B.A., 1998, Geosciences, magna cum laude, Franklin and Marshall College

Area(s) of Expertise

Carbonate Biogeochemistry, Biomineralization, Ocean Acidification, Paleoceanography

Research Interests

Professor Ries’ research program investigates a wide range of subjects in the marine and geological sciences, including global climate change, paleoceanography, paleobiology, carbonate sedimentology, sulfur isotope geochemistry, biomineralization, and carbon sequestration.  The common thread throughout Prof. Ries’ work is oceanic change, which he investigates over broad temporal scales.  By combining field studies with complementary laboratory experiments, Prof. Ries is able to directly explore the biogeochemical processes that have changed the state of our oceans throughout the geologic past, as well as those that will drive critical changes in the immediate future.

A slightly more acidic ocean may help coral species

New research from Marine and Environmental Sciences professor Justin Ries explains how moderate increases in ocean acidification and temperature can enhance the growth rates of some reef-forming corals.
