I am a computational social scientist working on modeling, analyzing, and designing socio-economic systems. As a basis for this, I often engage in social data science, doing unconventional data analysis for interesting phenomena.

From my background in mathematics, I consider myself still an applied mathematician but through extensive postgraduate study and research also a and social scientist.
Research Topics: social cohesion, processes of opinion formation, polarization, processes of segregation, processes of decision making, aggregation of the wisdom of crowds, rating systems, voting systems, consensus algorithms, cascades on networks, systemic risk
Tools: agent-based modeling and simulation, large-scale data analysis, experiments, mathematical and statistical analysis
Mathematical fields: nonnegative matrices, inhomogeneous Markov chains, repeated application of means, positive dynamical systems, multiplicative and additive stochastic processes
General scientific interests: game theory, mathematics and politics, social choice, socio- and econophysics, complex systems, networks
