Research in the Pespeni Lab is motivated by a fundamental interest in understanding the processes that both generate and impact the incredible diversity of life that exists in the sea.

Specifically, we aim understand the mechanisms that allow populations to adapt to local conditions and that may confer resilience to future changes in conditions. We integrate population genomics, physiology, developmental biology, and ecology to meet one of the grand challenges in research today, to link genes to phenotypes to the environment. We focus on marine invertebrates because of their diversity, the threats they face, and their ease of culture in the lab. In each of our projects, we drill down to uncover the variation that underlies adaptive physiological phenotypes and we scale up to reveal the ecological and evolutionary processes that shape this variation.
