RESEARCH
INTERESTS
I am interested in understanding how different
evolutionary forces have shaped patterns of nucleotide variability
within natural populations and across the genome. Currently,
I am exploring the role of antagonstic coevolution between wild
house mice and their pathogens, from the perspective of the mouse
host. Genes involved in immune responses have elevated rates
of protein evolution across many diverse taxa, which suggests that
such genes are the targets of adaptive evolution. However,
it remains unclear what evolutionary forces affect immunity genes
within populations. My dissertation is describing on the
evolution of genes involved in innate immunity in house mice and
comparing these to non-immunity control genes. I am using
a candidate gene approach coupled with a phenotypic screen to explore
the relationship between particular pathogens and mouse defenses.
