Dr. Gene Tyson is a microbial ecologist whose research applies molecular approaches to understand the structure and function of microbial communities in the environment. During Gene’s dissertation research (University of California, Berkeley with Prof. Jill Banfield) he was the lead author on one of the first studies to use metagenomics. In this work he investigated the metabolic potential and population diversity of microbial communities involved in acid mine drainage (AMD) generation, and demonstrated for the first time that metagenomic data could be used to reconstruct near complete genomes directly from environmental samples. He used these composite genomic assemblies of natural populations to explore microbial evolutionary processes.
Following his PhD, Gene sought more complex microbial communities on which to apply cutting-edge molecular tools with the goal of teasing out general principles in microbial population evolution and ecology. At the Massachusetts Institute of Technology (2006-2009), he conducted postdoctoral research work with Prof. Edward DeLong on the composition, functional potential, regulation, and evolution of complex marine microbial communities at sites around the world’s oceans. A highlight of this research was the use of ‘metatranscriptomics’ to investigate gene expression in microbial assemblage from the Pacific Ocean, demonstrating clear depth-specific signatures in the expression of photosynthesis, carbon fixation and nutrient uptake genes as well as high expression of a number of hypothetical genes. One particularly exciting metatranscriptomic discovery made by Dr. Tyson and a graduate student in the lab was that marine microorganisms express a surprisingly large number of small RNAs, which previously were not thought to play a major role in bacterial and archaeal gene regulation. This is profoundly changing our understanding of gene regulation in the marine environment and microbial communities in general.
