Joseph Stewart is a lecturer at the University of Bristol, specializing in Earth Sciences. His research focuses on geochemistry, paleoceanography, and biomineralization, particularly using marine archives to analyze and record past environmental changes. Stewart employs cold-water corals, stylasterid corals, and foraminifera as natural archives to reconstruct ocean circulation, climate variability, and seawater chemistry over various timeframes, including the Holocene, deglaciation periods, and the Cenozoic era. He is actively involved in developing and refining geochemical proxies, such as boron isotopes and various elemental ratios, to calibrate environmental parameters like pH and temperature. His work includes both laboratory and field studies aimed at improving the reliability of these proxies and understanding vital effects associated with biomineralization. Stewart is also interested in the biological controls of coral calcification under varying oceanic conditions and the broader implications of ocean acidification and climate change. His contributions highlight the importance of geochemical records in understanding Earth's climatic feedback mechanisms.
Department of Physics research themes include Astrophysics, Materials and Devices, Particle Physics, and Quantum and Soft Matter.
