Research Overview

Prof. Jessica Warren’s lab in the Department of Geological Sciences at the University of Delaware studies the geochemistry and rheology of the Earth’s mantle, using peridotites collected on land and at sea. Peridotite is the dominant lithology of the upper mantle, consisting of olivine, orthopyroxene and clinopyroxene, with minor amounts of spinel and sulfide. In the oceans, peridotites are collected by dredging, diving or drilling, while on land they are found as xenoliths and uplifted massifs. The Mantle Processes group uses peridotites to study mantle dynamics, deformation, and evolution by integrating geochemical, petrological, rheological, and structural methods. In particular, the group focuses on two themes: (i) constraining mantle composition and evolution and (ii) under- standing mantle flow and shear localization.

Research Opportunities
I am always looking for enthusiastic people to join my group! Contact me for more information.

  • Undergraduates: I often have projects available. I encourage you to contact with me to discuss options and timing. Both academic year and summer projects are possible and the earlier you contact me, the easier it is manage!
  • Graduate students: a position is available for Fall 2022.
  • Postdocs: I am always interested to hear from prospective postdocs with similar research interests. Position availability is dependent on funding, but I am happy to discuss possible projects and explore funding opportunities!
