Andrew Knoll, Ph.D., Fisher Professor of Natural History and Professor of Earth and Planetary Sciences), Harvard University.

Professor Knoll has been a leader in demonstrating the connection between Earth’s geological and biological history. Today, an understanding of this relationship is necessary for everyone concerned about the plight of our planet. Dr. Knoll discusses his new book and how the geological-biological partnership has evolved over 4 billion years. He also addresses the need to understand the difference between the natural changes over time and those caused by climate change brought on by humans.

Professor Knoll’s research focuses on the interconnections between Earth’s geological development and evolution. He also serves on the science team for NASA’s Mars Exploration Rover (MER) mission to Mars.

Andrew Knoll has received numerous awards for his work, including the International Prize for Biology. His 2003 book, Life on a Young Planet won the Phi Beta Kappa Book Award. He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, the American Philosophical Society, and the American Academy of Microbiology.
