My research to date has involved field work in Antarctica, Africa and New Zealand to sample for invertebrates in both terrestrial and aquatic realms. By utilizing genetic methods, such as DNA barcoding, we are able to assess the distribution of genetic variants (phylogeography) to answer ecological questions. For example, assessing levels of genetic variation between geographically-separated populations gives insight to potential dispersal pathways or the timing of past isolation events.

I would be interested in expanding on these skills through future research projects such as the metabarcoding of bulk arthropod samples for measuring community-level changes over space and time, or metabarcoding the gut contents of invertebrates to inform predator-prey relationships.
