Isabella Smith is a junior in Biomedical Engineering at Texas A&M who joined OBSL in January 2026. Her research focuses on a phantom finger model that gives small wearable sensing devices a controlled, reproducible benchtop test environment, from designing and fabricating molds and phantom structures in SolidWorks to 3D printing and other prototyping methods. She has since expanded into pediatric cardiac research, helping design a phantom heart test bed to evaluate an in-utero catheter device being developed for fetal cardiac intervention, and continues to build hands-on experience in electronics assembly, soldering and wearable device testing across the lab’s projects. Isabella is passionate about improving healthcare access in underserved communities through cost-effective medical technologies, and she takes part in medical mission trips that repair and maintain critical medical equipment.
