RESEARCH
INTERESTS
The
huge increase in DNA sequence data has revolutionized the field of
evolutionary biology. However, we remain ignorant
about functional consequences of most genetic variation, both
within and between species. This discrepancy exists because
phenotype data cannot be gathered in a manner comparable to
high throughput sequencing technology. As a result, we
lack a fundamental understanding of how most genetic variation
affects basic fitness of an organism.
My
research aims to close this gap by linking genotype and phenotype
in an evolutionary and ecological context. I
focus on sperm competition in house mice (Mus
domesticus), which arises when a single female
mates with multiple males during a single estrous cycle. My
work takes three complementary approaches. First,
I use bioinformatic techniques to identify interesting
candidate genes. Second,
I investigate genetic variation in such genes, in both
a population genetic and phylogenetic framework. Third,
I assay sperm competitive ability in live animals, using
in vitro fertilization assays I have developed. Ultimately,
I want to link genetic variation found in steps 1 and
2 to phenotypic variation found in step 3.
