Research Interests and Current Projects:

Diatom-Bacteria Interactions

Diatoms have an important role in the Earth’s carbon cycle, but they are not alone: the nature of their relationships with other marine microbes determines the fate of their fixed carbon. I aim to use modern molecular and informatics techniques to understand these complex relationships, using model diatom-bacteria associations.

Metagenomics and Metatranscriptomics of Ocean Communities

The advent of novel sequencing technologies has opened up new windows for investigation of community structure and function. Dramatic decreases in sequencing cost-per-base has allowed for the collection of massive community data sets, but the task of extracting meaningful information from these large data presents a challenge. I am developing pipelines for analysis of many environmental samples in order to improve our understanding of biological processes at the genetic and transcriptional levels.
