Before joining the Stonehill College community in 2022, Erica Holdridge completed a postdoctoral fellowship at Boise State University through the National Science Foundation. Her research interests include studying bacteriophage and their hosts in carnivorous pitcher plants, as well as other wetland ecosystems; using and developing bioinformatics tools to study community ecology in microbial systems; and examining complex systems models in community ecology. Her scholarly work has appeared in publications like Theoretical Ecology, Ecology and Evolution, and Ecosphere.
