Research Interests
Stratospheric aerosol theory; middle atmosphere chemistry and microphysics.
Current Research
Dr. Mills' research has focused on modeling the chemistry and microphysics of the middle
atmosphere, which affect the ozone layer and our climate. His recent published work
suggests that high-energy cosmic rays from dense interstellar clouds caused catastrophic
ozone depletion and mass extinctions in the past, during periods of magnetic reversal on
Earth. His earlier work developed the semi-empirical method for evaluating ozone
depletion potentials, which helped insure that the dramatic depletions in ozone at the
Earth’s poles are correctly accounted for in evaluating substances controlled by the
Montreal Protocol protecting the ozone layer. His work has taken him below the Antarctic
Circle and above the Arctic Circle.
