Biography

Devon Guerrelli is a PhD student in the Biomedical Engineering department at The George Washington University. Devon's research focuses on pediatric cardiac electrophysiology, specifically how common cardiac intensive care unit therapies (plastic medical devices, off-label medications, blood transfusions, etc.) alter cardiac conduction. In addition, Devon employs microelectrode arrays, isoelectric focusing, electron microscopy and fluorescent imaging to investigate age dependent changes in cardiac conduction and structure. Devon is involved in multiple collaborations with various research groups including Dr. Ishibashi’s lab at Children’s National Hospital to better understand how chronic perinatal hypoxia delays cardiac maturation in cyanotic congenital heart disease and Dr. Weinberg’s lab at The Ohio State University to develop pediatric cardiac electrophysiology computational models. Devon also works closely with the Cardiac Surgery team at Children’s National to coordinate multiple clinical research studies.

Biography

Luke Swift, PhD, is developing an animal model of cardiovascular development for the purpose of improving drug application in a pediatric population – and he brings a broad range of previous research experience. His previous projects have included identifying the mechanism underlying anthracycline cardiotoxicity, discerning the cellular factors behind the initiation of ectopic cardiac activity, and applying hyperspectral imaging to improving the next generation of ablation catheters. Outside of the lab, he continues his work on his own cardio as an avid cyclist.
