The key objectives are to: (i) determine the impact of viruses on sediment metabolism, (ii) quantify the influence of viruses on microbial sulfate reduction rates, and (iii) elucidate the interactions between sulfate reducing microorganisms...
- This National Science Foundation Geosciences Program (CFDA 47.050) Project Grant award of $650,992 to North Carolina State University supports research to assess the role of marine bacteria and viruses in producing and cycling vitamin B1 and related compounds in the surface ocean. The 3-year project will conduct laboratory experiments to estimate the fluxes of these vital compounds from key bacterial groups and the impacts of temperature changes, which are critical for understanding plankton...
- This $400,000 Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences (CFDA 47.049) program supports research to model the complex dynamics of viruses and bacteria in ancient ocean-like environments. The project aims to identify "keystone" viruses that significantly influence microbial community structure and biogeochemistry in these stable, oxygen-free lake ecosystems. The research will develop innovative mathematical methods to predict...
- This federal Project Grant award of $224,921 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to investigate the ecological significance and impact of viral infections on sulfate reducing microbial communities. The primary objectives are to: (i) determine the impact of viruses on sediment metabolism, (ii) quantify the influence of viruses on microbial sulfate reduction rates, and (iii) elucidate the interactions between sulfate...
- The National Science Foundation (NSF) awarded a $815,899 Project Grant under the Geosciences (CFDA 47.050) program to the University of Miami's Rosenstiel School of Marine and Atmospheric Science (RSMAS) for a project titled "Unraveling the Ecological and Evolutionary Drivers of Marine Giant Virus Community Dynamics". The project aims to elucidate the ecological and evolutionary determinants of marine nucleocytoplasmic large DNA viruses (NCLDVs), commonly known as "giant...
- This federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) is for a collaborative research project titled "Revealing RNA Virus and Host Population Dynamics Across Marine Oxygen Minimum Zones." The $630,389 award, effective September 1, 2025 through August 31, 2028, will enable researchers at the Woods Hole Oceanographic Institution (WHOI) to uncover previously unknown RNA virus populations within oxygen-depleted marine systems and...
- This $408,738 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to investigate the effects of SUP05 bacterial cells and the viruses that infect them (phages) on nitrogen cycling in marine oxygen minimum zones. The project is led by the University of Washington, and aims to detail the combined impact of SUP05 cells and their associated phages on nitrogen transformation and loss processes in these ocean regions. Through a...
- This National Science Foundation (NSF) Project Grant award under the Biological Sciences (CFDA 47.074) program provides $240,000 over 3 years to fund a postdoctoral fellowship focused on understanding how climate change-driven shifts in environmental conditions, such as increasing salinity, affect viral activity and its influence on microbial host genomes and phenotypes. The research aims to explore the large-scale impacts of these changes on microbial evolution and global biogeochemical...
This Project Grant award for $699,493.00 from the National Science Foundation's Geosciences program (CFDA 47.050) supports research at the University of North Carolina at Charlotte to study the role of viruses in microbial carbon cycling at deep-sea hydrothermal vents. The key objectives are to identify the diversity, mechanisms, and rates of virus-induced carbon cycling in this deep ocean ecosystem. The research combines metagenomics, stable isotope probing, and microscopy techniques to reveal how viruses infect microbial primary producers and release organic carbon into dissolved and particulate pools. This will help address critical gaps in understanding the dark ocean's carbon cycle. The award runs from September 2025 through August 2028 and involves mentoring postdoctoral and undergraduate students, as well as creating media products to share scientific discoveries about "viruses in the wild" and inspire public interest in deep-sea exploration and microbial oceanography.
