Projects focus on the evolutionary ecology of sponges (and other invertebrates) in temperate and tropical marine systems. Using molecular and field-based techniques, we study factors that influence population characteristics and community structure and function (e.g., symbiosis, predator-prey dynamics, morphological plasticity and anti-predator defenses).
