Tanja Bosak

Associate Professor

Tanja’s laboratory uses experimental geobiology to explore modern biogeochemical and sedimentological processes in microbial systems and interpret the record of life on the Early Earth.

Tanja Bosak was born in Croatia and graduated from the Zagreb University with a degree in Geophysics. After a summer of research at JPL and a short stint as a meteorologist at the Zagreb Airport, she moved to the California Institute of Technology in Pasadena, where she studied signatures of microbial processes in ancient sedimentary rocks and earned a Ph.D. in Geobiology. She spent two years at Harvard as a Microbial Initiative Postdoctoral Fellow, joined the Department of Earth, Atmospheric and Planetary Sciences at MIT in 2007 and is now an associate professor of Geobiology.
