Sarah Kopac, a Ph.D student in Professor of Biology Fred Cohan’s lab, has won a $20,000 NASA grant for research on ecological aspects of bacterial evolution in Death Valley National Park. The grant, announced Jan. 11 by the Connecticut Space Grant College Consortium, will support Kopac’s study of Bacillus subtilis, a bacterium commonly found in soils that can endure extreme conditions, such as high heat levels. Kopac, a third-year Ph.D candidate, is focused on identifying bacterial species that evolved within a gradient of salty soils – part of a broader effort to understand how ecological factors influence the spawning of…
