VICKEN ETYEMEZIAN is a doctoral student at Carnegie Mellon University (CMU). He received combined bachelor degrees in physics and engineering from Occidental College and the California Institute of Technology, respectively, and a master's of science in environmental engineering from the Johns Hopkins University. His research has focused on the effects of atmospheric pollutants on sensitive building materials, with an emphasis on dry deposition and surface rain washing. Some of his other interests include policies for sustainable environments in developing countries, urban and remote atmospheric chemistry, contaminant transport in groundwater, and innovative solutions for wastewater treatment.

CLIFF I. DAVIDSON is professor of civil and environmental engineering and engineering and public policy at Carnegie Mellon University (CMU). He is also director of the Environmental Institute at CMU. His main research interests involve atmospheric pollutants, focusing on the way particles and gases are transported through the atmosphere, the mechanisms by which particles and gases deposit from the atmosphere onto different types of surfaces, and historical trends in air pollution levels. His main educational activities include developing material that can be used broadly in basic science and engineering courses to increase student awareness of environmental issues. Address as for Etyemezian.

SUSAN FINGER is on the faculty of the Civil and Environmental Engineering Department at Carnegie Mellon University.
