Summary of Long-Term Research Interests

My research interests combine the fields of evolutionary ecology and molecular microbiology. I am particularly interested in how antagonistic (parasitic) and beneficial (mutualistic) microbial symbionts shape host ecology and evolution, how partners complement each other metabolically, and how host-symbiont associations defend themselves against exploitation. My work is fundamental in nature, but encompasses components of applied significance, such as the natural use of antibiotics, antibiotic resistance in parasites, and plant decomposition enzymes of interest to biofuel production. My focus is on the almost completely unexplored presence and role of additional symbionts associated with fungus-growing termites, part of the integrated approaches of my long-term research focus areas:

i) The evolution of symbiont complementarity. My studies of the contributions to plant decomposition by termites and their fungus gardens have provided the first -omics evidence of an intricate connection between the natural history of substrate processing and symbiotic partner complementarity.

ii) The evolution of termite microbiotas. We have established that the shift in fungus-growing termite gut microbiota composition coincided with fungus domestication 30MYA, and that a core set of microbes persists in the guts of the fungus-growing termite sub-family. This compositional shift was associated with the reduced handling of complex carbohydrates (now taken care of by Termitomyces fungi) and an enrichment of enzymes for fungal cell wall breakdown in the microbiota. Despite ancestral shared functional roles, gut communities have diversified: congeneric termite species have more similar microbiotas than species from different genera.

iii) Disease-defence dynamics in fungus-growing termites. With only Pseudoxylaria weeds being present in dying or abandoned combs, and culture-independent approaches indicating the virtual absence of other fungi within fungus combs, gut-mediated selective inhibition of non-mutualists in the substrate for Termitomyces growth is a candidate hypothesis.
