My home is in Eugene, Oregon, where I have lived and worked for over 45 years. I was Director and Curator of the University of Oregon Herbarium 1976 to 1993. Since 1993 I have operated the Northwest Botanical Institute, dedicated to research, education, and public service. I specialize in ferns, mosses and liverworts. My focus is on field botany and taxonomy.
