Frank studies the co-evolution of the Earth and its biosphere from a geobiologic perspective, searching for traces of life in deep (and not so deep) time—how has life affected the history of our planet, and how has the history of our planet affected the evolution of life? He is probably most noted for his studies of life during “Snowball Earth”, the most severe glaciation known that occurred ~700 million years ago, but other recent projects include the origin of animals, mass extinctions, and investigations into new biosignatures for use with ancient rocks on Earth and other locales in our solar system (e.g., Mars). Frank has studied rocks as old as 3.5 billion years and as young as those forming today, and field sites are located in the US, Canada, Mexico, Peru, Australia, Namibia, and China.
