We study how marine organisms respond to their physical and biological environment across ecological and evolutionary time scales. We use shelled molluscs as a model system, drawing on their rich fossil record, their ubiquity in modern ecosystems, and the value of their carbonate shells as geochemical archives of past environments.

We combine field-based study of fossil occurrence with research on living organisms — underwater observations, laboratory aquarium experiments, and statistical modeling — to connect the past and present.
