Brief Bio

Current research focuses on investigating new wildfire observations from the emerging stereo wind and aerosol imaging techniques paring low Earth orbit (LEO) with geostationary (GEO) satellites and GEO with GEO satellites. Her current work comparing stereo observations directly with numerical weather model simulations to diagnose the modeled plume injection or plume/cloud top height and wind velocity, and aerosol properties leverages her research experience with developing data fusion physical techniques to constraining chemical transport model outputs for regional wildfire and air quality applications using satellite-, aircraft- and ground-based observations. Additional research includes advancing the design of air quality data fusion using novel stereo imagining techniques to estimate ground-level PM2.5 mass and speciated exposure metrics over multiple, globally distributed metropolitan areas and surrounding regions, with limited to no ground-based air quality measurement networks, affected by major pollution sources.
