Our Distinguished Lecturers

Karen Fischer:
The Subduction Factory

In her research, Karen Fischer uses seismological methods to understand the structure and dynamics of the Earth's crust and mantle. Her work focuses on mantle flow and melting processes in subduction zones and on the on the continental lithosphere - its properties, evolution and interactions with the deeper mantle. Recent field projects include an array of broadband seismometers in Nicaragua and Costa Rica (the TUCAN Experiment) whose goal is to image the subducting slab and mantle wedge and clarify their relationships to the generation of arc magmas.

Karen is a Professor of Geological Sciences and a Royce Family Professor of Teaching Excellence at Brown University.

    Daniel Lizarralde :
    Rupturing Continental Lithosphere

    The evolution of Earth's lithosphere, particularly at continental margins, is Daniel Lizarralde's primary research interest. He uses active-source seismology to image crustal and upper-mantle structure and make inferences about tectonic and magmatic processes. He has studied rifting processes that formed the U.S. East Coast margin and the Gulf of California, and he also studies processes at convergent margins with work in the Aleutians and in Costa Rica.  Other margins-related processes Dan is working on include submarine groundwater discharge and methane gas-hydrate formation.

    Dan is an Associate Scientist in the Department of Geology and Geophysics at the Woods Hole Oceanographic Institution.

    • Casey Moore :
    The Seismogenic Zone

    Casey Moore's scientific work involves the linkage of structural geology and fluid flow in rock evolution. Currently he is studying processes of earthquake generation along faults, especially what makes some faults seismogenic and others not. He is also interested in how the earthquake processes are expressed and sequenced in the structural evolution of accretionary prisms. Casey Moore has studied both modern submarine subduction processes and ancient exhumed equivalents in California, Alaska, Japan, southern Mexico, and the Caribbean.

    Casey is a Professor of Earth and Planetary Sciences at the University of California, Santa Cruz. He was previously a Distinguished Lecturer for the Joint Oceanographic Institutions/United States Science Advisory Committee.

    • Charles Nittrouer:
    Source to Sink

    Chuck Nittrouer has investigated continental-margin sedimentation in many settings around the world, where significant amounts of sediment are being supplied from rivers and glaciers. His focus has been on the processes related to sediment accumulation on time scales of decades, and has used a diverse range of tools (especially short-lived radioisotopes) to quantify the mechanisms of strata formation. Much of his research has involved collaborations with scientists is associated disciplines, in order to expand the relevance of the results.

    Chuck is a Professor in the School of Oceanography and in the Department of Earth and Space Sciences at the University of Washington. He teaches students from undergraduate to graduate levels.
