Lisa Grubisha joined the Bruns lab in August of 1998 as a first year PhD student. At Oregon State, Lisa studied the genus,Rhizopogon. Rhizopogon is a hypogeous fungal genus that is ectomycorrhizal with members of the Pinaceae. Currently the systematics of this very large genus is not well understood. She re-examined sectional relationships and species concepts in this genus using phylogenetic analyses of nuclear ribosomal internal transcribed spacer and large subunit sequence data. Alexander Smith and Sanford Zeller's 1966 publication, Memoirs of the New York Botanical Garden: A Preliminary Account of the North American Species of Rhizopogon, served as her working hypothesis for testing sectional relationships and species concepts.
Lisa completed her PhD and graduated from Berkeley in May 2005. Lisa worked as a Post Doc in Lee Taylor's lab and with Matt Olsen at the University of Alaska in Fairbanks from June 2005 until April 2007. She then moved on to Post Doc in Peter Cotty's lab at the USDA in Tucson AZ, working on a population genetics project on Aspergillus flavus. In 2011, Lisa started another Post Doc at the Centre College in Danville KY.
