The Ward Lab

Welcome

Research in the Ward laboratory concerns the marine and global nitrogen cycle, using molecular biological investigations of marine bacteria and bacterial processes (especially nitrification and denitrification), and measuring the rates of N transformation processes using various isotope approaches. We have ongoing research in the following areas:

  • Nitrogen cycling (nitrification, denitrification, anammox, etc.) in several suboxic zones of the world ocean (Arabian Sea, Eastern Tropical North and South Pacific) and in Chesapeake Bay, Great Sippewissett Salt Marsh, etc.
  • Nitrogen assimilation by phytoplankton and functional diversity of eukaryotic phytoplankton in the world ocean
  • Diversity of functional guilds of bacteria involved in the nitrogen cycle of aquatic systems

Please contact us for more information and for queries about undergraduate, graduate and post doctoral research opportunities.

Aerosols from wildfires can fertilize the oceans

Wildfires can have catastrophic environmental and socioeconomic impacts on land, such as the loss of habitats and biodiversity, air pollution and public health. However, few studies report on the fires’ impact on ocean ecosystems. In a…

Princeton Environmental Research Portal: A Half-Century at the Forefront of Environmental Research
You can now explore the full scope of Princeton’s latest environmental research – plus the University’s legacy of environmental commitment – through a single portal: "Princeton Environmental Research: A Half-Century at the Forefront." The portal was launched on Thursday, Oct 15, 2020. Users will find a video presenting 50 years of environmental research as well as a series of articles documenting Princeton’s historic research contributions in a areas from climate modeling to the future of food
