Research Interests
Plant Evolutionary Genetics
Research Summary
Our laboratory is interested in
studying the short and long term effects of inbreeding on
populations and the process of evolution. Flowering plants are
excellent models for this question because they display broad
variation between complete outcrossing and self-fertilization.
Current research focuses on three major themes: 1) the evolution
and breakdown of self-incompatibility in plants; 2) inbreeding and
the process of incipient speciation; and 3) the conservation
genetics of endemic species. In each of these areas, my lab employs
polymorphic genetic markers, studies in natural populations, and
manipulative greenhouse experiments to elucidate the evolutionary
processes that maintain or transform genetic diversity in the
wild.
Prospective graduate students:
I am currently accepting graduate students with interests in population biology, ecology, evolution, and genetics. Graduate students have the option to work on some of the lab's organisms (e.g. Leavenworthia), but are also free to explore their own ideas and interests in other systems. Interested students should contact me via email at jwbusch@wsu.edu to discuss the possibility of joining the lab.
