I have been working at the HZG - formerly the GKSS Research Centre- since 1996, where presently I am a senior scientist at its Institute for Coastal Research. My activities are also part of the research cluster CLISAP. My reseach areas are currently:

  • Analysis and simulation of the climate of the past millennia.
  • Climate and Sea-level variations in the Baltic Sea in the recent past and in the future.
  • Estimation of regional climate change with regional climate models and statistical downscaling methods.
  • Statistical analysis and interpretation of limnological time-series.

Previously, I lead the Department of Paleoclimate at the GKSS Research Centre. Here is a summary of my past positions:

Editorial board of Wiley Interdisciplinary Reviews Climate Change

Editorial board of Climate of the Past.

Editorial board Journal Climate Research.

Member of Working Group Euro-Med2K of Past Global Changes

"The present climate is unusual". Probably each of us has said or thought this sentence in recent times. But what does the word "unusual" mean? Have present warm conditions already occurred 100, 500, 1000 years ago? Are storms now more frequent and more intense than,say, 300 years ago, where European climate was undergoing one of the most coolest phases of the past few millennia? Were the recent warm temperatures "normal" in the past warm centuries, around 1000 years ago? We try to answer these questions by simulating past climates with comprehensive climate models. These simulations, together with the analysis of biological and geological climate archives, can provide usuful information about past climate conditions and extreme climate events and about how and why they varied.

Past positions

1994-1995. Laboratoire d'Oceanographie Dynamique et de Climatologie, Paris: Climatological observations seem to indicate that at middle and high latitudes there exist climate oscillations with periods of several decades. The origin of these oscillations may lie in the internal dynamics of the climate sytem, especially in the coupled interacion between the atmosphere and the ocean. However, the available observations do not allow for a clear identification of the physical mechanism that may give rise to those oscillations. The analysis of long-integrations of coupled atmosphere-ocean models may give clues about the real mechanism that are operating in nature. Since the amount of data generated in this integration is enormous, sophisticated statistical techniques to identify oscillations such data sets have been used, such as Singular Spectrum Analysis and Principal Oscillation Patterns.

1989-1993, Max-Planck-Institut für Meteorologie, Hamburg: Possible climate change is currently estimated with numerical models that simulate the present and the future earth climate. Their skillful resolution is nowadays of the order 2000 Km and therefore they cannot properly the local and regional features that are important to study the impact of climate change on the environment. One way to overcome this scale mismatch is statistical downscaling techniques: A statistical transfer function is estimated by analyzing observations of the large-scale circulation and the regional climate. This transfer function can be used to translate the changes of the atmospheric circulation simulated by a climate model to changes of the regional climate. The transfer functions may be designed by means of multivariate linear thecniques, such as canonical correlation, or by nonlinear techniques, such as analogue methods, classification methods or neural networks.

1984-1988, University of Zaragoza, Spain. Ph.D. Thesis: Ionic crystals are normally transparent to visible light. However the presence of metallic impurities or lattice point defects may change the optical properties of these crystals by inducing absortion and emission bands in the visible and infrared spectrum. These crytals may then be used, for instance, as active laser materials. Since the optical and magnetic properties of these impurities and point defects are very sensitive to their microscopic environment, these properties can also provide valuable information of their local crystaline structure and about structural phase transitions in the host lattice. With magnetic resonance techniques it is possible to estimate with high accuracy the bonding angles of the impurity and its neighbouring ions. Sometimes the distances between them can also be estimated, thus providing a full three-dimensional picture of the distorted lattice sourrounding the impurity.
