Holistic Insect Systemantics Laboratory

Bio

I enjoy studying insect diversity and a sharing my knowledge and excitement with others. Over 20 years, I have developed an international research program in insect systematics and collection stewardship. My research program has been continuously funded since 2003, which has helped me to educate graduate and undergraduate students, revitalize the A.J. Cook Arthropod Research Collection, and revise the study of bark beetle systematics.

Current assignment: Teaching 20% | Research 80%

Program Description

Teaching

As an educator, much of my time and resources are focused on advancing the knowledge and skills of my graduate students. I believe that an investment in our graduate students is an investment in MSU. These students provide the intellectual fodder and physical labor, which often leads to innovative and productive research. I have advised eight Ph.D. and eight masters’ students. I also served (and serve) on graduate student committees for several other departments. I encourage students to pursue their own systematic research interests within the context of my research program. This has led to my collaboration on nine non-bark beetle research topics ranging from termites to ants. These collaborations not only benefited my research program and MSU’s reputation, but also broadened my reputation as an insect systematist. I currently teach graduate classes in Taxonomy of Adult Insects and Spider Biology. My philosophical objective in classroom teaching is to strengthen independent thinking among graduate students. To instill this objective, I restructured the taxonomy course and designed the spider class so to incorporate modern pedagogical methods such as learner-centered teaching.

Research

Systematics is the study of organismal diversity, relationships and the classification of these relationships. It forms the foundation for the biological sciences through the creation of a common communication system concerning all life. Without a means to identify a study organism, the replication of biological experiments or the management of pests would not be possible. In addition, knowledge of organismal relationships (phylogenetics) provides a predictive framework for studies concerning species biology, ecology and evolution. My research program focuses on bark beetles (Scolytinae). In general, bark beetles function ecologically as decomposers of wood. However, some aggressive species and, to a lesser extent, benign species kill live trees, especially during periods of environmental stress. These pests cause severe economic and ecological losses, which often equates to millions of dollars. However, efforts to study and/or control this group are hampered by a lack of taxonomic knowledge. Hence my current taxonomic research of tropical bark beetles increases the knowledge of species diversity, the relationships among the species, and results in better means for their identification. Other scientists and diagnosticians use these results to improve surveys for potential pests. In addition, I educate national and international technicians, undergraduates, and graduate students in the identification and systematics of bark beetles. Thereby, perpetuating knowledge of these beetles through space and time.
