Evolution of Host-Parasite Interactions
My research integrates the disciplines of immunology, parasitology, ecology, evolution and genetics to study the underlying principles of host/parasite co-evolution.
I am interested in the evolution and diversification of immune systems in invertebrate model systems. Pathogens and especially specialized parasites impose considerable selective pressures on their hosts. Therefore it is not surprising that animals of different phyla have independently acquired capabilities for diversifying parasite recognition and immune responses. In fact, diversification of genes or gene families of immune factors is now considered a common feature of animal immunity across phylogeny. Highly variable molecules assuming potential immune function may be found in any phylum of invertebrates. Among those, I am interested in the immune role and diversification of 185/333 proteins in sea urchins and Fibrinogen-related proteins (FREPs) in molluscs.
Another important research activity focuses on the role of host and parasite symbionts in resistance or virulence. UnderstandingParasite strategies for evasion, manipulation or exploitation of hosts and Host strategies for resistance or tolerance to parasitism is of interest in many fields, from ecology to medical sciences. Generally, studies have focused on either the host response to parasitosis or the parasite virulence mechanisms. However, host and parasite co-evolve with a myriad of associated microorganisms that could benefit from an improved fitness of their host. The hologenome theory of evolution considers that the holobiont (defined as the host and all its associated microorganisms) is the unit under natural selection in evolution rather than the host itself. I am applying a rigorous integrated analysis of host-parasite interaction, including these associated microorganisms, to obtain a holistic understanding of disease evolution.
Finally, I am interested in the effects of anthropogenic stress conditions on the different partners of the interaction. For example, I have recently been involved in a project monitoring the impact of heat stress and acid stress on coral susceptibility to Vibriosis.
Choice of organisms is based on biological diversity, evolutionary heterogeneity, presence/knowledge of symbionts, economic importance and opportunities to work in the field and interact with the organisms in their natural ecosystems.
Because of the multidisciplinary nature of my research, students with a variety of backgrounds and skills are welcomed, and undergraduate and graduate student research can be incorporated into all aspects of my work. Depending on the student’s interests and time constraints, they can be involved in lab work, parasite characterization, animal husbandry, genomics, transcriptomics, proteomics, and bioinformatics .
