I have sequenced, assembled and annotated the de novo sea otter genome, and compared it to the giant otter genome to discover genetic changes associated with aquatic adaptation and the impact of the extreme fur trade bottleneck on genetic diversity. I am now using a custom sequence capture to study demographic history and genetic load in modern sea otter populations using modern and ancient DNA. I have also compared methods of demographic inference from genomic data to determine which methods, if any, are able to recapitulate multiple summaries of the data, and written a review of popular demographic inference methods and their applications to non-model organisms. In the past I have worked on forward-in-time simulations to assess the impacts of the 18th-19th fur trade on sea otter genomic diversity and genetic load, characterized the cetacean gut microbiome with high-throughput sequencing data, and modeled human demography using the site frequency spectrum.

Thesis Description: I collected cetacean fecal samples for genetic and chemical analysis, extracted genomic DNA from the feces and pyrosequenced the microbial 16S region to characterize the bacteria expelled from the gut. I worked with Dr. Girguis’ student Jon Sanders to analyze the resulting data in the program QIIME and carried out principal components analyses to compare the whale gut microbial community to those of terrestrial mammals, discovering that baleen whales have unique and highly diverged gut microbial communities. I have continued to work on these questions with my Harvard colleagues after graduation, adding metagenomic fecal data from many other cetaceans and a range of terrestrial animals to expand our dataset. We theorize that the need to digest large amounts of chitin (in the exoskeletons of krill and copepods) may the driving force behind the divergence in the gut flora of baleen whales.
Summer Research Internship Summer 2010

Advisers: Steve Palumbi & Melissa Pespeni
Projects: I participated in two projects, the first on corals sampled from American Samoa and the second on genome-wide signatures of selection in purple sea urchins along the west coast. I used PCR to amplify genes with known markers to discover that certain corals were new recruits to a reef in a marine sanctuary, demonstrating gene flow between the marine reserve and other reefs. The second project was more extensive; Dr. Melissa Pespeni had used a Restriction Site Tiling Analysis (RSTA) array to identify sites in urchin genomes that differ between Boiler Bay, OR and San Diego, CA populations. I looked for patterns of adaptive variation by expanding her dataset to encompass four additional sites on the west coast. I carried out sample collection in local intertidal zones, extracted genomic DNA from spine samples, amplified the genes of interest using PCR and edited the sequences in the program Sequencher. In the process, I trained a high school student in laboratory and analysis techniques. As published in Pespeni & Palumbi (2013, Molecular Ecology), our study found signatures of selection across the urchins’ range in patterns suggestive of ongoing balancing selection, possibly acting on the urchins’ larval form.

Project: I studied the genetic variation of zebra finch song learning genes for my first laboratory research experiences at Harvard. We sequenced song learning genes from finches sampled on the Australian mainland and a nearby island to look for single nucleotide polymorphisms (SNPs) between the populations. The presence of such polymorphisms would demonstrate divergence in highly conserved song-learning genes between the parent and island populations, hinting at the evolution of different song ‘dialects’ as a possible factor in speciation. Our sample size was too small for significant results, but we did identify a few polymorphisms which may indicate that some divergence is occurring.
