Website: http://vegathurberlab.oregonstate.edu/ My research uses a combination of molecular and bioinformatic methods to explore intractable host-microbe interactions that are invaluable to our understanding of microbial ecology, symbiont evolution, and the impact microbes have on their host and the world. At OSU, my research focuses on genomic variation in the population of bacterial symbionts that have been found associated with multiple cnidarian hosts. Using phylogenomic and co-divergence analysis, we will be able to learn more about the evolution and transmission of these symbionts. |

Website: https://microbiology.science.oregonstate.edu/content/dr-rebecca-vega-thurber My research focuses on the interface between viruses, their microbial hosts, and human-driven changes in marine nutrient regimes. I am particularly interested in the ways that viruses modify the metabolic activities of the microbes that they infect through the use of auxiliary metabolic genes, or "AMGs". These genes engineer microbial metabolism to better suit viral replication and can alter the way that microbes utilize key macronutrients, including nitrogen. The goal of this research is to understand how specific genetic aspects of viruses contribute to cellular metabolism to better predict how microbial communities respond to transient and sustained eutrophication. |

Website: https://microbiology.science.oregonstate.edu/content/thomas-sharpton My current research interests lie in disease ecology and the associations of infections with microbiome dysbiosis. The role of microbiomes in the development, health and survival of wildlife is largely unknown. In ungulates, and bovids in particular, juvenile survival is critical to population performance. My research will determine the patterns of gut and nasal microbiome development in African buffalo calves and how these relate to their growth, development, survival, and disease susceptibility. The results from this study will improve our understanding of the links between microbiome variation and wildlife population health. |

Website: www.vegathurberlab.wixsite.com/microbiology/team; www.hannah-epstein.com My research interests are focused around coral reef microbial ecology and its role in ecosystem health and climate resilience. In the Vega Thurber Lab, I examine the effects of shifts in nutrient subsidies on the health and resilience of corals through a microbial lens. With the aim to identify land-sea connections in biogeochemical cycling, I hope to discover whether land conservation activities can bolster the health of adjacent reef habitats, providing critical information for future environmental management initiatives. |

Website: http://microbiology.science.oregonstate.edu/content/thomas-sharpton I am interested in the interactions between symbiotic or pathogenic microbes and their hosts. I currently have a joint appointment in the Sharpton and Bartholomew Labs. I am leading the development of a gut microbiome core facility in the Sharpton Lab. This facility serves research programs across the nation by applying cutting-edge DNA sequencing and data analytic approaches to discern the biodiversity and composition of gut microbe samples produced as part of an experiment. In the Bartholomew Lab, I utilize molecular biology techniques to study the myxozoan parasites that affect the health of salmonid populations. |

Website: http://microbiology.science.oregonstate.edu/dr-stephen-giovannoni My research is focused on how genetic code expansion enables augmented metabolism and gene evolution in marine microbial ecosystems. Currently, I am examining the taxonomic range and niche preference of marine microbes capable of genetic code expansion, as well as under-explored pathways for carbon and nitrogen metabolism affected by this mechanism. |

Website: http://microbiology.science.oregonstate.edu/dr-stephen-giovannoni My research is sponsored by Simons Foundation International and is part of the BIOS-SCOPE initiative to understand carbon cycling in the Western Sargasso Sea near Bermuda. My work focuses on the oxidation of dissolved organic matter (DOM) by major groups of planktonic bacteria, including streamlined cells such as SAR11. I employ a combination of approaches, including genomics, experiments with cultured cells, chemical and biochemical measurements, and field studies to identify carbon oxidation pathways. One of the key problems I am trying to understand is the relationship between the reactivity of organic carbon compounds, which determines their half-life in the oceans, and specialized metabolic pathways that have evolved in bacteria for DOM oxidation. My research includes work with co-cultures of phytoplankton and bacteria to understand this early and fundamental step in the global ocean carbon cycle. |

Website:http://microbiology.science.oregonstate.edu/content/thomas-sharpton The gut microbiome is a complex and dynamic community with an incredible metabolic potential. The makeup of the microbiome (i.e., its constituent species and their genes) is influenced by multiple processes including selection by the host, interactions between the microbes, and (my focus) exposure to environmental compounds such as toxins and drugs. The metabolic capabilities of the microbiome influence how such environmental compounds are processed within the host: potentially mitigating or exacerbating toxic effects. My goal, using observational studies in humans and experiments in model organisms, is to ascertain how the environment influences the metabolic potential of the microbiome, and in turn, how the microbiome alters the effects of environmental compounds on the development and health of the host. |
