Bosak’s work integrates microbiology, sedimentology and stable isotope geochemistry into experimental geobiology to ask how microbial processes leave chemical, mineral and morphological signals in sedimentary rocks. Her lab uses this approach to explore modern biogeochemical and sedimentological processes, interpret the coevolution of life and the environment during the first 80% of Earth’s history, and look for signs of past life on Mars. For this work, and her work with graduate students and undergraduates, Bosak received the Subaru Outstanding Woman in Science award from the Geological Society of America (2007), the James B. Macelwane Medal from the American Geophysical Union (2011), the Edgerton Award for young faculty at MIT (2012), the Undergraduate Research Opportunities for Undergraduates Mentor of the Year award from MIT (2012) and the Award for Outstanding Contributions and Dedication to Geobiology and Geomicrobiology from the Geobiology and Geomicrobiology Division of the Geological Society of America. Bosak is a fellow of the American Geophysical Union (2011), a participating scientist and a member of the Project Science Group on Mars 2020 rover mission.
