Research Interests

AEROSOL · PARTICLES

Aerosol Mixing State

How particle-level composition and mixing state shape aerosol optical properties, aging, and cloud-relevant behavior.

CLOUDS · CCN

Aerosol-Cloud Interactions

How surfactants, phase separation, and surface tension influence CCN activity and cloud droplet formation.

MODELING · DATA

Machine Learning

Connecting particle-scale understanding with regional and global models to quantify aerosol-climate effects.
