Pandis Research Group

Our research areas include the study of multiphase atmospheric chemistry as it relates to air quality and climate change.

The group has two branches:

(1) One in Patra (Greece) in the Chemical Engineering Department of the University of Patras and the Institute of Chemical Engineering (ICE).

(2) One in Carnegie Mellon University in Pittsburgh (US) in the Department of Chemical Engineering and the Department of Engineering and Public Policy. This group is part of the Center of Atmospheric Particulate Studies (CAPS).

 


Control Strategies for Atmospheric Ozone, Particulate Matter, and Acidity.

Air pollution problems have been traditionally treated separately from each other, often resulting in sub-optimal choices of emission control strategies. The air pollution group is developing comprehensive mathematical models describing the interplay of pollutant emissions, atmospheric homogeneous and heterogeneous chemistry, dispersion, and removal processes leading to major air pollution problems. After evaluation against observations, these tools are used for the identification of cost-effective emission controls for the reduction of damages caused by multiple pollutants.


Atmospheric Chemistry and Global Climate Change.

The interactions between the anthropogenic perturbations of the atmospheric chemical composition and climate are investigated in a number of projects. These include studies of the role of atmospheric aerosols in the earth's radiative balance, changes in the oxidative capacity of the atmosphere, the anthropogenic perturbations in the remote marine atmosphere, and the long range transport of atmospheric trace components.


Formation and Properties of Atmospheric Aerosols.

The partitioning of semi-volatile atmospheric aerosol components between the gas and particulate phases is investigated. The role of the organic aerosol components on the ability of atmospheric particles to absorb water is a major focus of this research.
