Smith Center for Outcomes Research.  She is a member of the faculty of Harvard Medical School with official appointment in process.  Dr. Upshaw studies the intersection of cardiovascular disease and cancer with the goal of optimizing both cardiovascular and cancer outcomes in this growing population of patients.  She utilizes observational and clinical trial designs to study the cardiovascular effects of cancer and cancer therapies, test novel treatment strategies, and understand the comparative effectiveness of interventions in populations not well represented in clinical trials.  She is co-chair of the National Cancer Institute funded ECOG-ACRIN Cancer Research Group Cardiotoxicity Subcommittee.  Her clinical expertise is in cardio-oncology and advanced heart failure and transplant cardiology.

Richard L. Verrier, PhD, FACC

Richard L. Verrier, PhD, FACC, is an Associate Professor of Medicine at Harvard Medical School and Director of Integrative Cardiac Electrophysiology Laboratory at BIDMC. His research focuses on neural control of heart rhythm with particular reference to atrial fibrillation and sudden cardiac death. He and his colleagues investigated cardioversion by pulmonary delivery of antiarrhythmic agents. They developed analytical means to detect ventricular repolarization abnormalities capable of noninvasively identifying the presence of clinically significant coronary artery stenosis and risk for malignant arrhythmia during routine exercise tolerance and pharmacologic stress testing. In collaboration with faculty members in Neurology, he has characterized a new entity, the "Epileptic Heart," which provides a framework for improved understanding of the factors responsible for premature cardiac death in patients with chronic epilepsy.
