Research Interests

My research focuses on the role of oceans in controlling atmospheric greenhouse gas concentrations. Greenhouse gases such as carbon dioxide, methane, and nitrous oxide can be produced and consumed by various ocean-dwelling microorganisms, and ocean currents can transport these gases over great distances. I am primarily interested in determining the key processes responsible for the distribution of gases in the oceans, as they control the amount of greenhouse gases that are exchanged with the atmosphere. This is important because ongoing and future ocean changes such as oxygen minimum zone expansion, sea-ice loss, melting permafrost, and ocean acidification may alter the amount of greenhouse gases stored and released by oceans, which may accelerate climate change. Understanding the processes driving ocean-atmospheric greenhouse gas exchange will help identify the significance of different oceanic climate feedbacks, as well as potential mitigation strategies to minimize the negative impacts of ocean change.
