About ICF
Chris Holder
Science Director, Air Quality Modeling
Chris Holder is an air quality and exposure modeling expert with over 15 years of technical and managerial experience conducting risk assessments for clients at the federal, state, and local levels.
Chris plays vital technical and management roles supporting assessments that span various scales and topics. He has experience with facility-specific emissions and the resulting environmental and health impacts, mobile source emissions and their impacts on metropolitan areas, and quantification and trend analyses of multi-source U.S. emissions and air quality. He manages the development and enhancements of models and tools that enhance quality control; compile, process, and evaluate emissions; and simulate inhalation exposures to air pollutants, among other functions. Chris also has experience in exposure-centered systematic reviews, geospatial analyses, and climatology.
