Dr. Ryan H. Glaubke

Hi, there!

My name is Ryan. I'm a postdoctoral research associate in the Paleo² Laboratory at the University of Arizona.

For nearly a decade, I have dedicated myself to understanding the ocean's role in past, present, and projected global climate change. My specialty lies in reconstructing climate change prior to the instrumental era using the geochemistry of microfossils buried in mud on the seafloor. Like pages in a history book, these layers of sediment contain important lessons from Earth's past that inform our projections of the future. Navigate this site to see my own contributions to this endeavor!
