Welcome to the webpage for Elizabeth Sibert! My research asks the question “How does the ocean, and marine life, work, in the past, present, and future?” I am broadly interested in the evolution, structure, and function of marine ecosystems, and how these ecosystems respond to global change. I use a multi-proxy approach to study how the ocean ecosystems have changed through time, with a focus on responses to climate and biotic events in Earth’s more recent history, such as global warming and mass extinctions. I specialize in using ichthyoliths, tiny fossil fish teeth and shark scales found in pelagic sediments worldwide, which I then incorporate with myriad other climate and biotic proxies to better understand the ecosystem as a whole.

I am currently an Assistant Scientist at Woods Hole Oceanographic Institution, where I am setting up the Paleo-Biological Oceanography laboratory. If you are interested in research opportunities, please reach out via email – I’d love to hear from you!

My previous positions include Associate Research Scientist (2022-2023) and Hutchinson Postdoctoral Fellow (2020-2022) at Yale University, and Junior Fellow in the Harvard Society of Fellows (2016-2020). I completed my PhD in Oceanography in 2016 at Scripps Institution of Oceanography.

In addition to my research, I am passionate about making science and research accessible to folks with disabilities (see Kingsbury et al 2020, JGE, and Cooke et al 2020, EOS). I have also been discovering the fun of 3D printing, mostly fossils and other teaching aids.

I’ve always loved the ocean, from the moment I first learned of the creatures that could live their lives underwater. What captured my imagination at first was the animals themselves, and as I dug deeper into their biology, I learned that life in the oceans was intricately linked to the physical, geological, and chemical properties of the ocean itself, and I am fascinated by how these links work together to create the ocean world that we see today.

Microfossil fish teeth and denticles are shown on a black background. They are arranged in 4 neat rows with approximately 9-12 fossils per row. There is a scale bar at the bottom showing that most of the teeth are between 400 and 800 microns in length and about 100-200 microns in width. The image was taken using a high resolution digital microscope, as these fossils are far too small to be seen without magnification. These fossils are approximately 50 million years in age, and are from the DSDP Site 596, a marine sediment core from the South Pacific ocean.
