Curriculum Vitae (pdf)

Sheri is interested in how marine microbes interact with one another and their environment, the chemical reactions that mediate such interactions and the resulting impact on global elemental cycles. Her Ph.D. research focused on the impact of virus infections on intact, infected eukaryotic marine microbes and included bioinformatic and flow-cytometric screening for persistent (cryptic) infections and combined molecular, chemical and ecological methods to quantify virus-induced biochemical alterations of phytoplankton cells and the resultant impact on copepod grazing. Sheri joined the Sullivan Lab in August 2014 where her projects include using transcriptomics and metabolomics to explore interactions between model systems of viruses, bacteria, phytoplankton and grazers and developing experimental methodology to quantify the role of marine viruses in trophic transfer of carbon.
