Matthew G. Braun

Matthew G. Braun studies ancient Earth history using chemical signatures preserved in rock layers, a method called chemostratigraphy, to reconstruct past environmental and climate changes. His work focuses on the Silurian and Mississippian (Carboniferous) periods, roughly 300-440 million years ago, using carbon isotope patterns to date rock layers precisely and investigate global cooling and ocean chemistry events. This research helps build detailed timelines of ancient climate shifts and biological turning points recorded in sedimentary rock sequences from sites like Anticosti Island (Canada) and the Burlington shelf (United States).

Publication output was sparse and irregular in the earlier part of the decade but has become more frequent and steady since 2021.
