RESEARCH AND TEACHING INTERESTS Research interests include: Differentiated plant tissues and production of secondary metabolites especially terpenoids, bioreactor development for differentiated tissues, downstream processing and scale-up for improving bioprocesses for the production of secondary products from cultured plant tissues especially roots, and more recently, algal biofuels. I lead the Interdisciplinary Plant Research Group, composed of engineers, biochemists, plant biologists, and physicists, who work on challenging problems in both the applied and basic plant sciences that cross disciplines. Teaching activities have included: Development and implementation of new advanced courses in Protein Purification and Downstream Processing (taught 1986-2001), Scale-up (team taught for 2 years). I currently also teach two plant courses to undergraduates, Plant Diversity and Plant Morphology and Development, Plant Physiology, and graduate level Topics in Advanced Plant Physiology, Journal Club in Biology and Biotechnology, Professional Ethics in Life Science Research, and Advanced Applied Biology. I have developed, piloted, evaluated, and disseminated numerous lab videos in Cell Biotechnology for grades 8-college. These were, but no longer are, on the market.   PUBLICATIONS: (Bold, undergraduate co-authors; und, graduate student co-authors)                                                                 REFEREED PAPERS:
