Casey O'Hara is a project scientist studying the impacts of human activity and climate change on marine biodiversity. His work examines the intersection of anthropogenic stressors with the ranges of species affected by those stressors to understand spatial patterns of human impact, to help inform effective marine conservation. As a data scientist, Casey strives to incorporate best practices of reproducibility and open science in his research. He also enjoys working with students to help them develop their own data science skills, formally as a lecturer and informally through workshops and lecturing.
