The Simons Foundation is now accepting applications for its Simons Early Career Investigator in Marine Microbial Ecology and Evolution Awards. Microbes inhabit and sustain all habitats on Earth. In the oceans, microbes capture solar energy, catalyze biogeochemical transformations of important elements, produce and consume greenhouse gases, and provide the base of the food web. The purpose of these awards is to help launch the careers of outstanding investigators who will advance our understanding of marine microbial ecology and evolution through experiments, modeling or theory. Projects focusing on the microbiomes of invertebrates or vertebrates or on paleontological records will not be considered this year. Investigators with backgrounds in different fields are encouraged to apply. Applicants must hold a Ph.D. or equivalent degree. She/he must have carried out research in a tenure-track or equivalent independent position for at least one year and no more than eight years (start date between November 2009 and November 2016) and must currently hold a tenure-track, tenured, or equivalent independent position in a U.S. or Canadian institution. She/he must be the principal investigator (PI) or co-PI currently or within the past year on a research grant from a national governmental agency or major foundation. Grants will be for $180,000 USD per year, including indirect costs (limited to 20 percent of modified total direct costs), for a period of three years, subject to annual reviews and continuation of research in areas relevant to the purpose of this program. The deadline for receipt of letters of intent (LOI) is November 6, 2017.
