Joey Bernhardt

Ph.D., Zoology

2018-2020 Post-doctoral fellow, McGill University

Post-Doctoral Fellow, Biology (McGill University)

Joey’s research seeks to understand how populations and communities adapt and persist in changing environments. She integrates across levels of biological organization to quantify how flows of energy and materials at the level of the individual cascade up to shape populations over environmental gradients. By combing theory, experiments and synthesis, she aims to understand the metabolic underpinnings of biodiversity and the connections between biodiversity and human well-being. Her work unifies perspectives on energy flow with population and community ecology to advance a more coherent and mechanistic science of global change.
