Research Program

My research interests include the elucidation of species concepts of wood-inhabiting basidiomycetes especially those in the genera Armillaria and Laetiporus, which cause major root and heart rot in forests world-wide. These studies encompass the use of characteristics of several types including morphological, genetic, ecological, and molecular to give a dependable species concept. A broad spectrum biosystematic study of the genera and species of the wood inhabiting basidiomycetes is also being persued as a long term program. As a part of this program, wood-inhabiting fungi in Alaska and in the subantarctic islands are being surveyed to determine and compare the diversity and to establish baseline data for use in environmental monitoring. Involvement in pest risk assessments of the importation of raw wood (logs, wood chips, and wood packing material) into North America has been another strong involvement for the past 10 years.
