Ciaran A. Shaughnessy, Ph.D.

Assistant Professor of Integrative Physiology, Department of Integrative Biology, Oklahoma State University

Dr. Shaughnessy's research bridges comparative, applied, and translational physiology. His lab investigates epithelial ion transport, endocrine signaling, and pharmacological modulation using bioinformatics, molecular, cellular, tissue, and whole-organism approaches. This work spans both evolutionary and biomedical contexts, including studies from the diversification of endocrine and epithelial systems across vertebrates to studies on epithelial dysfunction in diseases such as cystic fibrosis.
