Incoming Cardiovascular Medicine Fellows


Dr. Bell was born and raised in Denver, Colorado and attended college at the University of Colorado - Boulder where she had the opportunity to work with Dr. Tom Cech investigating telomerase biochemistry.  She completed her MD at Vanderbilt University Medical School, during which she spent a year as a Howard Hughes Medical Investigator research fellow researching melanomagenesis through the lens of genetics and stem cell biology.  She then trained in internal medicine at Stanford University Hospital before continuing her clinical training in cardiology.  She plans to pursue a career as a physician-scientist, leveraging her prior research experiences to investigate the process of atherogenesis and determinants of smooth muscle cell fates leading to clinically significant vascular disease.



Dr Elezaby attended college at the University of Arizona, where he studied molecular and cellular biology. He graduated from the MD-PhD program at Boston University, with a dissertation focus on the effects of diet on mitochondrial function and oxidative stress in the heart. He completed residency training in internal medicine at Stanford as part of the Translational Investigator Program, and intends to pursue a career studying cardiac metabolism with a clinical focus on heart failure.



Dr. Ning was born in China, but she grew up mostly in Texas. She went to the University of Texas at Austin for undergrad and received her PharmD degree at the College of Pharmacy. She received her MD degree from UT Southwestern Medical Center and moved to California for Internal Medicine residency at Stanford. Dr. Ning plans to continue her training as a cardiology fellow at Stanford. She is passionate about both cardiology and oncology and thoroughly enjoys taking care of these patient populations. Subsequently, she has completed several research projects and publications in both fields. She hopes to combine her clinical and research interests by contributing to the growth of the field of cardio-oncology. She hopes she can also use her pharmacology background to better understand the complex pharmacokinetics and pharmacodynamics involving oncology therapies and cardiotoxicity. She is particularly interested in the role of noninvasive imaging to help identify these patients that may be at risk for cardiotoxicity. 



Dr. Weldy received his MD from Duke University and came to Stanford as an internal medicine resident and member of the Stanford Translational Investigator Program (TIP). Prior to medical school, Dr. Weldy completed his PhD in Toxicology at the University of Washington (UW) where his research focused on genetic determinants of antioxidant biosynthesis, redox biology, and vascular function in response to inhaled toxicants. Dr. Weldy then completed a postdoctoral fellowship at the UW Division of Cardiology where he studied the relationship between cardiac development and adult heart failure. His work led to the discovery that in utero exposure to air pollution increases adult susceptibility to heart failure in mice. As a resident at Stanford, he has conducted research investigating how global profiles of circulating miRNA can predict RV failure in adult patients with tetralogy of Fallot. Dr. Weldy plans a career as an academic clinical cardiologist and basic scientist with the goal of elucidating novel mechanisms of disease by characterizing the relationship between the developing heart and adult cardiovascular disease.           



Dr. Sanchez grew up in Barquisimeto, Venezuela. He attended college and medical school at the University of Arizona in Tucson. He did Internal Medicine training at Brigham & Women’s Hospital, research under the tutelage of the Thrombolysis in Myocardial Infarction (TIMI) group, and was Chief Resident from 2018-2019. He is broadly interested in Cardiology Critical Care and mechanical circulatory support. His research centers on clinical outcomes of the complex patient composition in the modern Cardiovascular Intensive Care Unit. He is now a fellow at Stanford and plans to pursue a career in Critical Care and Cardiovascular academic medicine. 



Dr. James Tooley was born and raised in Tucson, Arizona. He attended Johns Hopkins University where he graduated with honors with a degree in Biophyiscs. He received his MD and MHS from Yale School of Medicine, where he graduated cum laude and was a Howard Hughes Medical Institute research fellow. He completed his Internal Medicine residency training at Stanford. He is interested electrophysiology, ECGs, and research using the electronic healthcare record. James plans to have an academic career as a clinical investigator practicing electrophysiology.
