Mailto: RiO RESEARCH: Profile >> GotoMenu The working group Computational Ecotoxicology at the Institute for Environmental Research focuses on complexity in structures and processes of hierarchical dynamical bio-systems. We develop statistical, machine learning and AI-based algorithms and methods for multivariate modeling, pattern recognition, causal analysis and prediction in life-science disciplines like ecology, ecotoxicology and biomedical research. To link available lines of evidence (i.e. theory, simulation and observation) techniques from statistical pattern recognition, machine learning, data mining and bioinformatics as well as approaches from complex systems theory and chaos theory are used in a wide field of applications. More detailed attention is paid to non-linear dynamics, self-organization processes, the role of information and entropy, the integration of expert knowledge into modelling processes as well as epistemological consequences. In our most recent research we apply the developed methods in questions about: Chemobehavioral profiling using Danio rerio video tracking data Expert-augmented statistics in ecotoxicological bio-testing Special long-term research questions we are interested in are: Non-linear dynamics: Bifurcation and chaotic dynamics and their implications for the stability and resilience of natural agent-based systems Entropy: Negentropic information flow and its relation to self-organization in dissipative living systems Networks: Integration of theory and observations to assess ecosystem integrity Complexity: Emerging phenomena and their relevance to ecological structures and dynamics Limitations: Gdels incompleteness theorems and their implications for modelling in the life sciences Understanding of patterns and processes in living systems requires a flexible range of data analysis techniques. Simulation using mathematical models, statistics and theoretical analysis of model equations are important generic tools to interpret and underpin results from lab and field observations. These in-silico-experiments are equally relevant to setting up and analysing laboratory experiments. They allow integration of empirical observations and theoretical models to generate and test multifactorial hypotheses. Such a system-oriented approach helps to elucidate structures, processes and dynamics in complexly interacting biological systems, e.g. ecological communities, gene expression networks and the immune system.

Mailto: RiO RESEARCH: Profile >> GotoMenu The working group Computational Ecotoxicology at the Institute for Environmental Research focuses on complexity in structures and processes of hierarchical dynamical bio-systems. We develop statistical, machine learning and AI-based algorithms and methods for multivariate modeling, pattern recognition, causal analysis and prediction in life-science disciplines like ecology, ecotoxicology and biomedical research. To link available lines of evidence (i.e. theory, simulation and observation) techniques from statistical pattern recognition, machine learning, data mining and bioinformatics as well as approaches from complex systems theory and chaos theory are used in a wide field of applications. More detailed attention is paid to non-linear dynamics, self-organization processes, the role of information and entropy, the integration of expert knowledge into modelling processes as well as epistemological consequences. In our most recent research we apply the developed methods in questions about: Chemobehavioral profiling using Danio rerio video tracking data Expert-augmented statistics in ecotoxicological bio-testing Special long-term research questions we are interested in are: Non-linear dynamics: Bifurcation and chaotic dynamics and their implications for the stability and resilience of natural agent-based systems Entropy: Negentropic information flow and its relation to self-organization in dissipative living systems Networks: Integration of theory and observations to assess ecosystem integrity Complexity: Emerging phenomena and their relevance to ecological structures and dynamics Limitations: Gdels incompleteness theorems and their implications for modelling in the life sciences Understanding of patterns and processes in living systems requires a flexible range of data analysis techniques. Simulation using mathematical models, statistics and theoretical analysis of model equations are important generic tools to interpret and underpin results from lab and field observations. These in-silico-experiments are equally relevant to setting up and analysing laboratory experiments. They allow integration of empirical observations and theoretical models to generate and test multifactorial hypotheses. Such a system-oriented approach helps to elucidate structures, processes and dynamics in complexly interacting biological systems, e.g. ecological communities, gene expression networks and the immune system.
