Christian Hogrefe pursued his undergraduate studies in physics at the Universities of Regensburg and Heidelberg (Germany) from 1991 to 1994. He then took advantage of an opportunity to study abroad which brought him to the Department of Earth and Atmospheric Sciences at the University at Albany where he stayed through 2000 to obtain his M.S. and Ph.D. From 2000 to 2011, he worked as air pollution meteorologist and research scientist at the New York State Department of Environmental Conservation. In these positions, he performed emissions and air quality modeling to support the preparation of state implementation plans and provide guidance for air quality forecasting. In parallel, he held adjunct appointments at the Atmospheric Sciences Research Center and led research projects modeling the impacts of climate change on air quality, integrating observations and model output for long-term air quality characterization, and implementing an experimental ensemble air quality forecasting system. In 2011 he joined EPA where his primary research is on the evaluation and application of CMAQ as well as the evaluation and intercomparison
of air quality models on regional-to-hemispheric scales through international collaborations.

Area of Expertise: Christian Hogrefe’s core expertise is in the application and evaluation of air quality modeling systems and the analysis of atmospheric measurements. Past and present research interests include the evaluation and intercomparison of air quality models on regionalto-hemispheric scales, the integration of air quality observations and long-term air quality model predictions for potential use in health impact studies, and the use of photochemical models for real-time air quality characterization.
