The Keutsch Group at Harvard University is looking for a Postdoctoral Fellow in Atmospheric Science. The candidate will conduct laboratory experiments focusing on heterogeneous halogen and nitrogen chemistry on organic and biomass-burning aerosols under stratospheric conditions. This research aims to determine reactive uptake rates and other parameters to characterize these processes, integrating results into models of stratospheric chemistry, particularly concerning ozone. The fellow will also engage in stratospheric airborne field campaigns, collecting aerosol samples for microanalysis. Opportunities for collaboration across laboratory, field, and modeling components of a larger research program are available, as well as mentoring graduate and undergraduate students.
