Bill Hucker earned his MD and PhD degrees from Washington University in St. Louis in 2009. His PhD work focused on the electrophysiology of the atrioventricular (AV) junction, and developing imaging methods to study structural and functional heterogeneity in both the rabbit and human tissue. He then came to MGH for internal medicine residency, chief residency, and cardiology fellowship. He joined the Ellinor lab in 2015. Since that time, his work has focused on using stem cell derived cardiomyocytes to investigate the function significance of genes that are associated with atrial fibrillation by genome wide association studies.
