Linda Kah is a leading expert on the evolution of the Earth during the Mesoproterozoic (1.6 to 1.0 billion years ago). Her research focuses on reconstructing oxygenation of the Earth's oceans and atmosphere and interpreting the effects on biological activity in the oceans. More recently, she has expanded her interest in ancient sedimentary environments to the surface of Mars, where she is investigating potential habitable environments as a co-investigator on the Mars Science Laboratory mission. In 2014, Kah was named a fellow of the Geological Society of America.
Topics of expertise: Mars, geochemistry, sedimentary geology, and earth evolution
