These are the stars that will end up as supernovae, but equally important are the questions how and where they form, and how they live. Their relatively short lives make them the recyclers of the universe, processing hydrogen and helium into the heavier elements, including those necessary for life on Earth. Currently, she is examining the question of distance to Wolf-Rayet (WR) stars, known to be the evolved descendants of these massive stars. Garmany is very interested in science education and has worked for many years with K–12 teachers to bring astronomy into their classrooms.

Barry Osmond

B.Sc. (Hons1), University of New England, Armidale NSW, Australia, 1961; M.Sc., 1963; Ph.D., University of Adelaide, Adelaide SA, Australia, 1965.
Fellow, Royal Society of London, 1984; fellow, Australian Academy of Science, 1978.

Research Interests:
Osmond is a plant biologist with broad interests in photosynthesis, the plant miracle that daily turns air and water into the oxygen we breathe, making possible our bread and wine, fuel and fiber, and simply sustaining all life. Osmond is especially concerned with understanding how plants deal with excess light and other stresses, and how their activities can be scaled up from the leaf to the landscape. Two main areas of current interest are the readily reversible processes of photoprotection, and the slowly reversible processes of photoinactivation that lead to photodamage. The former involve pigment protein transformations in the antennae of photosystem II that lead to the dumping of excess light as heat. The latter involve events in the reaction center of photosystem II that lead to the destruction of core proteins and loss of function. Approaches to these problems use nonintrusive methods of chlorophyll fluorescence quenching kinetics and imaging in vivo, and intrusive studies of chloroplast membrane structure and function in vitro.

Research Interests:
Peterson is a plant ecologist interested in the effects of rising atmospheric carbon dioxide on the mechanisms that maintain biodiversity in terrestrial plant communities.

His interests include the evolutionary implications of such mechanisms, the effect of environmental variability on community structure, and its role in the maintenance of biodiversity. He utilizes established theory to make empirical links between the responses of individuals (physiological and/or behavioral) to competition and environmental variability, and the effects of those responses on community dynamics.
