I am a 3rd-year PhD cadidate in the Lively lab. I study the evolutionary pressures that drive populations to diverge in their reproductive strategies. . Specifically, I examine the role of host-parasite coevolution in the evolution of sexual reproduction and the maintenance of genetic diversity. I use four different approaches: phylogenetic comparative analyses of mating system and parasitism in the phylum Nematoda, experimental evolution in the laboratory using nematodes and their parasites, theoretical simulation, and field-based experimentation in natural populations of freshwater snails and their parasites in New Zealand.
