About

Ryan C. Gessner is a biomedical engineer whose research centers on advancing preclinical ultrasound imaging to bridge the gap between clinical diagnostics and laboratory animal models. His major contributions lie in developing robotic, high-throughput ultrasound platforms that enable noninvasive, longitudinal 3D imaging of rodents—a critical tool for studying disease progression without sacrificing animals. Gessner’s work on a widefield 3D ultrasound system (18 citations) provides researchers with a cost-effective, radiation-free alternative to MRI and CT for visualizing anatomy and function in vivo. He further pioneered a robotic shear wave elastography system (16 citations) for noninvasive staging of liver fibrosis in murine models, directly translating clinical elastography to preclinical drug development. His validation studies combining ultrasound with bioluminescence imaging against MRI in orthotopic pancreatic tumors (12 citations) demonstrate the platform’s accuracy for deep-tissue cancer research. Gessner has also applied his robotic ultrasound to assess polycystic kidney disease and renal morphology, offering quantitative biomarkers like total kidney volume. By making high-resolution, automated imaging accessible, Gessner’s innovations empower preclinical researchers to monitor disease dynamics with unprecedented precision, accelerating the path from bench to bedside.
