Research Interests
Atmospheric Science and Computational Chemistry
The bulk of my research involves the use of numerical models to
study the present state of the atmosphere and its evolution. Of
particular concern is the evolution of ozone in the atmosphere.
In the stratosphere, ozone acts as a shield preventing potentially
lethal ultraviolet radiation reaching the biosphere. In this region
of the atmosphere, ozone has been declining and my research in this
area has focused on understanding the development and future evolution
of the Antarctic Ozone Hole. A significant result of my research
has been to establish the fact that climate change induced by greenhouse
gases will delay the future recovery of the ozone hole despite the
expected decline in halocarbons following the implementation of
the Montreal Protocol.
In the troposphere, ozone is the most irritant of the common air
pollutants and exposure to large concentrations causes inflammation
of the respiratory tract and morphological changes in the lung.
Studies indicate that monthly-averaged ozone concentrations will
exceed 130 parts per billion over large parts of Southeast Asia
towards the end of the century well in excess of recommended thresholds
to exposure. My research has attempted to assess the environmental
impact and economic cost of the present behaviour and the future
evolution of tropospheric ozone and other greenhouse gases. The
strategy has been to couple a two-dimensional chemistry-climate
model to an environmental macroeconomic model. This model is being
used to identify long-term abatement strategies at minimum economic
cost.
On a more theoretical level, I am also interested in calculating,
from first principals, rate coefficients for some of the more important
atmospherically significant reactions.
