Heather A. Holmes' PhD research focus was experimental investigations to study air pollution, turbulence, meteorology and chemistry in the atmospheric boundary layer. Following her PhD, two visiting researcher positions took her to Asia and Europe where she studied airborne pollen collection and wind energy. She completed her postdoctoral training at Georgia Tech as part of the Southeastern Center for Air Pollution and Epidemiology (SCAPE, www.scape.gatech.edu) working with engineers, atmospheric scientists and epidemiologists to characterize air pollution mixtures and their associated health effects. As part of SCAPE, her research focus was to analyze air pollution and air quality modeling data to better understand and quantify how emission sources combine to impact air quality and provide air quality metrics to epidemiologists for use in health assessments. Her current research interests incorporate numerical weather prediction and chemical transport modeling with field experiments to investigate pollutant accumulation, transport and mixing and provide data for health and public policy assessments.
