Hi, I'm Tala Awada, professor of plant ecophysiology in the School of Natural Resources.

I teach in the areas of forest and grassland ecology and plant ecophysiology. I am particularly interested in studying the responses of plants and ecosystems to environmental stresses and climate change. Such studies are necessary to better understand and manage our ecosystems.

The main focus of my research has been on determining the ecological impacts of woody species expansion into semi-arid grasslands and riparian areas in Nebraska. I have been conducting several studies on the functional characteristics of dominant grasses, trees and shrubs in Nebraska and the Great Plains. A number of my graduate students have also been focusing on the development of broad-spectrum stress-tolerant plants. In addition to my work in Nebraska, I have been collaborating with several researchers in Greece to determine the impacts of climate change on Mediterranean pine forests.
