|Jake Jordan (PhD Candidate GEO) [RG]
A.B. Geophysics, University of Chicago (2011)
Jake studies the partial melting of the Earth (and other rocky planets). The partial melting of planetary interiors can lead to the onset of plate tectonics, volcanism, the chemical differences observed in rocks throughout worlds and may play an integral role in the evolution of habitable planets. Oh…and he spends his nights and weekends pretending to be an artist.
