William Goodyer is an MD/PhD who graduated from McGill University in Montreal, Canada with a BS with Honors in Biology prior to completing his medical and graduate studies at Stanford University in the Medical Scientist Training Program. His undergraduate research focused on the molecular regulators involved in C. elegans meiosis in the lab of Dr. Monique Zetka, while his PhD (Dr. Seung Kim lab) centered on the molecular mechanisms governing pancreatic beta-cell maturation and proliferation in vertebrates. He next pursued accelerated research tracks for both Pediatric Residency (Boston Children’s Hospital, 2013-2015) and Pediatric Cardiology Fellowship (Lucile Packard Children’s Hospital, 2015-2017), where he developed a passion for Electrophysiology. As such, he next performed a postdoctoral fellowship in the Dr. Sean Wu lab at the Stanford Cardiovascular Institute (2017-2019), focusing on the discovery of novel regulators underlying the development of the cardiac conduction system (CCS). To overcome the inherent hurdles of studying the CCS (small cell numbers, cell type heterogeneity, etc), he developed a comprehensive transcriptional profile of the entire CCS at single-cell resolution, providing a gene atlas for facilitating future efforts in conduction cell identification, isolation, and characterization in the context of development and disease. He has recently completed his Pediatric Electrophysiology Fellowship (2019-2020) and has stayed on at LPCH as an Instructor, pursuing both clinical Pediatric Electrophysiology and basic science research focused on CCS development and disease in order to stimulate future translational opportunities aimed at the prevention and treatment of heart rhythm disorders.
