Research Interests:

How Earth works, from core to crust. My areas of expertise are palaeomagnetism, cyclostratigraphy, and Earth history. The Earth system is completely integrated, but plate tectonic theory is not. Explaining the dynamics of past supercontinents, and even predicting future supercontinents, requires a systems theory approach.


Papers make careers. Please contact me if you (i) have a paper idea or (ii) wish to help me finalize one.
