Research highlights

To date, I principally work in 3 areas of active research:

• The permeability of random heterogeneous materials, with specific applications to volcanic and other crustal rocks. 
• The coalescence of large heterogeneous arrays of viscous liquid droplets under surface tension, applied pressures, and chemical disequilibrium conditions.
• The viscoelastic response of multiphase magmas to stress, including cycles of material rupture and healing.

I additionally have contributed to work involving bubble growth and bubble deformation during flow of magmas, the formation of obsidian, the motives and methods of producing vitrified forts in European antiquity, and the evolution of language use in modern poets, among other topics.
