Research Description:
Research in my laboratory explores patterns and mechanisms of rapid evolution during invasions into novel habitats. Much of my work examines adaptive evolution within the context of multiple independent invasions to determine whether the same evolutionary pathways are involved during independent invasions. Exploring the degree of parallelism across independent invasions could reveal the degree to which mechanisms of adaptation are labile or constrained.

Using this comparative framework within a phylogenetic context, research in my laboratory is now exploring: (1) physiological evolution during habitat invasions, (2) specific loci that are under selection during habitat shifts, and (3) microbial diversity associated with the invading host, as well as evolution of host-microbiome interactions during invasions.

In addition, my laboratory is now performing comparative genomic analyses to study patterns of genome and physiological evolution across Arthropod lineages. Now, for the first time, we can study lineages outside of insects, such as several crustaceans (copepod, amphipod), chelicerates (spiders, mites, and scorpions), and myriapods (centipede, millipede).

We are now embarking on a study across the phylum Arthropoda to explore physiological adaptations associated with major habitat transitions, i.e., colonizations from marine ancestral habitats into freshwater habitats and onto land. These habitat transitions are important for understanding Arthropod physiology, as these colonizations have led to key innovations and fundamentally shaped the architectural diversity across the Arthropoda. For example, many traits in insects arose as a consequence of invasions by their crustacean ancestors from marine into freshwater and terrestrial habitats, leading to the radiation of insects.
