Biography

I have studied physics at Heidelberg University and greatly enjoyed the work as student representative at the time. During my Diploma project and subsequent PhD I have explored natural radionuclides (Thorium, Protactinum, and Uranium Isotopes) in deep sea ferro-manganese crusts and nodules, hemipelagic sediments, secondary carbonates such as travertine, speleothems, and corals. I worked out a new and very simple analytical method to extract and purify Pa from such archives (Frank et al. NIMB 1995), which allowed for cross dating using the 230Thxs and 231Paxs methods. It turned out that 231Pa behaves in the ocean more complex than generally assumed, which I tought must be a state change of Pa - oxygenation, but this claim was never accepted by the scientific community and remains unproven. Thus, I move to the precise dating of dirty carbonates and had the chance to be at the start of a far reaching new research field that has been growing ever since thanks to steady technological advances in mass spectrometry.

Asked for the most important finding, I suppose it was the discovery of the age of a carbonate crust underneath the city of Troy that appearently dated back into times described by Homer in the Illias (Frank et al. Archeometry 2002). The second most important finding was the dating of deep-sea corals and the possibility to extract the radiocarbon age of water, which was published in Nature (Mangini et al. Nature 1998). Another aspect of this start into a research career was the realization that team work is most important, as are international contacts, curiosity and the wish to help students into science. By the end of my PhD I had supervised a large number of student projects, wrote scientific proposals, organized the first national 231Pa workshop in Heidelberg, and was with two fellow doctoral students (Andreas Bollhöfer and Christopher Strobl) creating a social life of the team including a field trip to the nearby Karst regions. Note, my PhD was a project between two research groups, the one of Prof. Augusto Mangini (Heidelberg Academy of Science) who I acknowledge as my most important scientific mentor. Prof. Günther Wagner from the Max Plack Institute of Nuclear Physics was the second mentor who lifted the curtin about Archeometry and Archeology and as such he was a mentor who allowed me to meet Prof. Manfred Korfmann, who at the time was leading the excavations at Troy. This way I had the chance to evolve in two distant research fields at the same time, which I kept ever since.

Through the past two decades, my work was centerd on these distant fields, the processes driving metal transport in the ocean over climate time scales and the high precision dating of secondary carbonates in general and in cases of archeological sites of early humans in Europe. During my research training I was lucky enough to receive a prestigeous DFG postdoctoral fellowship to conduct research at Lamont Doherty Earth Observatory at Columbia University (New York), where I was working with Prof. Steven Goldstein and Prof. Sidney Hemming. Two Giants in science, which have revealed to me a very different strategy to approach scientific questions than I had learned at Heidelberg Univsersity. During my time at Lamont I had the chance to meet many postdoctoral fellows, who later on became famous for their discoveries (Prof. Jess Adkins, Prof. Gideon Henderson, Prof. Randye Rutberg, Prof. Pierre Friedlingstein, Prof. Marina Levy, Prof. Alex Piotrowski, and many others). Subsequently I came back to Heidelberg University but this time to the Earth Science Department.

Back than, I initiated the use of continental secondary carbonates for climate science in Heidelberg, which was funded by the DFG and led ultimately to envision the DFG research group DAPHNE. In 2000 I obtained the opportunity to lead the Neodymium isotope sampling during my first research cruise to the South Atlantic on board RV Meteor. An unforgettable cruise in partly more than 10 m high swell. Instead of further proceeding in the Marine Science directions I obtained a second prestigeous postdoctoral fellowship, an individual Marie Curie fellowship, and moved to Paris, where certainly the most important evolution of my career took place.

The former director Dr. Laurent Turpin selected me for a permanent staff scientist position at the Laboratory of Climate and Environmental Science (LSCE) at the french CEA and CNRS (Gif-sur-Yvette/Saclay). During the following 12 years in France I achieved a new analytical infra-structure for isotope geochemistry, including the multi-collector inductively coupled plasma source mass spectrometer and ultra-clean laboratories. I had the chance as team leader to develop the research team in new science directions, and obtained funding for the exploration of cold-water corals as a novel climate archive, including the first cruise, which I led as chief scientist to Iceland. My colleagues at LSCE where a source of great enthusiasm and excitment, but also culture, politics and food. Many new ideas came to light and climate modelling became a visible part of the science work. It is impossible to mention all the important influencing people along the way, but Dr. Martine Paterne helped shape my vision of science and supported all my actions, Prof. Matthieu Roy-Barman who sadly passed away much to early wrote the book I always wanted to write (Marine Geochemistry) and I will for ever miss the discussions about radionuclides in the ocean and mass spectrometry. Prof. Christoph Colin showed me that teaching is hard work but very rewarding, and that radiogenic isotopes are most important tools not only in Paleoceanography.

Dr. Christine Hatté was the first person I met who successfully combined modelling and experimental work on the modern and past carbon cycle (in soils) and made me work out the idea that cold-water corals in the eastern Atlantic ocean in dependence of climate (Frank et al. Geology 2011).  The reward of all this work was the career of many of the students I had supervised along the way, the funded projects, the French language and culture and ultimaltely my habilitation in 2010 at the University Versailles St. Quentin as well as the nomination as Senior Expert of the CEA. Ultimaltely the CEA special award for the new infra-structure. Finally, I must also thank Dr. Martine Paterne for selecting me in first place and for her rigor in science, to which I will never stand. Dr. Guy Cabioch from IRD Paris, who also passed away much to early kept my eyes watching for the tropical corals as climate archives and it took me more than 10 years after his death to come back to the subject I wanted to persue with him.

In 2012 I than accepted the position of Professor in Physics and Earth Sciences at Heidelberg University. I became director of the Institute of Environmental Physics. Since than, the team has developed a broad research program from past climate reconstructions using climate archives to the detection and quantification of atmospheric water transport and greenhouse gases. Again a large analytical infra-structure was built. Two research cruises, one to the Mid-latitude North Atlantic seamounts and the one to the Mediterranean Sea were conducted and new research cooperations led to the study of speleothems around the world. Many colleagues supported my work here too.

I contribute widely to the teaching in Physics and Earth Science and I was honored by the teaching award of the Faculty of Physics in 2018. I have supervised, mentored, supported, and examined a large number of students at all stages of their career including the one time participation to a mentoring program of the Leibniz Society. I act as reviewer for numerous journals and funding bodies, and I am associate member of the editorial board of the recently founded journal EGU Geochronology. I am an active member in the Geochemical Society, AGU, and DPG. My career has been and still is driven by the people and in particular the studnets I have the chance to get to know and work with, it is the sum of endless influences.

To close I cite Albert Einstein (a citation found on internet): I don't teach my students, I provide the circumstances in which they can learn.

Research interests

  • The physics of (past)climates and the geochemical cylces of elements (in particular within the ocean) are my main research instrests. I appraoch the field via the study of natural archives such as corals and speleothems, but also marine sediments. Those can be accurately dated using natural radioactive nuclides and furthermore store information on past climate dynamics, climate state variables and elemental cycles, including the carbon cycle. However, I am also interested in archeometry, the link between climate and human societies and technological developments of mass spectrometry.
