Postdoctoral Researcher

Employed By

A NASA Postdoctoral Program (NPP) Fellow is not an employee of any office or agency. The fellow has a guest appointment at JPL. ORAU currently administers the appointment.

Biography

My research interests are focused on remote sensing of plant-environmental interactions across spatiotemporal scales. I apply measurements from in situ, tower, airborne, and spaceborne instruments, including solar induced fluorescence (SIF), reflectance spectroscopy, and lidar to track plant biogeochemical processes and structural properties. Much of my recent work has focused on Arctic-Boreal ecosystems and evergreen needleleaf forests, though I am generally interested in a broad range of natural and managed ecosystems. Currently, I am working on evaluating the impact of cloud cover and direct/diffuse light conditions on the relationship between SIF and photosynthetic phenology across the evergreen needleleaf forest domain. I am also interested in the effect of canopy structure on radiative transfer in plant canopies and how that influences spectral signals of plant function.
