The Center for Atmospheric Particle Studies, located at Carnegie Mellon University, Pittsburgh PA, consists of five interwoven research groups directed by faculty members associated with five academic departments (Chemistry, Chemical Engineering, Civil and Environmental Engineering, Engineering and Public Policy, Mechanical Engineering) and two colleges (the Carnegie Institute of Technology and the Mellon College of Science).
CAPS research goals is to is to substantially advance the state of knowledge concenring fine particulate matter, to provide policy-relevant research and to participate directly and actively in the evolution of environmental policy related to particulate matter.
