- Introductory Biology Laboratory I (BY101L): This laboratory accompanies BY101 General Biology lecture. It is an introduction to scientific investigation, cellular processes, and genetics.
- Introductory Biology (BY102): This course presents the second half of the material begun in BY 101. It is an introduction to evolutionary biology, plant and animal diversity, plant biology, and ecology.
- Introductory Biology Laboratory II (BY102L): This laboratory accompanies BY102 Biology II lecture. It is an introduction to developmental biology, plant biology, and vertebrate anatomy and physiology.
Biostatistics (formerly BY201): This course provides an overview of the logistical basics of biological research. Although much of the semester will be focused on data analysis and interpretation of data, we also will cover hypothesis generation, experimental design, and presentation of research results. We strongly stress the ability to use computers to manage, analyze, and present data.
- Limnology (BY333): This course examines the physical, chemical, and biological characteristics and processes of inland waters, with an emphasis on conservation of Florida's rich freshwater resources.
- Conservation Biology (BY444): This course examines the levels at which biological diversity (genes, species, ecosystems) is measured, current patterns in diversity at each level, the approaches taken to conserving each level, and the problems associated with conservation efforts at each level. The end of the course will focus on current conservation efforts and the role of human society in conservation biology, a factor that must be considered for conservation efforts to be successful and to endure.
- Aquatic conservation, disturbances, and community ecology: Many aquatic communities throughout Florida and the world have been impacted by human activities. Habitat removal, nutrient additions, deposition of pollutants, additions and deletions of species, and global climate change affect both the composition of aquatic communities and processes within ecosystems. Concurrent with these human-induced changes are natural disturbances, such as drought, fire, floods, and hurricanes. I am interested in the effects of natural vs. human-induced disturbances on aquatic communities and food webs, the resiliency of communities to disturbance, and aquatic restoration.
- Invasions of exotic species: Although species invasions are intimately linked with aquatic conservation, disturbances, and community ecology, invasion ecology presents its own set of interesting questions, problems, and processes. Many dramatic invasions have occurred within the last few decades, such as the invasion of the zebra mussel into the Great Lakes and its subsequent spread. It is likely that the occurrence of invasions will increase as communities become more disturbed and connected. I am interested in the invasibility of ecosystems and the ecological characteristics of invasive species.
