intensive Care Unit

    is a cardiac intensivist who is active in clinical and translational research involving extracorporeal life support. This research is focused on the biocompatibility of the patient/device interface and the associated interaction of coagulation and inflammatory pathways. The aim of these endeavors is to decrease the incidence of end organ dysfunction and stroke associated with these therapies.

    Allison A. Divanovic, MD Co-Director, Medical Student/Resident Education, Heart Institute

    is interested in improving the pre- and postnatal outcomes of infants with congenital heart disease. Her research has evaluated factors that increase risk of intrauterine fetal demise in fetuses with congenital heart disease. She has also conducted research to improve prenatal diagnosis of coarctation and HLHS with restrictive atrial septum. Analyzing cost effectiveness of murmur evaluations in kids is also an ongoing interest.

    Stuart L. Goldstein, MD, FAAP, FNKF Director, Center for Acute Care Nephrology

    focuses on all aspects of acute kidney injury (AKI) spanning from translational work in AKI biomarker validation to long-term AKI epidemiology and outcomes. He is specifically interested in improving outcomes in the critically ill child with or at risk for AKI.

    John Lynn Jefferies, MD, MPH, FAAP, FACC Co-Director, Advanced Heart Failure and Cardiomyopathy

    is a clinical cardiologist who has translational and clinical research programs. His research involves cardiomyopathy and cardiovascular genetics with specific interest in dystrophinopathies and aortopathies in children and adults. He also has clinical research projects investigating novel biomarkers of heart failure, chemotherapy induced cardiotoxicity, and the cardiorenal syndrome.

    Timothy K. Knilans, MD Director, Clinical Cardiac Electrophysiology and Pacing

    is a clinical cardiac electrophysiologist with a large clinical practice in management of arrhythmia and syncope. He has extensive experience in non-invasive electrocardiographic methods and invasive therapeutic modalities including catheter and surgical ablation and implanted electrical device therapy. His research interests center on evaluation and treatment of syncope and prevention of sudden cardiac death.
