Thanks for stopping by! My name is Courtney and I am a Peter Buck Postdoctoral Fellow at the Smithsonian National Museum of Natural History.

As a biogeomagnetist, I combine aspects of biology, geology, and magnetism. I take what we know about living organisms and use that information to learn more about the past and, similarly, I take what we know about the past and apply that to the present. I do this by using techniques in rock and environmental magnetism to characterize magnetic minerals that record this information. I am most interested in what the information stored in magnetic minerals can tell us about how ocean chemistry changed over past warming events analogous to modern climate change.

My favorite magnetic minerals that I study are super tiny (each ~1/1000 the width of your hair!) and were made by oxygen-sensitive microbes. Using these “fossil magnets,” we can better understand ocean chemistry in the past, present, and future. When I am not playing with magnets you can find me hiking with my dog, backpacking, painting, playing soccer, skiing, or doing some yoga.
