Sedimentology, Stable Isotope Geochemistry, Carbon Cycle, Marine Geology, Paleoclimatology and Paleoceanography

I am currently working on deep marine sediments to understand what impact climate changes (especially through Eocene) had on ocean floor sedimentation. My other interest is to tie up these deep ocean sedimentary dynamics with changes in deposition pattern in shallow marine setting in times of extreme warmth, like PETM and early Eocene Hyperthermals.

volcanism, Hawaii, two-phase flow, bubbles, solubility, numerical modeling, deformation

My thesis focused on how magma is transported from depth to the surface at Kilauea Volcano, Hawaii. A great natural laboratory for this is Hawaii, where a long-lived eruption is ongoing (1983-present).

geochemistry

Janne is an isotope geochemisty interested in planetary differentiation, the origin and evolution of continents, and cosmochemistry.

Magmatism-tectonism-climate interaction, evolutions of continents

I am interested in the structures and evolutions of continental arcs and how the geological processes (e.g. magmatism, tectonism, erosion) contribute to the formation of continents and their impacts on global climate.
