This Engineering Research Initiation (ERI) project supports research that studies the fundamental biomechanics of stomach motility to better understand how its complex structure contributes to digestive function. Millions of Americans suffer from gastrointestinal disorders such as irritable bowel syndrome and gastroparesis, which cause significant discomfort and healthcare costs. These conditions are difficult to diagnose and treat because the stomach is not a uniform organ—it has multiple layers, each with different mechanical properties and fiber orientations that influence its ability to contract and move food. This project aims to fill this knowledge gap by integrating medical imaging, computer modeling, and biomechanics to study the stomach’s mechanical behavior in detail. By establishing a scientific foundation for stomach function, this research looks to help advance biomechanics and mechanobiology while training students in cutting-edge computational and experimental techniques. The project will also support science, technology, engineering, and mathematics education by offering hands-on training in biomedical engineering, computational modeling, and soft tissue mechanics, contributing to the development of a skilled workforce in biomedical research and healthcare technology. This study intends to develop a multiscale, physics-based electromechanical modeling framework for stomach motility by integrating microstructure-based mechanics, ion-based electrophysiology,
