Immune systems organize the interactions of hosts with invading microorganisms. While symbionts are welcome guests, pathogens cause disease (and in the worst case death) and are thus the target of immune responses. The most basic mechanisms of immunity are phagocytosis (the ability to eat and digest pathogens - phagocytic cells) and cytotoxicity (the ability to kill infected cells to release the pathogens they contain so that phagocytosis can eliminate them - killer cells). We are interested in understanding how the immune systems of metazoans (=animals) evolved from these two fundamental building blocks into the complex networks of diverse immune cell types and communication/effector molecules that form their common and diversified defense mechanisms. 

  Our model systems are marine invertebrates - currently we are using Strongylocentrotus          purpuratus (purple sea urchin) and Exaiptasia pallida (a sea anemone) together with its symbiont   Symbiodinium minutum, and at times Lingula anatina (a brachiopod) – and they allowed us to   recently discover that the enzymatic machinery that is required for generating high-affinity    antibodies already existed prior to the emergence of adaptive immunity.
