Jennifer Brum

Postdoctoral Associate , Dept. of Ecology & Evolutionary Biology

Jennifer arrived January 2010 from the University of Hawai‘i where her PhD included examination of viral impacts on organic matter cycling, viral communities in a hypersaline lake, and the development of new approaches to separate and identify aquatic viruses. At TMPL, she is currently working on several projects including: (i) studying viral ecology and metagenomics in the Southern Ocean through her NSF Postdoctoral Fellowship in Polar Regions Research, (ii) developing targeted viral metagenomics methods to specifically examine the genomes of wild viruses that contain genes of interest, and (iii) examining morphological traits of viruses in the global oceans through the Tara Ocean Expedition.
