    Special Experience

    Dr. Campbell has research experience working with both C3 and C4 vegetation, conducting biophysical and spectral assessments in a variety of forested ecosystems and croplands in both the Northeastern and Southeastern United States. Other study areas include extensive forest decline investigations in the Bohemian Mountains of the Czech Republic, Austria and Germany, boreal forest characterizations in Canada and Eastern Siberia, and many locations throughout Bulgaria. Her research interests include:
    • physiological plant ecology: effect of environmental stress on the plants metabolism (photosynthesis and respiration, carbon allocation, development and growth), bio-indicators of vegetation stress and their spectral expression; relationships among vegetation biophysical parameters and their spectral responses;
    • forest ecology and sylviculture: canopy structure – LAI, phenology, forest stand dynamics, composition and succession;
    • tree physiology: natural and anthropogenic factors causing vegetation stress, tree growth decline and forest damage, physiological processes affected by natural and anthropogenic stress agents, symptoms of forest damage and growth decline.
