Kristian D. Hajny's research focuses on measuring and quantifying methane and other emissions from sources like power plants, urban areas, and oil and gas basins, often using aircraft-based measurement campaigns. The work combines atmospheric chemistry with data analysis techniques to build more accurate, measurement-based emissions inventories that can complement or check traditional estimates. This research is relevant to understanding air quality and climate-relevant gas emissions from energy infrastructure.
