Leigh Anne Riedman
I received my PhD from the University of California, Santa Barbara; my MS from University of California, Los Angeles and my B.S. in Geology from Louisiana Tech University. I joined Andy Knoll's Lab in August of 2015 as a NASA Astrobiology Postdoctoral Fellow.
I study the most interesting billion years of life's history- the Neoproterozoic and Mesoproterozoic Eras (~1600 to 540 million years ago). This is when eukaryotes (cells with nuclei) became more diverse and abundant and I want to understand more about how that happened and why it happened when it did. During this time there were also major changes in the chemistry of Earth's atmosphere and oceans and there were at least two global glaciations. With my research I am working to understand life's role in that changing world.
