Atmospheric aerosols play a critical role in both climate change and human health, yet large uncertainties remain in quantifying their impacts across spatial and temporal scales. My research aims to reduce these uncertainties by integrating laboratory experiments, field observations, chemical transport modeling, and data-driven approaches to understand the key physicochemical properties and processes of atmospheric aerosols and their environmental impacts.

In this seminar, I will present an overview of my research that connects aerosol properties and processes to climate and health outcomes. First, I will discuss efforts to constrain historical fire emissions and aerosol radiative forcing using ice-core observations and inverse modeling. Second, I will highlight studies investigating climate-relevant aerosol properties and processes, including aerosol optical properties, mixing states, hygroscopicity, photolytic aging, and temperature sensitivity of particulate matter. Finally, I will describe emerging work linking aerosol composition and physicochemical properties to health outcomes, such as the neurodegenerative disease risks. Together, this work aims to advance a mechanistic understanding of aerosol impacts and bridge atmospheric chemistry, climate science, and environmental health.
