Research
Brief Description
The Meert group is focused on the how and when continents (and supercontinents) assemble and break apart. These processes have operated since at least the Paleoproterozoic and have a profound influence on oceanic circulation (and therefore climate), the evolution and extinction of major life forms and feedback to deep earth during their life cycle. Because we use the Earth's magnetic field to study these past events, my group also studies the evolution of the Earth's magnetic field. Our work is primarily focused on the Precambrian (4.5-0.541 Ga), but we do not limit our curiosity to that interval of time. See my home page for recent news articles about our research.

Ongoing Projects
EAR18-0693 (8/31/18) National Science Foundation (Tectonics): Incredible India:High Resolution Proterozoic Paleogeography through integrated studies of mafic dykes (to 2/28/2021)
This project is aimed at sampling mafic dykes in the Singhbhum, Bundelkhand and Dharwar cratons with two goals; (1) Assess the timing of unification between the southern Indian cratons (Dharwar, Singhbhum and Bastar) and the northern Indian cratons (Bundelkhand and Aravalli) and (2) Integrating the paleomagnetic data in a global framework.
Interested in Graduate Work? Please contact me via e-mail. I am looking for a Ph.D. and/or MS student to work on these projects.
