Biography
In November and December of 2016 Dr. Gregg served as Chief Scientist of the OASIS Expedition. K-12 students had the opportunity to follow along with the OASIS Science Team on an expedition of discovery to investigate submarine volcanoes that have never been explored before. You can learn more about the 2016 expedition on the OASIS Facebook Page and/or OASIS YouTube Channel. Make sure to *Subscribe* to follow along with the team when they return to the OASIS field sight in December 2018!

Research Interests
Volcano Geophysics and Geodynamics, Mid-Ocean Ridge Processes, Melt Generation and Migration Through the Upper Mantle. My current research utilizes thermomechanical models to better understand the rheological controls on magma reservoir growth, pressurization, and volcanic eruption. I also use geodynamic models to investigate melting and melt migration in the mantle beneath mid-ocean ridges. My work involves a multi-pronged approach that combines data collection on land and at sea with data analysis and model development. Future projects include case studies of active continental volcanic systems as well as seagoing field expeditions to better understand the formation of new oceanic crust at mid-ocean ridges.
