Bio

Andrew E. Allen, PhD is a professor in the Microbial and Environmental Genomics Department at JCVI. His research focus is related to genome biology, and comparative and functional genomics of eukaryotic marine phytoplankton. Other areas of interest include molecular microbial ecology and metagenomics of eukaryotic marine microbes and bacteria, molecular and genome evolution, chemical and biological oceanography, microbial metabolism, and bioinformatics. Primary areas of interest are based on understanding the molecular basis of carbon (C), nitrogen (N), and iron (Fe) assimilation and metabolism in marine phytoplankton populations as well as the evolution and ecological relevance of molecular and regulatory and signaling/sensing mechanisms that mediate acclimation responses to nutrient and abiotic stress and control biotic interactions.  Various ongoing physiological and functional genomics based wet-lab, computational, metagenomic, and metatranscriptomic research projects are centered on addressing hypotheses related to controls on the diversity and activity of marine microorganisms.

Prior to joining JCVI, Dr. Allen was a postdoctoral fellow at the École Normale Supérieure in Paris, France and at Princeton University in the labs of Chris Bowler and Bess Ward where he worked on phytoplankton genomics. He received his PhD in Ecology from the University of Georgia under the direction of Marc Frischer and Peter Verity where he studied the molecular basis of nitrogen assimilation in marine bacteria.  Dr. Allen earned his bachelor's degree in Biology and English from Vassar College.
