An award is made to Reed College to enable the development of computational tools that model complex tissue structures in the vertebrate eye. By combining advances in live imaging microscopy and computational image analysis, the project will generate graph-based models that capture patterns of cell organization in the developing zebrafish retina. The project will also create reproducible protocols for applying these tools to publicly-available imaging datasets, expanding access to scientists with limited imaging and compute resources. Broader impacts include new undergraduate educational opportunities in computational image analysis and a faculty mentoring network at predominantly undergraduate institutions (PUIs) to build capacity for undergraduate teaching and research at resource-limited institutions. The three-year peer mentoring network will foster professional development and resource sharing among PUI faculty, strengthening the nation’s STEM workforce through expanded access to undergraduate computational biology training. The project advances fundamental methods for analyzing complex tissues by integrating graph theory with high-resolution microscopy. While graphs have long been used in systems biology, their full potential has not been leveraged for modeling multi-cell patterns in tissue imaging. Further, neuronal tissues such as the eye complicate traditional modeling approaches due to elongated cell shapes. To address a need for models that reflect the spatial c
