Sosik is a senior scientist at the Woods Hole Oceanographic Institution, where she explores the roles of microscopic plankton in ocean ecosystems. She received S.B. and S.M. degrees from MIT and a Ph.D. from Scripps Institution of Oceanography at the University of California, San Diego. Recognition of Sosik’s accomplishments includes a Presidential Early Career Award for Scientists and Engineers, a fellowship of The Oceanography Society and a sustaining fellowship of the Association for the Sciences of Limnology and Oceanography. Sosik and co-workers have developed automated underwater cell analyzers that transform scientists’ and resource managers’ abilities to study microscopic organisms that fuel ocean food chains and sometimes produce harmful algal blooms.

Life Sciences

The Life Sciences division seeks to advance the fundamental understanding of life on Earth. The division’s previous initiatives focused on microbial ecology and evolution, including the biogeochemical modeling of marine ecosystems. New programs will expand to all ecosystems, with emphases on eco-evolutionary dynamics and plant biology. All its programs aim to encourage scientific exchange within and between fields and support early-career scientists.
