Climate / Climate Change
Professor Klein is an expert in statistics, and her research has been successfully used in many interdisciplinary applications, including the fields of medicine, ecology, life sciences, and economics.
Her research interests cover those on Bayesian Computational Methods and Bayesian Deep Learning, which allow for uncertainty quantification and better interpretability in several model classes, but are also scalable to large data sets and highly-parameterized models.
Beyond that Prof. Klein also works in distributional regression models, which are particularly useful in analysing complete distributions of quantities of interest in the presence of complex associations with influential variables. These models also allow to model dynamics in space and time, thus relating her research to spatial statistics.
Furthermore, Prof. Klein works on general smoothing and shrinkage methods in the context of statistical and machine learning as well as on network analysis.

Prof. Ulrichs is an expert in the field of ecophysiology of plants with a special focus on plants in urban spaces. His team studies processes, which determine plant growth, e.g. stress exposure in an urban environment. The emphasis of his research lies on the analysis of the secondary metabolite balance (incl. its nutritional function), substance allocation, competition and plant-insect interaction. Prof. Ulrichs other major field of expertise is the quality assurance in food supply chains of horticultural products, especially for perishable foodstuffs like fruits and vegetables in temperate zones as well as in tropical/subtropical regions.

As part of their scientific activity Dr Markus Krutzik and the team members of the.quantum.chapter have acquired an extensive amount of expertise in developing tailored quantum sensors - from key technology to subsystem and system level. Quantum optical sensors and optical clocks are used in high-precision inertial navigation, gravimetry and gradiometry or for the synchronisation of networks. Hence, they are central for navigating GPS-free environments, for geophysics, the exploration of natural resources, the monitoring of climate change, and for addressing fundamental questions of modern physics. Central to their research are compact and robust setups for optical spectrocopy, absolute frequency references, and ultra-cold atom based inertial sensors. For this purpose, the team developed lasers and optical systems for generation and manipulation of light, as well as control software and data management platforms. Their setups are not only operated in laboratory research: They are also used as in field or even in space. In addition to development, testing and operation of atomic quantum sensors, Dr Krutzik and the team gained expert knowledge in all stages of mission and system design, ranging from mission architecture and identification of requirements to system integration and qualification, as well as development of control concepts and data analysis. In addition to Humboldt-Universität zu Berlin Dr Krutzik is also associated with Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik.

Prof. Hostert’s explores cutting-edge satellite data analysis. His main focus lies on questions regarding the global change, particularly large-scale mapping in agrarian- and forestry systems and near-nature ecological systems worldwide. He analyses the change of the earth’s surface through different methods, for example with machine learning, big data, time series analyses, hyperspectral and multisensor approaches, as well as multiscale analyses. Regional expertise of the team covers Germany, the mediterranean areas and South America, as well as Central Asia.

Dr Schwalbe and his group investigate the activation of small molecules at metal complexes. The main focus is not only research on electrocatalytic but also photocatalytic processes. With the help of renewable energy sources, and preferably the direct use of sunlight, formally unreactive molecules such as CO2, O2 or H2O should be transformed efficiently into valuable compounds. The syntheses of metal complexes is in fact in the foreground, but following the comprehensive chemical, structural and physical characterisation of the newly designed compounds their catalytic properties are especially explored. At the moment Dr Schwalbe is working in particular on the light-driven reduction of CO2 to CO or HCO2H, and in doing so he examines the influence of different reaction parameters (e.g. water content of the solvent, used photosensitizer or excitation wavelength) on the product selectivity. Furthermore the development of catalytic systems for homogeneous as well as heterogeneous water oxidation or oxygen reduction is pursued. For this, Dr Schwalbe considers on the one hand the fixation of molecular systems on electrode surfaces, and on the other hand the direct integration of monomeric building blocks in polymer networks. Within his research efforts he creates promising catalysts (and dyes) that can later be applied in e.g. fuel cells or photo-reactors.

The team of Christoph Schneider works on the impacts of climate and climate change in the field of urban climates and in the field of cryospheric sciences (anything related to snow and ice). His expertise comprises the downscaling of meteorological respectively climatological data for applications in high spatial resolution, for example for urban planning and construction schemes and also for the analysis of potential impacts of climate change on the level of city quarters and cities. Furthermore, such numerical and empirical-statistical procedures are applied to the projection of future water resources in glaciated catchments in high alpine environments worldwide. This also leads to applications regarding the future state of snow covers in mountain ranges which is especially important for questions of future prospects of snow sport tourism. In both fields of applications, the urban climatology and the cryospheric research, measurement strategies and data acquisition of relevant atmospheric variables for the projects are used besides theoretical modelling approaches and downscaling as outlined above.
