Air pollution plagues society in many countries around the world. It ranges from indoor air pollution at the smallest scale, through urban and regional smog, to global climate change and stratospheric ozone depletion. Our research focuses on understanding the atmospheric processes that transport and transform particulate pollutants between their emission and their reception. Experimental, numerical, and theoretical approaches are employed. Focus is on urban and regional smog, and global climate change.

Biomedical Engineering Research
A long-standing interest of our group is employing engineering methods and principles to the understanding of physiological systems. Currently we work on deposition of aerosol particles in human airways and dynamic response of muscles to functional stimulation. Previous enveadors have included work on the urine concentrating mechanism in the renal medulla.
