Professor Alexander Piotrowski works in the Department of Earth Sciences at the University of Cambridge, specializing in Palaeoclimatology and Climate Change, specifically focusing on the Earth-Ocean-Atmosphere systems. His research is centered around understanding the connections between ocean circulation and climate change throughout recent Earth history. His investigations into global ocean overturning and deep ocean processes aim to uncover the role of large carbon dioxide reservoirs in regulating atmospheric exchanges on short timescales. He employs radiogenic isotopes and geochemical tools across various globally distributed sites to reconstruct historical ocean geochemistry. Notable studies include examining changes in South Atlantic deep water sourcing during glacial-interglacial transitions and investigating the links between past North Atlantic deep water changes and palaeoclimate alterations. His group utilizes neodymium isotopes to explore these dynamics, contributing to a broader understanding of the global thermohaline circulation changes over glacial cycles. Piotrowski has supervised numerous research projects focused on deep ocean isotopic reconstructions and sediment sourcing in diverse oceanic contexts.
