Dr. Hildemann specializes in air pollution engineering. Her research interests include atmospheric chemistry, characterization of source emissions, dispersion modeling, and indoor air pollutants. She is currently studying the sources, chemistry and fate of organic pollutants, with a focus on aerosols. Major areas of research include investigating the sources and size distributions of indoor particulate matter (including allergens), and characterizing the uptake of water by organic aerosols. Professor Hildemann is a 1991 recipient of the Presidential Young Investigator award, a 1993 recipient of the Office of Naval Research Young Investigator award, and the 1998 recipient of the American Association for Aerosol Research's Kenneth T. Whitby award, recognizing outstanding contributions to aerosol research by an early-career scientist.
