Jackson's research explores the depths of Earth's underworld: From the central inner core to plume-roots at the core-mantle boundary to deep plumbing architecture underneath active volcanic systems:

*New Results Reveal Surprising Behavior of Minerals Deep in the Earth
(Highlight) (Cordier et al., Nature 2023) (more details)

*The magmatic web beneath Hawai‘i
(Highlight) (Wilding et al., Science 2022)(Movie)

*Single-grain analysis of iron's oxidation state in volcanic amphiboles (Ratchbacher et al. 2023)

*New results on dense hydrous phases: vibrational anisotropy , equation of state of oxyhydroxides and high-pressure phase transitions in hydrous sulfates, with implications for deep hydrogen cycling on Earth and beyond

*Iron-rich (Mg,Fe)O at the CMB: Highly anisotropic with very low wave speeds and viscosity!
