Research Interests: Broadly speaking, I am interested in the paleogeography of the Proterozoic Eon and how paleogeography influences climate, the biosphere and the tectosphere.   My research team uses a toolbox aimed at learning where (paleomagnetism) a particular piece of the Earth's crust was located and when (geochronology) it occupied that space.  By obtaining coeval paleomagnetic data from multiple cratons, we can establish past paleogeographic maps.  During the Proterozoic, at least two supercontinents are thought to have formed.  The first is named Columbia (also Nuna) and the second younger supercontinent is called Rodinia.  We are also interested in the origin, structure and evolution of the Earth's magnetic field.  Our other research focus is aimed at tools/techniques/strategies to recruit and expand opportunities in the Geosciences to under-represented groups.  I insist that all my students have a field experience as part of their degree.

Interested in Graduate Work?: Please contact me jmeert at ufl.edu.  We are looking for new students in Fall 2020.

Laboratory Facilities: We host modern paleomagnetic and geochronology laboratories housed in Williamson Hall.  There are also a suite of preparatory labs.
