geologist. She is a research professor at the University of Boston. She has won various prizes for her scientific work. In 2002, she was included by the illustrated magazine Discover in a list of the 50 most important women in science.^[1][2] Raymo earned her reputation particularly from developing (along with William Ruddiman and Philip Froelich) the uplift-weathering hypothesis. According to this hypothesis, tectonic uplift of areas such as the Tibetan plateau has contributed to surface cooling. During phases of mountain range formation, there are at the surface many minerals which can chemically interact with carbon dioxide. During the process of chemical weathering, there is a net removal of CO₂ from the atmosphere, as a result of which the temperature on the ground decreases. She and her co-workers suggested that measuring the proportions of isotopes of strontium in deep ocean sediments could substantiate the uplift-weathering hypothesis, but there are controversial ambiguities. She has also done important stratigraphic and paleoclimatologic work by means of oxygen isotope analysis of foraminifera from sample cores of deep ocean sediments.
