Research Interests

  • Modeling Biological Systems

  • Terrestrial Plant Ecology


  • BIOL 203: Principles of Ecology

    A study of the interrelationship of organisms and their environment. Emphasis is placed upon levels of ecological organization.

  • BIOL 350: Foundations of Biostatistics

    Quantitative analysis in the biological sciences involves understanding the scientific method, experimental design, sampling theory, graphs, and data analysis and interpretation. Students will develop and test hypotheses using statistics and graphing techniques in computer-based laboratory exercises.

  • BIOL 383: Graduate School & Work Seminar

    The purpose of this seminar is to help seniors through the process of applying to graduate school, and/or determining options for working in biology after graduation. Applications for most graduate programs are due in January or February. By the end of this course, each student should have selected several programs to apply to, contacted the programs and potential advisors, have some understanding of financing for graduate school, and have the majority of their application completed. For students not planning to apply to graduate school, parallel assignments will prepare them to apply for a position as a lab or field technician or research fellow.
