Maureen Raymo, Ph.D., is a Research Professor at Boston University and adjunct scientist at Woods Hole Oceanographic Institution. She studies links between physical and chemical processes operating within Earth's climate system.

Raymo studies causes of climate change over Earth's history, in particular the role played by the global carbon cycle and Earth's orbital variations around the Sun. She uses stable isotopes of oxygen and carbon to study past ocean circulation and ice volume history. Raymo recently has proposed that changes in the gradient in isolation received between low and high latitudes controlled global ice volume in the late Pliocene and early Pleistocene. Raymo has proposed also that cooling of global climate over the last 40 million years was caused primarily by enhanced chemical weathering and by consumption of atmospheric carbon dioxide in mountainous regions of the world, particularly in the Himalayas. Most of her work is based on data collected from deep-sea microfossils recovered using research vessel capabilities.

Raymo received Sc.B. degree from Brown University and M.A., M.Phil., and Ph.D. degrees from Columbia University.
