Dr. Arnold is a biochemist who studies natural products produced by marine organisms and terrestrial plants exposed to stressful conditions, such as changing climates, grazing, or infection. His research focuses on plant polyphenolics - especially those from coral reefs, seagrass meadows, and forests - which exhibit promising medical properties.

BIOL 131 Intro to Org, Pop & Ecosyst
This introductory course spans levels of biological organization from basic multicellular microanatomy to organismal physiology and ecology, as understood through the lens of evolution. Course content will be focused around a specific theme determined by the instructor, and will include evolutionary principles of variation, selection, competition and cooperation, and how their operation at different levels of organization accounts for form and function of organisms, communities, and ecosystems. We will investigate homeostasis, reproduction and development as physiological processes that take place within organisms, and as ecological processes that interact with the environment and generate diversity of form over evolutionary time. Finally we will take stock of the existing forms and levels of biological organization and ask how their relationships establish the biosphere in which we live. Three hours classroom and three hours laboratory a week. This is one of two courses required of all Biology majors before entering the upper level. It is complementary to BIOL 132 – Introduction to Molecules, Genes, and Cells, and the courses may be taken in either order.

BIOL 325 Plant Physiology w/Lab
A study of plant structure and function, with emphasis on the flowering plants. Includes plant cells and organelles, mineral nutrition, translocation processes, and hormonal regulation of growth, development, and reproduction. Biochemical and environmental aspects of photosynthesis are emphasized. Six hours classroom/laboratory a week. Prerequisites: One 200-level Biology course. For ENST/ENSC majors only, prerequisite is ENST 162.
