The oceans are the last wilderness of planet Earth. We have a deep appreciation of the oceans’ role on climate and the carbon cycle, and as enormous reservoirs of biodiversity - from microbes to whales. Yet, the oceans are changing under the influence of humans in ways that we do not fully understand: warming, acidification, deoxygenation, overfishing.

In our group we work to understand how physics, chemistry and biology come together to regulate ocean ecosystems, and in what direction they may change in the future. We are particularly interested in the cycles of oxygen and nitrogen; the ecology of the ocean’s mesopelagic zone; and the role of animals - from zooplankton to fish - in the marine ecosystem. Our research tools range from global observations to theoretical and numerical models of ocean biogeochemistry and ecology.
