معرفی
Matthew G. Jackson is a Professor in the Department of Earth Science at UC Santa Barbara. His research focuses on the long-term geochemical evolution of the Earth, particularly the connections between the Earth's surface and deep mantle. He investigates how subducted oceanic lithosphere is recycled back into the mantle and sampled at oceanic hotspots. Jackson leads a lab exploring the origins of mantle heterogeneity, with a focus on isotopic tracers (e.g., Sr, Nd, He, W) and their implications for mantle dynamics. His work bridges geochemistry with seismology and geodynamics, aiming to constrain the mantle's compositional structure.

Research interests include the fate of subducted materials, early Earth evolution, and the geochemical signatures of recycled crust in hotspot lavas. Jackson collaborates widely, integrating data from fieldwork, geochemical analyses, and computational modeling. His lab has identified ancient geochemical reservoirs in mantle plumes, such as the Samoan and Icelandic plumes, linking them to the Earth's earliest crustal processes.
Key projects include studying the Samoan plume's interaction with the Tonga trench, the geochemical structure of mantle plumes using machine learning, and the role of recycled sediments in mantle heterogeneity. His work has been featured in Nature, Science, and PNAS, with over 150 publications. Jackson advises graduate students and collaborates internationally, contributing to expeditions like the NOAA Okeanos Explorer mission to American Samoa.
Grants include NSF funding totaling over $8 million, supporting research on mantle plumes, subduction zones, and isotopic tracers. His outreach includes educational initiatives in Samoa and the Cook Islands, engaging local communities in volcanic and geochemical studies.
