Research Interests

My scientific interests mainly lie with understanding the chemistry and dynamics of the middle and upper atmosphere. I currently work on development of global models of the terrestrial atmosphere, including the Whole Atmosphere Community Climate Model, part of the Community Earth System Model (CESM - website). This work is combined with satellite data analysis to understand variability of atmospheric composition, including studies of the influence of green house gas trends and variable solar forcing. I am co-investigator on the TIMED mission, and was guest investigator on the SNOE mission.
