Population Dynamics, Quantitative Ecology and Fish Ecology. Compensatory effects of individual physiology and behavior on population change. Interactions among life history, environmental fluctuation and landscape alteration on population growth in a wide range of taxa.
Behavioral ecology of mammals, with a focus on bats. Understanding how ecological, evolutionary, and behavioral factors influence the structure of acoustic communication signals. Behavioral context and function of social calls in a variety of species. Ecology of bats and other mammals in the Great Plains.
Physiological ecology, seasonality, biological rhythms. Physiological and evolutionary mechanisms regulating life-history transitions in seasonal environments. Trade-offs between physiological systems, particularly between energetic investment into reproduction and immune function (as a proxy for survival). Identification of selective forces acting to favor precise timing mechanisms, fitness value of functional endogenous clocks.
Animal Population Dynamics and Ecology, Animal Behavior, Evolutionary Biology, and Systematics. Research emphasis on eagles and other birds of prey with additional interests in many groups of animals including amphibians and reptiles, aquatic invertebrates, and fossil groups, particularly ammonites. Also interested in science education, learning, and curriculum development.
Physiological ecology. Physiological mechanisms underlying life-history strategies, with an emphasis on understanding the hormonal and cellular mechanisms of aging in birds. Current research is focused on examining how variation in stress responsiveness and exposure to stressors influences telomere dynamics.
Assistant Professor of Practice
Coordinator of General Biology Labs (BIOL 150L and BIOL 151L); Research Interests - Wildlife Ecology; Influence of trophic feedbacks among herbivores, plant communities and soil nutrients on plant and animal population dynamics and spatial pattern formation. Affect of human disturbance on animal populations. Conservation Biology
Research Assistant Professor
Wetlands. Plant-soil-water interactions, biogeochemistry, rhizosphere effect, ecological restoration, remediation of polluted soils, phytostabilization, elemental cycling, and trophic transfer.
Lecture in Human Anatomy & Physiology, Comparative Chordate Morphology, and Herpetology. Interests/education focus include ecology, animal behavior, evolution, and conservation biology.
Science education, especially in post-secondary science classrooms. Research focus is on student learning and understanding in undergraduate science classrooms. Other interests are knowledge retention and curriculum development at the undergraduate level and teacher retention/recruitment and curriculum development at the secondary level.

Elemental uptake by wetland plants associated with hot springs. Metal tolerance in wetland plants. Natural and constructed wetlands for improvement of water quality. Wetlands for phytoremediation and phytostabilization of mine wastes.
Associate Professor and Head
Physiological and evolutionary ecology. Effects of maternal physiological state on allocation of resources to young, and how these investments affect offspring growth, survival, and behavior. Research approach spans levels of organization, from physiological mechanisms to population processes.
Cell cycle regulation and cell motility in cancer. Changes in gene and protein expression as cancer becomes more aggressive, and the molecular mechanisms driving the changes. Identification of pharmacological targets
Pre-Health Professions Advisor/Lecturer
Advise pre-medical, pre-optometry, pre-dentistry, and pre-chiropractic students. Assist students with course planning and gathering information on admission requirements for specific professional schools they are considering following their graduation from NDSU. Lecture in UNIV 189, Skills for Academic Success.
Animal physiology/Endocrinology. Control of growth, development, and metabolism in vertebrates. Delineation and regulation of hormonal signaling systems, including control of gene expression.
Evolutionary Ecology of Native and Rare Fishes. Contemporary evolution of fish populations in response to novel environments. Establishment of new populations and the implications for host-parasite associations. Conservation biology, human-wildlife interactions.
Plant Evolutionary Ecology. My research focuses on understanding the ecology and evolution of natural plant populations. In particular I am interested in the evolution of plant reproductive traits, the role of local adaptation and the ecological genomics and population genetics of plant responses to environmental change.
