Professional CV 

I am relatively new to the ES faculty, after working in administration for some years previously. I try to bring a different perspective to the Environments Studies Program from my background and experience working in marine ecosystems. I am trained as a traditional biologist with a specialization in ecological physiology, and I have study and published on adaptations of marine organisms to habitats ranging from mudflats to hydrothermal vents.

I thoroughly enjoy fostering the basic understanding of biological principles and concepts, and I work to enrich my teaching with experiences from my fieldwork and research. I teach lower division general education courses in Biology and Environmental Studies, ES entry-level majors courses such as Environmental Studies I and II, as well as, Oceanography and senior and graduate level seminars. And who knows what the future might bring? I look forward to exploring it with our bright and committed SOU students.

Research Interests

California Red Fir (Abies magnifica) grows throughout the Sierra Nevada. A closely related red fir, Noble Fir (Abies procera), grows in the Cascades and Coast ranges of Washington and Oregon. In the Klamath Mountains and Cascades of southern Oregon and northern California grow trees of intermediate morphology. Many botanists have suggested that these intermediates are hybrids.  I am using DNA sequencing to investigate the phylogeny of the red fir complex up and down the West Coast. I hope to use genetic markers from the nuclear, chloroplast, and mitochondrial genomes. These separate genomes are inherited biparentally, paternally, and maternally, respectively, and so potentially allow us to determine which species contributed as pollen donor, egg donor, or both.
