Matthew Osman

Matthew Osman is an Assistant Professor of Climate Science in the Department of Geography at the University of Cambridge. He leads the Cambridge Computational Climate and PaleOceanography (C3PO) group and serves as a supervisor for the Cambridge NERC Doctoral Landscape Awards (DLA).

Dr. Osman's research focuses on understanding climate dynamics across various timescales by integrating geochemical proxy records, modern observations, and climate model simulations. His work centers on:

• Developing quantitative tools to reconstruct past climates and constrain future projections
• Using data assimilation and modeling methods for key climate intervals (mid-Pliocene, Last Ice Age, interglacials)
• Creating probabilistic frameworks combining proxies with climate simulations
• Developing statistical proxy system models for ice cores and marine records
• Investigating cryosphere-climate feedbacks, particularly ice sheets and sea ice

His research spans sub-seasonal to millennial time intervals, specializing in bridging climate proxies with global climate models. He works closely with the international PMIP/CMIP community on projects spanning Arctic sea ice sensitivity, AMOC weakening, and carbon cycle feedbacks.

Dr. Osman actively supervises PhD students through the Department of Geography PhD Program and encourages students interested in quantitative climate science to develop projects in:

• Using paleo data to constrain future climate projections
• Developing fingerprinting techniques for proxy records
• Building probabilistic proxy system models
• Applying paleoclimate data assimilation during ice sheet collapse
• Climate risk modeling using physics-informed statistics

The C3PO group maintains a strong commitment to diversity and inclusion, welcoming researchers from all backgrounds to address the climate crisis through quantitative, multidisciplinary approaches.
