Detailed Statement of Research Interests

Most animal species have a larval stage of development that is intermediate between the egg and the adult stages. For marine animals, the general question we address is how organisms interact with their environment. To address this complex question, we are studying genotype-environment-phenotype relationships. More specifically, we study how environmental change impacts the metabolic physiology of animal development and how genetic variation regulates growth and survival. These areas of study also include biotechnological applications directed towards enhancing "Blue Food" yield and production (marine aquaculture).
