Education
B.S. in Botany (magna cum laude), University of Michigan, 1975
Ph.D. in Biology, Environmental, Population and Organismic Biology, University of Colorado, 1980
Postdoctoral Fellowship, W. K. Kellogg Biological Station, Michigan State University, 1980-1981
Research Interests
Reproductive biology of rare plant taxa of dune ecosystems, particularly the Great Lakes and Atlantic shorelines; multi-species approaches and application of GIS to management and conservation biology. Ecological and evolutionary consequences of plant breeding systems. Plant ecology with emphasis on plant reproductive biology along elevational gradients in the Colorado Rocky Mountains and in response to grazers at high altitudes. Gap-phase dynamics and forest succession. Possible economic applications for a pestilent weed of the southeast.

Current Projects
We have completed work with National Park Service 2001 Natural Resource Preservation Program, Threatened and Endangered Species, for “Habitat assessment using remote sensing data: Restoration methodologies for a federally threatened plant of coastal shorelines, seabeach amaranth (Amaranthus pumilus, Amaranthaceae).” The work was focused at Cape Hatteras, Cape Lookout and Assateague Island National Seashores and our final report is available:
