Summary of research
My research interests are in the areas of plant biogeography and systematics. My current work focuses on the ecological and
evolutionary dynamics of rare plants in the genus Astragalus (Fabacaeae). This work includes testing new methods for
quantifying range-sizes at multiple scales, and comparative statistical approaches aimed at elucidating phylogenetic patterns
of rarity in the group. I also conduct rare plant monitoring and population level studies aimed at detecting relevant spatial
scales of ecological processes affecting populations.
I am also a Director of the Redwood Science Project, and the Science Programs Director of the Northcoast Mathematics and
Science Initiative. These projects seeks to enhance the delivery of high-quality K-12 science and math instruction in seven
counties of northwest California. My work includes both program development and evaluation, and research on science teaching.
Current research focuses on three areas: 1) factors influencing science and math majors choices to join the teaching profession, 2)
the professional development of science teachers via the Japanese Lesson Study model, and 3) assessment of new curricula on the
success and retention of environmental resource engineering students.
