- Temporal and spatial evolution of intraplate volcanism: ocean island and seamount volcanoes and aseismic volcanic ridges (Canary, Iceland, Madeira, Selvagen, Cape Verde, Hawaiian, Tristan/Gough and Galapagos Islands and associated seamounts and ridges; Marie Byrd, submarine Zealandia, Discovery, Agulhas Fracture Zone and Christmas Island Seamounts; Madeira/Torre Rise and Cocos, Carnegie, Malpelo, Coiba and Walvis Ridges), continental intraplate volcanism (Europe, New Zealand and western U.S.) and oceanic plateaus or Large Igneous Provinces = LIPs (Caribbean, Ontong Java, Manihiki, Hikurangi, Shatsky, Etendeka).
- Subduction zone magmatism, including arc initiation, temporal and spatial evolution of arc volcanism and volatile cycles through subduction zones (Kamchatka, Aleutians, Central America from Panama to Guatemala, Chile, Argentina, Tonga-Kermadec Arc, Iran, westernmost Mediterranean including southern Spain and northern Morocco, Izu-Bonin)
- Hazards related to intraplate and subduction zone volcanism (e.g. Etna, Stromboli, Iceland, Canary Islands, Central America, Chile, Kamchatka, Aleutians)
- Mid-ocean Ridge Volcanism and Plume-Ridge Interaction (Iceland, Galapagos Spreading Center, East Pacific Rise, Southern Mid-Atlantic Ridge, Woodlark)
- Evolution and Origin of Ocean Crust (Early Cenozoic to Mesozoic crust in the NW Pacific, eastern North Atlantic, NE Indian Ocean and accreted to North Island New Zealand; young crust outboard Central America, including Site 1256 first location where in situ gabbros were drilled)

I have taught a wide array of courses in both English and German at Columbia University in N.Y.C. (Paleontology Laboratory), University of California Santa Barbara (Oceanography Laboratory, Rock Identification, Summer Field Mapping Courses, Introduction to Geology), University of California Santa Cruz (Seminars on Isotope Geochemistry), and Kiel University (Introduction to Geochemistry, Magmatic Processes and Plate Tectonics, Geochronology and Isotope Geochemistry, Introduction to the Geochemistry of Igneous Rocks, Origin and Evolution of the Solar System, laboratory course on Radiogenic Isotope Analyses, geologic mapping courses, and seminars covering a wide array of topics including natural hazards, relationship between volcanism and climate, igneous petrology, geochemistry, application of geophysical techniques to understanding magmatic systems, and geodynamics).
Diversity and Gender
As my record shows, both diversity and gender balance are important to me. I believe all people, regardless of race, gender, religion, age, financial status or handicaps, should be treated equally, have the right to an advanced education, and to participate in basic and applied research. My Masters/PhD students and postdocs have come from 11 different countries (Germany, USA, China, France, Poland, New Zealand, Denmark, Russia, Switzerland, Spain, India and Iran). In addition, I have hosted visiting scientists from NZ, Costa Rica, Morocco, USA, Australia and Iran. Of my Masters and PhD students (who have received their degrees) and postdocs, approximately half (29 of 59) have been women. The Collaborative Research Center, during the six years I led it, had research going on throughout Central America (Panama, Costa Rica, Nicaragua, Honduras, El Salvador and Guatemala) and in Chile and Argentina. We forged tight relationships with our Latin America partners, which included hosting a Latin America Colloquium at Kiel University and a joint German-US-Central American meeting in Costa Rica. As Deputy Director and Scientific Program Speaker, I fought to increase both the diversity and the number of women at GEOMAR. These were important areas under review during the evaluation of the institute and the program, which received excellent to outstanding ratings. As a result of doing fieldwork with colleagues or spending time together on ship cruises, one gains intimate insights into different countries, peoples and cultures. This is one of the highlights of being a geologist for me.
