Curriculum Vitae

 Biography
My professional training is in the field of botany. I have always loved plants, a gift given to me by my mother. My undergraduate training and part of my graduate education was received here at BYU in the Department of Botany and Range Science. I received my Ph.D. from the Department of Environmental, Population, and Organismic Biology at the University of Colorado in Boulder, Colorado. I have taught more than 20 different courses at BYU including Biology 100 and 130. Over my 37 years of teaching at BYU I have taught more than 65,000 students in Biology 100 alone. My first love has and always will be teaching. I have conducted research in the general area of cryptogamic botany with an emphasis on algae, cyanobacteria, and lichenize fungi. Currently, I am curator of the Herbarium of Non-Vascular Cryptogams in the M.L. Bean Life Science Museum. This collection contains more than 100,000 specimens. My research efforts involve the use of lichens as bio-monitors of air quality and the ecology and restoration of biological soil crust communities. I have published more than 80 papers in scientific journals and authored/edited 4 books including “A Color Guidebook to Common Rocky Mountain Lichens” which was published in 1999. Currently, I serve as director of the Monte L. Bean Life Science Museum and professor of biology.
 Teaching Interests
I have taught more than 20 courses during my career at BYU including more than 65,000 student in Biology 100. I enjoy teaching general biology at both the GE and majors' level as well as field botany, plant kingdom, plant morphology, and graduate courses in lichenology and conservation biology.
 Research Interests
My primary research interests have focused on the use of lichens as bio-monitors of air quality as well as the ecology and restoration of biological soil crust communities.
