Avian thermoregulation in a changing climate

I am getting started on a new project looking at variation in downy plumage across elevational gradients in the context of anthropogenic change. Plans for this project include museum-based research utilizing specimens to assess where change has occurred in the past 100 years, as well as field work and transcriptomics to study down feather development and regulation.

The Mexican Bird Resurvey Project

​Integrative taxonomy of the Yellow Grosbeak and Black-thighed Grosbeak species complex 

Integrative taxonomy employs phenotype, genotype, and ecological niche as complementary axes of divergence to assess the extent of recent divergence in enigmatic species. I am currently working to assess species limits for members of the genus Pheucticus, ​a relatively young and species-poor genus (<3 Ma old) in the cardinal family (Cardinalidae) comprising six woodland species with large bills, which are mostly seed-eating.

Symbiosis Lab

Microbial community structure of neotropical insects specialized with Passiflora

Disonycha quinquelineatus, Pedelia, Aniscolesis flavolineata, and Edessa eburatula are
neotropical insects specialized with cyanogenic passionflower that have nutritional bacterial symbionts. My goal for this study was to learn more about these species’ internal anatomy and amplify their bacterial 16S rRNA genes to determine possible symbionts. At La Selva Biological Station in Costa Rica alongside Dr. Shana Goffredi, I collected a range of samples from different life stages, which allowed for observation of both eggs and juveniles to determine how the presence of microbes varies throughout maturity.

​Bar chart of relative microbiome composition as percent abundance (based on the 16S rRNA gene) across 4 species of insects specialized with Passionflower at different life stages. Bacterial genera comprised of a plethora of microbial OTUs were color-coded as a whole. Bacteria that occupied considerable amounts of the sample’s microbiome composition or were shared across multiple samples were labeled to indicate significance. Data was obtained from sequencing results from Laragen, Inc and compared to the GenBank database. Samples labeled VR are from one of Dr. Goffredi’s past student’s results, and were included for comparison.

Preheim Lab

In the summers of 2017 and 2019 I interned with the Preheim Lab at Johns Hopkins University's Whiting School of Engineering. ​Research in the Preheim lab focuses on the ecology of microorganisms and microbial processes impacting water quality, namely in the Chesapeake Bay watershed.
