Biographical Sketch

Jeff Hill received his PhD in Botany from the University of California, Riverside in 1989. After a post-doctoral fellowship at the University of Georgia, he joined the faculty in the Department of Biological Sciences at Idaho State University in 1991. His research initially focused on understanding patterns and processes of floral evolution, particularly through comparative studies of development at the phenotypic level. Along with several faculty collaborators, he and his students have more recently focused on the functional and developmental biology of alternation of generations in the non-seed plants, relying mainly on the model fern Ceratopteris (http://www.c-fern.org/). Current work with Ceratopteris is intended to advance our understanding of free-living fern gametophyte carbon metabolism. This work poses a number of interesting problems since plants are capable of simultaneous carbon uptake from their environment and carbon fixation by photosynthesis, and whole plant carbon dynamics have feedback effects on light sensitivity and labile sex expression. This work will provide a better understanding of the functional ecophysiology of the gametophyte generation of this model fern, and by extension, the biology of many fern allies with similar life cycle characteristics. Better understanding of land plant gametophyte biology during a period of global change seems especially prudent.

Jeff is also interested in the development and implementation of effective practices in university life science education. For the last several years, he has participated as a co-principle investigator in a National Science Foundation graduate fellowship program (http://www.gk12.org/) intended to foster improved science communication skills in graduate fellows through instructional partnerships with regional K-12 schools in southeast Idaho (http://www.isu.edu/departments/gradk12/).
