Research
My work focuses on how human and natural drivers shape the chemistry and radiative balance of the stratosphere. I combine climate model simulations, satellite observations, and statistical methods to attribute observed variability to specific mechanisms.
Human influence on the ozone layer detectable by the 1960s
A thought experiment using CESM-WACCM6 and CCMI-2022 ensembles to determine when ODS-induced ozone depletion first becomes statistically detectable.

Limited long-term photolysis of stratospheric organic aerosols
Showing that aged organic aerosols in the stratosphere undergo negligible photolysis, and developing an age-dependent scheme to correct CESM model bias.

Inferring stratospheric NO₂ photolysis rates from satellite observations
Deriving J(NO₂) globally from MIPAS/Envisat data and demonstrating albedo-driven photolysis enhancement over polar ice and snow.
