Research Interests
My general research
is in studying
the composition of the troposphere
using satellite and in-situ observations
(e.g. aircraft and ground-based measurements taken during field campaigns)
in conjunction with regional and
global atmospheric models. I am addressing
the link between
local pollution processes and regional
and global pollution in my
current work. Gases and aerosols
emitted from local human activities,
in addition to natural sources,
might change atmospheric composition on inter-continental or even global
scales coupled through mixing, transport and chemical
transformation. This makes local air
quality a global issue and, as
further consequence, also a factor in
climate change. Air quality issues
are also linked to public
policy applications because many of
the pollutants emitted by human
activity are known to have
detrimental impacts on health and
natural and managed ecosystems with a direct bearing
on human welfare and environmental
quality.
Some of my
current research topics include e.g. the intercontinental
transport of pollution across the Pacific and
how it impacts
regional and local air quality
over North America, the impacts
of boreal wildfires on air
quality and climate, or the
role of emissions
of volatile organic compounds from vegetation on atmospheric trace species such
as formaldehyde or ozone.
The following article in Bridges Online provides a brief overview of my career
path. Bridges is a publication of the Office of Science
