Gregor-Fausto Siegmund, Ph.D.

As a post-doctoral research ecologist with the US Geological Survey’s Southwest Biological Science Center, Gregor works to understand the environmental variables that influence plant regeneration in the Great Basin and the Colorado Plateau. His research synthesizes existing knowledge to develop new models to forecast successful plant establishment in restoration projects in western US drylands.

Dr. Siegmund is a plant and quantitative ecologist interested in population and community responses to environmental variability. In particular, he is fascinated by how organisms persist under abiotic and biotic unpredictability and uncertainty. In his dissertation, he studied the effect of temporal variability on the ecology and evolution of annual plants.
