Dr. Ryan H. Glaubke

Hi, there!

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

For a decade, I have studied the ocean’s role in shaping past, present, and projected climate change. My work centers on reconstructing climate change before the instrumental era through the geochemistry of microfossils preserved in seafloor sediments. These sediments—layered over millennia like pages in a history book—offer valuable insights into Earth’s climate system and inform how we understand its future. This site showcases my contributions to that work.
