Faculty Spotlight: Amanda Gibson

How do natural populations adapt to rapidly changing environments? What forces underlie the maintenance of diverse reproductive and life history strategies? The Gibson lab pursues these questions through the study of hosts and parasites, because antagonistic interactions can impose strong but highly variable selection.  We’re broadly interested in coevolution, or reciprocal changes in genotype frequencies of host and parasite populations, and in the relevant ecological variation that may strengthen or destabilize those cycles.  We currently work mostly with nematodes, because 1) they keep posing interesting questions, about genetic diversity, disease spread, life history, reproductive mode, and more! and 2) they excel at making babies fast, so we can do creative, highly replicated experiments, including experimental evolution and field-based manipulations.  Check out our lab website for more information: coevolving.org
