Rate My Professor Alexander Piotrowski

Employing radiogenic isotopes such as neodymium (Nd) and lead (Pb), along with proxies like 231Pa/230Th ratios, his group analyzes sediment cores from global sites including the Atlantic, Indian, and Pacific Oceans. Specific foci include South Atlantic deep water sourcing during glacial-interglacial transitions, glacial millennial-scale variability, North Atlantic circulation strength, and deglacial water mass changes. Key publications include 'Temporal relationships of carbon cycling and ocean circulation at glacial boundaries' (Science, 2005), 'Oscillating glacial northern and southern deep water formation from neodymium and carbon isotopes' (Earth and Planetary Science Letters, 2008), 'Synchronous deglacial overturning and water mass source changes' (Science, 2010), 'Reconstructing deglacial North and South Atlantic deep water source using foraminiferal Nd isotopes' (Earth and Planetary Science Letters, 2012), 'North Atlantic Deep Water Production during the Last Glacial Maximum' (Nature Communications, 2016), and 'North Atlantic ocean circulation and abrupt climate change during the last glaciation' (Science, 2016). In 2020, Dr. Alexander Piotrowski was appointed Reader in Palaeoclimatology and assigned to the Department of Earth Sciences. He leads a research group, supervises PhD students, and contributes to university bodies such as the Marr Memorial Fund awarders.
