I have two main areas of research that pursue Earth history and its Solar System context:
Paleomagnetism applied to the study of supercontinent assembly and dispersal, the Precambrian-Paleozoic transition, terrane tectonics and orogeny
Mineralogy and petrophysical properties of Earth & planetary materials as it relates to exploration, meteoritics, and the evolution of the Earth and small bodies of the Solar System
These are currently pursued by my research group along the following themes:
Paleogeography of the Earth: determining the Earth’s Precambrian-Paleozoic paleogeography via paleomagnetic and other techniques, as a context for understanding extreme paleoclimates, burgeoning life, and as a tracer of global geodynamics.
Tectonics of accretionary orogens and mountain belts: paleomagnetic tracking of the collision, obduction and lateral motion of crustal fragments –terranes– to investigate the mechanisms of their assembly into mountain belts (Applalachians-Caledonides, Canadian Cordillera, Central Asia).
Shock metamorphism and parent body processes in the Early Solar System: investigation of the mineralogy and petrology of meteorites as recorders of impact shock deformation, redox processes and small body evolution
Petrophysical properties, mineralogy and mineral exploration: investigation of mineralogy, density, porosity, magnetic, electrical and acoustic properties of ore deposits and their host rocks, as a guide for mineral exploration
