Education

Ruth Blake completed a B.S. degree in geology from Wayne State University and a M.S degree in hydrogeology from the University of Texas. She earned a Ph.D. in geochemistry from University of Michigan in 1998.[2] Blake's doctoral research focused on how microbial activity can affect oxygen isotopes in phosphates.[3]

Career and research

While a professor at Yale, Blake expanded on her graduate research focus using isotopic evidence in ancient marine phosphates to show that there was significant biological activity in the ocean during the Archean era.[4]

Blake has worked on numerous other research topics related to biological and/or chemical activity in oceans, sediments, and soils.[5][6] She has worked on methods development in isotope geochemistry.[7]

Awards and honors

Blake was the 2002 winner of the F.W. Clarke Medal from the Geochemical Society.[8]
