Research Areas of Interest
BTC 426/EFB 626: Plant Tissue Culture Methods, an upper division/graduate course that introduces plant tissue culture as a foundation for biotechnology research and as a propagation method. This course emphasizes laboratory instrumentation (microbalances, pH meter, autoclave, laminar-flow hood, stereomicroscope and other common pieces of tissue culture laboratory equipment) and basic aseptic techniques for establishing cell cultures, producing transgenic cell lines, and regenerating whole plants. As a semester-long project, students will research, design, and implement a micropropagation system for a plant species of their own choosing.
FOR 481: Introduction to Arboriculture, an upper division course that is required for the Urban Forestry Minor. Intended for students interested in professional arboriculture, as well as students interested in planting, pruning and otherwise caring for their own trees. Intro. to Arboriculture is about trees in close association with people and the built environments they create. We start with some plant physiology, including the various environmental cues that plants use to predict and respond to changing seasons. We then turn to more applied topics like tree planting, pruning, climbing, and above all, safety.
