b	Linda E. Graham Professor of Botany Ph.D. (1975) University of Michigan, Ann Arbor Office: 211 Birge Hall Phone: 608-262-2640 Email: lkgraham@wisc.edu Evolutionary origin of land plants; biology of algae and bryophytes; aquatic molecular microbial ecology

	blank	Current lab projects: We are defining and comparing physiological traits of modern bryophytes and charophycean algae in order to: better understand these organisms' modern ecological roles infer the traits of earliest land plants interpret the ancient microfossil record model charophycean and bryophyte impacts on ancient global C-cycling link with genomic studies to understand biochemical, structural, and reproductive transformation series associated with the origin and early diversification of land plants design habitat restoration strategies and technological applications design planetary terraforming strategies As part of the UW-Madison NSF-sponsored LTER North Temperate Lakes Microbial Observatory, we use molecular methods to: characterize the structure and function of prokaryotic communities associated with freshwater algae evaluate newly-isolated protists, including taxa new to science, that illuminate early eukaryotic diversification and the impacts of endosymbiosis In an engineering collaboration, we are expanding our past studies of periphytic green algae into biotechnological applications. We are evaluating methods for using natural, but nuisance periphyton communities to reduce nutrient pollution, while at the same time producing useful materials to subsidize operational costs.
