In March 2025, Ryan Van Hooser developed an ontology extension for stomatogastric ganglion neurons in the obophenotype/cell-ontology repository, focusing on new neuron types derived from crabs and lobsters. He applied his expertise in bioinformatics, data modeling, and ontology development using OWL to define cell types and add detailed annotations. His work included updating import statements and refining taxonomic classifications, which improved the consistency of cross-species data integration. The changes enabled more robust annotation and integration of crustacean gastric mill and pyloric neuron datasets, demonstrating a deep understanding of both biological complexity and the technical requirements of ontology engineering.
