Applications of Bayesian networks in natural hazard assessments
… from a modeling perspective many natural hazards share similar properties and challenges. Their complex nature as well as lacking knowledge about their driving forces and potential effects make their analysis demanding: uncertainty about the modeling framework, inaccurate or incomplete …

Time-dependent occurrence rates of large earthquakes in the Dead Sea fault zone and applications to probabilistic seismic hazard assessments
Die relativ hohe seismische Aktivität der Tote-Meer-Störungszone (Dead Sea Fault Zone - DSFZ) ist mit einem hohen Gefahrenpotential verbunden, welches zu einem erheblichen Erdbebenrisiko für die Ballungszentren in den Ländern Syrien, Libanon, Palästina, Jordanien und Israel führt. Eine Vielzahl …

Towards an understanding of synthetic glucocorticoid hazards in aquatic systems.
… methods. I conducted probabilistic environmental hazard assessments by employing environmental exposure distributions to estimate the probability of exceeding various hazard values. I observed synthetic glucocorticoids to be ubiquitous in freshwater systems, identified discrepancies among methods …
