Meet Tanja Bosak, PhD

In October 2010 Dr. Bosak presented a SftPublic lecture with Alex Petroff (a doctoral student at that time) on the Evolution of Photosynthesis Alex Petroff subsequently received his PhD from MIT and went on to become a Presidential Fellow at Rockefeller University.


Tanja Bosak, PhD. is Hayes Career Development Associate Professor in the Department of Earth, Atmosphere and Planetary Sciences, Massachusetts Institute of Technology. Professor Bosak's research is concerned with microbial fossils that reveal the parallel evolution of life and the environment. The Bosak Lab conducts experiments on modern microbes to test how microbes shape rocks and to understand why microbes produce unique polycyclic lipid compounds that can persist in sediments for billions of years. The Bosak Lab integrates molecular microbiology, geochemistry, sedimentology and modern analytical tools to address the co-evolution of life and the environment on our planet.

Dr. Tanja Bosak was born in Croatia, where she received her B.Sc. from Zagreb University in 1998. She then received her Ph.D. in geobiology from California Institute of Technology in 2004. Her Ph.D. research investigated the role of microbial processes in the formation of laminated limestone rocks that were common for the first eighty percent of Earth's history. That work won her the 2007 Subaru Outstanding Woman in Science Award, which is presented to a woman whose Ph.D. research has impacted the field of the geosciences in a major way. Dr. Bosak spent two years as a Microbial Sciences Initiative Fellow at Harvard University before she joined the faculty at MIT in 2007. where she is now Cecil and Ida Green Assistant Professor. Her
