Teaching
ESPM 3612/SOIL 5611 Environmental Soil Biology
This course is an introduction to life in the soil and the properties of microorganisms that impact soil fertility, structure, and quality. We go over the major groups of soil organisms, the nutrient and metabolic requirements of those organisms, and biogeochemical cycles. Symbiotic plant/microbe associations and their role in sustainable agricultural production are discussed, as well as other microbial ecological considerations. We then go over current issues in soil biology including bioremediation approaches, sustainable agriculture, and global environmental change. In addition, this course is listed as writing intensive and students will write a literature review and get lots of practice reading and critiquing primary literature. This is a mixed grad/undergraduate course.
GCC 3031/5031 The Grand Climate Challenge: Creating and Empowered Movement for Change
This is a multidisciplinary course and our teaching team includes Julie Nerbonne, an adjunct professor in the Department of Fisheries and Wildlife and Director of Minnesota Interfaith Power and Light, and Dr. Teddie Potter, a professor in Nursing. We overtly model how to create an interdisciplinary movement. This is a project-based course where we teach students the science and tools to power the work that they are passionate about. We teach them how to navigate a challenging societal landscape with excitement, and how to bring their own expertise to the table. We work by their sides as they develop community action projects aimed at reducing carbon emissions, and knowledge projects to research the facts on a chosen climate impact.

SOIL 8123 Research Ethics
This is a required graduate level course taught every 4 years, covering all aspects of ethical behavior and research practices. We lead this as a discussion based course focusing on case studies. (We are always looking for your new stories to add and will hold them confidential and/or will remove personal information!)
ESPM 1002 Transfer Orientation Seminar
This is a 1 credit seminar for orientation and career development of undergraduates transferring into the Environmental Science, Policy, and Management major.
CFAN 1501 Biotechnology, People, and The Environment (Taught in 2018-2019)
This is an introductory level course presenting many aspects of biotechnology, and how biotechnological advances deserve consideration of ethics and societal value. This is a discussion and engaged learning course where students actively debate and explore the issues.
Research
My research generally lies in understanding ecosystem scale processes through the lens of soil microbial ecology. Soil microorganisms are important drivers of soil quality and ecosystem function, depending both on local microbial adaptation and on interactions with plants and other soil biota. Basic characteristics of soil microbial community growth, composition, and activity can be important indicators of soil quality, sustainability, and soil recovery to disturbance. I’m especially interested in how soil microbial community dynamics can inform our understanding of ecosystem functions such as carbon cycling and sustainability under global change and other human influences.
