Research Interests

The Broad Goal
Human activities over the last couple hundred years have initiated an unprecedented perturbation to climate and atmospheric chemistry. These greenhouse gas emissions (e.g. CO2, CH4, N2O…) and atmospheric pollutants (NOx, VOCs, aerosols…) are released from a variety of human and natural sources, to which the partitioning is incomplete. Observations of the sources and sinks of these gases are required from a variety of platforms to understand processes, inform mitigation strategies, and the resolve the full scope of their consequences.

Current Project
Methane (CH4) and nitrogen oxides (NOx) emissions from the oil and natural gas supply chain are important to the overall budget, but are not fully understood and affect evaluations of this segment of the energy sector. Offshore oil and gas systems specifically are under sampled, yet comprise nearly one third of oil and gas production. My current research is exploring emissions from these offshore activities through the Flaring & Fossil Fuels: Uncovering Emissions & Losses campaigns: http://graham.umich.edu/f3uel
