Current areas of active research include: landscape evolution in response to tectonics, changes in climate and sea level; development of density models for the mantle by integrating seismic tomography and mantle convection modeling; melt generation and extraction during continental rifting; carbon cycle of the Hadean-Archean Earth; and surface deformation in response to flat-slab subduction. Inherent to my research is high-performance computing and the development and continuous improvement of geodynamic and landscape evolution software.

Dr. Junium is a sedimentary and organic geochemist with a focus on the redox evolution of the Earth, specializing in biogeochemical cycling. His research interests span the spectrum of geologic time from the Archean to modern systems. Currently, he is am working principally on the Cretaceous and Neoproterozoic with an eye toward understanding future global change.
