Marco Perez, MD

Assistant Professor of Medicine (Cardiovascular Medicine)
Stanford University

Dr. Marco Perez’s research goal is to better understand the fundamental causes of cardiovascular disease through the study of genetics and epidemiology. His group studies the genetic variations and environmental exposures that are associated with conditions such as atrial fibrillation and heart failure. He has led the studies of atrial fibrillation in Women’s Health Initiative, one of the largest nation-wide population-based cohorts. He is interested in understanding the paradox that atrial fibrillation is less common in African Americans and Hispanics, despite a greater burden of risk factors such as hypertension. As director of the Stanford Inherited Arrhythmia Clinic, he evaluates families with rare inherited arrhythmias associated with sudden death such as Long QT and Brugada Syndromes and explores their links with novel genes. He also studies how best to use the electrocardiogram to identify patients at risk for atrial fibrillation and athletes at risk for life-threatening arrhythmias due to conditions such as hypertrophic cardiomyopathy. His genetic studies have led to the discovery of promising novel therapeutic targets that his group is now studying at a functional level. Dr. Perez receives funding from NIH, the Robert Wood Johnson Foundation, AHA, Stanford Cardiovascular Institute and the Stanford SPARK program.

Ellen Kuhl, PhD

Associate Professor of Mechanical Engineering and Cardiothoracic Surgery Stanford University

Dr Kuhl’s area of professional expertise is living matter physics, the creation of theoretical and computational models to predict the acute and chronic response of living structures to environmental changes during development and disease progression. Her specific interest is the multiscale modeling of growth and remodeling, the study of how living matter adapts its form and function to changes in mechanical loading, and how this adaptation can be traced back to structural alterations on the cellular or molecular levels. Growth and remodeling might be induced naturally, e.g., through elevated pressure, stress, or strain, or interventionally, e.g., through prostheses, stents, tissue grafts, or stem cell injection. Combining theories of applied mathematics, biophysics, and continuum mechanics, her lab has specialized in predicting the evolution of form and function in living structures using patient-specific custom-designed finite element models. These models can serve as diagnostic and predictive tools to explain human brain development and malformations associated with neurological disorders such as lissencephaly, polymicrogyria, schizophrenia, and autism.
