Now entering its 19th year, the International Geobiology Course is an intensive, multidisciplinary summer course exploring the coevolution of the Earth and it’s biosphere, with an emphasis on how microbial processes affect the environment and leave imprints on the roc4 record. Participants get hands-on experience in cutting-edge geobiological techniques, learn from a broad team of eminent scientists in the field, and work in research groups to solve relevant questions. Applications are due by February 7, 2022.
