I am an evolutionary ecologist interested in using a multidisciplinary approach to investigate how environmental variation and evolutionary processes converge to influence the patterns of demographic, genetic, and genomic variation in natural populations, especially those of conservation concern. Projects that I am currently engaged in include:
- effects of forest fires on the demography and genetic signatures of collared lizards
- repeated patterns of evolution in founding populations of collared lizards
- influence of metapopulation dynamics on estimates of variance effective size of populations
- patterns in organisms' abilities to acclimate to environmental variance
