Research Interests

Laurie's research focus is on livestock reproduction, animal-environment interactions, welfare and management relative to pig housing concepts. Recent and current research include: a multi-institutional project assessing sow longevity and sow lameness in different housing systems and methods of early detection of lameness; partnering with the pork industry to provide decision-making tools for producers to successfully convert to sow group housing; leading a collaborative project focused on optimizing flooring and social management of group-housed gestating sows.
