Atmospheric particles affect radiation and clouds, while their formation and evolution depend on chemistry and meteorology. Understanding these coupled processes is central to assessing proposed climate interventions and the air-quality changes that may accompany them.
Published foundation
My collaborative work includes simulations of stratospheric particles and the processes that control their size distributions. In a 2026 Environmental Research Letters paper, we examined sulfur dioxide and accumulation-mode sulfuric-acid injection using CESM2 and GEOS-Chem with advanced particle microphysics.
This work connects aerosol process modeling to a broader climate question: how do assumptions about particle formation, growth, and loss affect an intervention’s modeled performance? My contribution to this research complements my first-author work on atmospheric particle formation and cloud condensation nuclei.
Next questions
I am interested in how particle morphology and microphysical evolution affect optical properties and atmospheric residence, and in efficient ways to represent those processes in larger-scale models. A useful first step is to compare simplified representations against explicit microphysics, with attention to the conditions where their predictions diverge.
A longer-term direction is to connect climate and air-quality scenarios with exposure assessment. That work would examine multiple outcomes and uncertainties rather than evaluating a proposed intervention by a single global metric. These are research questions and proposed modeling directions, not evidence that an intervention is safe or effective in practice.
